Denudation processes affecting mountain slopes may vary according to different factors (e.g., lithology and structural setting of bedrock, climate, relief features), which may be very diverse at the local scale. Gully complex systems, characterised by morphological features similar to those developing in other climate contexts (i.e., pseudo-badlands) are also becoming common at higher altitudes and latitudes. The selected study cases of Gran Gorgia (Susa Valley) and Saint Nicolas (Aosta Valley), in theWestern Italian Alps, are sites of geomorphological interest as they are specifically relevant for their scientific features. The aims of this work are (i) reconstructing the morphometric evolution of gully systems and vegetation colonisation time by means of multitemporal spatial analysis on surface morphological changes under water erosion; (ii) reconstructing in detail, through dendrogeomorphological analysis, the progressive spatial surface denudation and changes in erosion rates, by analysing trees and exposed roots and using different indicators (i.e., compression wood, traumatic resin ducts); (iii) obtaining data on successive aggradation/degradation episodes along slopes surrounding such hotspots through geopedological investigations; and (iv) identifying which control factors exert a predominant role on denudation patterns in such contexts. Multidisciplinary analyses regarding the study sites allowed for detailing of erosional history of the studied slopes detecting the prevailing drivers of their evolution. According to the results and considering the common climate and bedrock conditions, the structural background seems to have more influence on slope evolution at the Saint Nicolas site, while superficial geomorphic processes seem to be more relevant at the Gran Gorgia site. Because the sites have already been recognised as part of geoheritage by local authorities, the data obtained in the present research on their genesis, evolution, and local drivers affecting the rates of denudation (i.e., scientific relevance of the site) suggests that description of the sites for dissemination purposes should include links to the entire slope history.

Torrent control works, such as grade control dams and sediment retention dams, are structural measures for controlling debris flows and debris floods. In spite of the widespread presence of such hydraulic structures in steep mountain streams worldwide, there are still few studies monitoring the effects of check dams on sediment dynamics. The use of repeated topographic surveys allows us to characterize debris-flow activity at multiple temporal and spatial scales and its interaction with torrent control works. Structure from Motion (SfM) technique paired with Multi-View Stereo (MVS) algorithms represents a low-cost opportunity to conduct such multi-temporal surveys. This enables us to better study the effects of individual debris flows, track geomorphic changes and evaluate the effectiveness of torrent control works (e.g. check dams). The effect of check dams on sediment dynamics is investigated by means of multi-temporal topographic surveys before and after debris-flow events in the Moscardo torrent (eastern Italian Alps) where two check dams have recently been built. Multi-temporal SfM based on images taken from the ground in combination with imagery taken by an Unmanned Aerial Vehicle (UAV) is used to obtain DEMs and to study topographic changes through the comparison of repeat DEMs (DEM of Difference, i.e. DoD). The results show that the new check dams considerably modified sediment dynamics in the studied channel but their performance cannot be considered satisfactory. The sediment flowed around the upstream check dam on the right wing, while deep erosion observed downstream of the check dam threatened to undermine the foundation's stability. Moreover, debris-flow lobes deposited upstream of the check dams could act as sources of sediment further increasing downstream debris-flow volume. The analysis proposed in this work could help improve design strategies and permitting the identification of a proper site for check dam building.

In the last decade, conservation agriculture (CA) has received particular attention from both governmental and non-governmental organizations. CA aims to achieve sustainable agricultural production. The principles of CA include minimal soil disturbance, permanent soil cover derived from crop residues or cover crops, and crop rotations that benefit soil and water conservation. Agricultural practices influence the micro-topography and modify the surface roughness, altering several important processes such as infiltration, water storage depression, and soil water erosion. In this work, we explore the effectiveness of high-resolution topography in characterizing no-tillage (NT) versus conventional tillage (T) surface morphology in order to better understand the hydro-geomorphic processes associated with these crop systems. High-resolution (2 cm) Digital Elevation Models (DEMs), derived using the Structure from Motion (SfM) photogrammetric technique, were processed for six plots (3 cultivated with NT, 3 with T) in a clay loam soil. The study area is located in northeast Italy. Several morphometric terrain parameters (e.g., connectivity, curvature and relative elevation attribute), were computed for each plot. The analysis provided challenging insights_ compared to T, surfaces in the NT plots were rougher, had more pronounced slopes and curvatures, sediments with a widespread connection to the plot boundaries, had more irregular flow paths, and had a higher water storage potential due to surface concavities. This can be translated into a surface morphology that can significantly affect surface runoff, sediment transport, and the off-site movement of agricultural chemicals. ? 2018 Elsevier B.V.

Landslide inventory maps are commonly prepared
through the visual interpretation of stereoscopic aerial photographs
and field checks. Stereoscopic satellite images can also be
interpreted visually to recognize and map landslides. When
interpreting stereoscopic imagery, shadows can conceal the photographic
elements typical of landslides, hampering the recognition
and mapping of the landslides. To mitigate the problem, we
propose a method that exploits normalized difference vegetation
index (NDVI) images and digital stereoscopy for the 3D visual
recognition and mapping of landslides in shadowed areas. We
tested the method in the 25 km2 Pogliaschina catchment, northern
Italy, where intense rainfall caused abundant landslides on 25
October 2011. Using a PLANAR® StereoMirror(TM) digital stereoscope,
we prepared an event landslide inventory map (E-LIM)
through the visual interpretation of a pair of NDVI images obtained
from a WorldView-2 stereoscopic multispectral bundle. We
compared the event inventory with two independent E-LIMs for
the same area and landslide event. The 3D vision of the NDVI
stereoscopic image pair maximized the use of the radiometric
(color and tone) and the terrain (elevation, slope, relief, and
convexity) information captured by the stereoscopic multispectral
images, allowing for the recognition of more landslides and more
landslide areas than the other E-LIMs in the shadowed areas. Our
results confirm that use of NDVI images facilitates the visual
recognition and mapping of landslides in terrain affected by
shadows. We expect that the proposed method can help trained
interpreters to map landslides more accurately in areas affected by
shadows.

The paper presents a multidisciplinary analysis carried out for the characterization and monitoring of a levee in Bozen Province, North Italy. The study treats a small section of the Adige river embankments, interested in the recent past by moderate piping phenomena and subjected to some subsequent interventions for the risk mitigation. The data acquired with an Electrical Resistivity Tomography (ERT) investigation and an optical fiber distributed temperature sensing (DTS) are compared to boreholes information, laboratory tests and piezometers measurements. They provided a multi-dimensional characterization of the levee and of the close subsoil water-meadows, possible piping preferential paths. Since the presence of more permeable lenses within the silty matrix characterizing the levee foundations, the subsequent 2D seepage analysis was carried out with the Boolean Stochastic Generation (BoSG) method, which randomly generates lenses with specific rheological properties within a matrix with another set of parameters. The soil configurations that are more congruent with the monitoring data were selected within a pool of 360 simulations, providing information about the probable seepage mechanism within the levee and the reliability of the interventions.

The use of Remotely Piloted Aircraft Systems (RPASs) in geosciences is often aimed at the acquisition of an image sequence to produce digital models and orthophotographs of the topographic surface. The technology can be applied for rockfall hazard and risk assessment. To study rockfalls, an approach consists in the application of numerical models for the computation of rockfall trajectories. Data required for such models include accurate digital terrain models, location of the instability source areas, and the mechanical properties of the terrain. In this article, we present an analysis of the earthquake-triggered rockfall that occurred along the SP18 in Villanova di Accumoli (Lazio, central Italy) during the 24 August 2016 seismic sequence. A survey with a multicopter was carried out to obtain an accurate surface model of the terrain, the identification and characterization of the source areas and of other instable blocks in areas not accessible in the field. The investigated area extends for 6,500m2 and was covered by 161 photographs that were used to obtain an orthophoto with a ground resolution of 2.5cm, and a digital surface model with a ground resolution of 20cm×20cm, which was processed and fused with GNSS RTK data. We run the numerical model STONE, using the source areas mapped in the field and adopting a slope threshold to get a map showing the rockfall potential trajectories. Results showed that only the part of the road SP18 hit by the rockfall was exposed to further rockfall impacts. In particular, it was observed that 16% (i.e. 5,108) of the 31,800 simulated trajectories reached or crossed this tract of the road. Based on these data, limited protection measures were suggested. The combined use of RPAS data, fused with ground GPS points, an accurate geomorphological survey, and terrain static and dynamic parameters from the literature, allows fast, low-cost and replicable numerical modelling for emergency response and adoption of proper protection measures.

The Mediterranean region is an area potentially vulnerable to climatic changes. In fact, it is characterized by a significant precipitation variability resulting from synoptic dynamics of hazardous events moving and evolving along the Mediterranean basin. In this paper, the results of an investigation on rainfall trend in the Sardinia region are presented. The trend analysis has been performed by means of the Mann-Kendall test and of the Theil-Sen estimator applied on annual, seasonal, and monthly scales. To this aim, a monthly database of precipitation registered at 158 rain gauges, with an average observation of 84 years, was used for the analyses. The results mainly evidenced a rainfall amount reduction in the winter months and an increase during the summer months. The monthly rainfall distribution throughout the year was also investigated by means of the precipitation concentration index (PCI). A negative trend emerged and, more specifically, a tendency towards a more uniform rainfall distribution on the Sardinia region throughout the year.

Abstract
Background_ in the Mediterranean environment, floods pose a significant threat to people, in spite
of the noteworthy improvements in forecasting, emergency management and defensive works.
Methodology_ this paper examines flood mortality in the Mediterranean environment based on a
36-year long database (1980-2015) that was built in five study areas using documentary sources.
Information on fatal accidents was disaggregated in database fields describing victim's profile and
the circumstances of the accidents.
Results_ data show an increasing trend of flood fatalities during the study period. Accidents mainly
occurred outdoor_ the majority of the 458 fatalities were males, mainly aged between 30 and 49
years, and residents in the area of the accident. In the majority of cases, people were dragged by
water/mud when travelling by car. Some cases of hazardous behaviours, such as fording rivers or
trying to save belongings, were also detected. The cause of death was drowning in the majority of
cases, and heart attack in a few cases it was.
Significance_ the results of the research can be proficiently used in information campaigns aiming
to increase people safety during future floods.

In this paper, a stochastic model, previously proposed for the maximum daily temperature, has been improved for the combined analysis of mean daily temperature and diurnal temperature range. In particular, the procedure applied to each variable sequentially performs the deseasonalization, by means of truncated Fourier series expansions, and the normalization of the temperature data, with the use of proper transformation functions. Then, a joint stochastic analysis of both the climatic variables has been performed by means of a FARIMA model, taking into account the stochastic dependency between the variables, namely introducing a cross-correlation between the standardized noises. The model has been applied to five daily temperature series of southern Italy. After the application of a Monte Carlo simulation procedure, the return periods of the joint behavior of the mean daily temperature and the diurnal temperature range have been evaluated. Moreover, the annual maxima of the temperature excursions in consecutive days have been analyzed for the synthetic series. The results obtained showed different behaviors probably linked to the distance from the sea and to the latitude of the station.

Soil moisture is a key environmental variable, important to, e.g., farmers, meteorologists, and disaster management units. Here, we present a method to retrieve surface soil moisture (SSM) from the Sentinel-1 (S-1) satellites, which carry C-band Synthetic Aperture Radar (CSAR) sensors that provide the richest freely available SAR data source so far, unprecedented in accuracy and coverage. Our SSM retrieval method, adapting well-established change detection algorithms, builds the first globally deployable soil moisture observation data set with 1-km resolution. This paper provides an algorithm formulation to be operated in data cube architectures and high-performance computing environments. It includes the novel dynamic Gaussian upscaling method for spatial upscaling of SAR imagery, harnessing its field-scale information and successfully mitigating effects from the SAR's high signal complexity. Also, a new regression-based approach for estimating the radar slope is defined, coping with Sentinel-1's inhomogeneity in spatial coverage. We employ the S-1 SSM algorithm on a 3-year S-1 data cube over Italy, obtaining a consistent set of model parameters and product masks, unperturbed by coverage discontinuities. An evaluation of therefrom generated S-1 SSM data, involving a 1-km soil water balance model over Umbria, yields high agreement over plains and agricultural areas, with low agreement over forests and strong topography. While positive biases during the growing season are detected, the excellent capability to capture small-scale soil moisture changes as from rainfall or irrigation is evident. The S-1 SSM is currently in preparation toward operational product dissemination in the Copernicus Global Land Service.

Thanks to the large number of satellites, the multimission approach is becoming a viable method to integrate measurements and intensify the number of samples in space and time for monitoring the earth system. In this paper, we merged data from different satellite missions, optical sensors, and altimetry, for estimating daily river discharge through the application of the artificial neural network (ANN) technique. ANN was selected among other retrieval techniques because it offers an easy but effective way of combining input data from different sources into the same retrieval algorithm. The network is trained in a calibration period and validated in an independent period against in situ observations of river discharge for two gauging sites_ Lokoja along the Niger River and Pontelagoscuro along the Po River. For optical sensors, we found that the temporal resolution is more important than the spatial resolution for obtaining accurate discharge estimates. Our results show that Landsat fails in the estimation of extreme events by missing most of the peak values due to its long revisit time (14-16 days). Better performances are obtained from Moderate Resolution Imaging Spectroradiometer (MODIS) and Medium Resolution Imaging Spectrometer. Radar altimetry provides results in between MODIS-TERRA and MODIS-AQUA at Lokoja, whereas it outperforms all single optical sensors at Pontelagoscuro. The multimission approach, involving optical sensors and altimetry, is found the most reliable tool to estimate river discharge with a relative root-mean-square error of 0.12% and 0.27% and Nash-Sutcliffe coefficient of 0.98 and 0.83 for the Niger and Po rivers, respectively.

Droughts often evolve gradually and cover large areas, and therefore, affect many people and activities. This motivates developing techniques to integrate different satellite observations, to cover large areas, and understand spatial and temporal variability of droughts. In this study, we apply probabilistic techniques to generate satellite derived meteorological, hydrological, and hydro-meteorological drought indices for the world's 156 major river basins covering 2003-2016. The data includes Terrestrial Water Storage (TWS) estimates from the Gravity Recovery And Climate Experiment (GRACE) mission, along with soil moisture, precipitation, and evapotranspiration reanalysis. Different drought characteristics of trends, occurrences, areal-extent, and frequencies corresponding to 3-, 6-, 12-, and 24-month timescales are extracted from these indices. Drought evolution within selected basins of Africa, America, and Asia is interpreted. Canonical Correlation Analysis (CCA) is then applied to find the relationship between global hydro-meteorological droughts and satellite derived Sea Surface Temperature (SST) changes. This relationship is then used to extract regions, where droughts and teleconnections are strongly interrelated. Our numerical results indicate that the 3- to 6-month hydrological droughts occur more frequently than the other timescales. Longer memory of water storage changes (than water fluxes) has found to be the reason of detecting extended hydrological droughts in regions such as the Middle East and Northern Africa. Through CCA, we show that the El Niño Southern Oscillation (ENSO) has major impact on the magnitude and evolution of hydrological droughts in regions such as the northern parts of Asia and most parts of the Australian continent between 2006 and 2011, as well as droughts in the Amazon basin, South Asia, and North Africa between 2010 and 2012. The Indian ocean Dipole (IOD) and North Atlantic Oscillation (NAO) are found to have regional influence on the evolution of hydrological droughts.

To solve conservation and planning challenges in the marine environment, researchers are increasingly developing geospatial tools to address impacts of anthropogenic activities on marine biodiversity. The paper presents a comprehensive set of built-in geospatial webtools to support Maritime Spatial Planning (MSP) and environmental management objectives implemented into the Tools4MSP interoperable GeoPlatform. The webtools include cumulative effects assessment (CEA), maritime use conflict (MUC) analysis, MSFD pressure-driven CEA and a CEA-based marine ecosystem service threat analysis (MES-Threat). The tools are tested for the Northern Adriatic (NA) Sea, one of the most industrialized sea areas of Europe using a case study driven modelling strategy. Overall results show that coastal areas within 0-9 nm in the Gulf of Trieste, Grado-Marano and Venice lagoon and Po Delta outlet are subjected to intense cumulative effects and high sea use conflicts mainly from port activities, fishery, coastal and maritime tourism and maritime shipping. Linking MES into CEA provided novel information on locally threatened high MES supporting and provisioning habitats such Cymodocea beds and infralittoral fine sands, threats to cultural MES are most pronounced in coastal areas. Results are discussed for their geospatial relevance for regional planning, resource management and their applicability within MSP and environmental assessment.

On June 24, 2017 (21:39 UTC, June 23rd), a catastrophic landslide occurred at Xinmo village of Mao County, Sichuan Province, China. Soon after the event, some research teams carried out field investigations in order to both support the emergency operations and to understand the failure mechanism and possible evolutionary scenarios. Based on further in-depth interpretation of high-resolution remote-sensing images and detailed field surveys, it is newly found that there are at least six old rockfall deposits in the source area that prove the historic activity of the landslide scarp. Seismic data of the event and morphological evidences along the slope indicate that the landslide was preceded by a significant rockfall. Mechanical calculations show that the surface force due to pore water was far less than the impact force due to the rockfall. It means that the subsequent major rock avalanche was more likely due to the impact of the rockfall on the rock slope below, which broke the rock bridges and caused drop of shear resistance along the fractures. According to these new understandings, a different triggering mechanism for the landslide is proposed.

The Open Science approach delineates high and inspiring principles. In order to really root
them into the scientific community, a cultural shift must occur that can be fostered and
achieved mainly through the development of practical case studies. This is particularly
relevant in the field of ecology, a highly multidisciplinary science, where the Open Science
issue has become a matter of discussion only in very recent years. In particular, in the
context of long-term ecological research, enabling open sharing of in-situ and derived longterm
ecological data is required to advance research and education in the European and
global networks.

A seguito degli eventi sismici verificatisi a partire dal 24 agosto 2016 in Italia centrale, ...
A seguito degli eventi sismici verificatisi a partire dal 24 agosto 2016 in Italia centrale, il Commissario Straordinario di Governo per la Ricostruzione (CSGR), della Presidenza del Consiglio dei Ministri, ha espresso la necessità di pervenire alla definizione di un Piano dei Dissesti Idrogeologici (PDI), così come previsto dal DL 189/2016, art.14, finalizzato a valutare le condizioni di pericolosità da frana e da inondazione nelle aree interessate dalle Perimetrazioni (ai sensi dell'Ordinanza n.25 del 2017), necessarie per avviare una corretta programmazione degli interventi di ricostruzione dei centri abitati maggiormente colpiti dal sisma.
Visto le specifiche competenze che l'Istituto di Ricerca per la Protezione Idrogeologica (IRPI) del Consiglio Nazionale delle Ricerche (CNR) ha acquisito sulla valutazione delle condizioni di pericolosità e di rischio geo-idrologico (geomorfologico ed idraulico), anche maturate in qualità di Centro di Competenza CNR del Dipartimento della Protezione Civile (DPC), il CNR IRPI si è reso disponibile a fornire al CSGR un supporto tecnico-scientifico per la valutazione delle condizioni di pericolosità e di rischio geo-idrologico nei territori dei Comuni delle Regioni Abruzzo, Lazio, Marche e Umbria, interessati dagli eventi sismici verificatisi a partire dal 24 agosto 2016.
Le attività che il CNR IRPI ha svolto su richiesta del CSGR sono le seguenti_
o partecipazione ad incontri (tavoli tecnici) con il Distretto dell'Appennino centrale per la definizione di un "piano conoscitivo di riferimento dei fenomeni di dissesto geo-idrologico";
analisi degli studi esistenti relativi ai pericoli e ai rischi geo-idrologici per i territori dei Comuni di Visso, Ussita e Castelsantangelo sul Nera;
o predisposizione di una scheda tecnica, funzionale alla costruzione del Piano dei Dissesti, per la raccolta di informazioni sul rischio geo-idrologico;
definizione dei criteri per la gerarchizzazione delle richieste degli interventi necessari alla mitigazione del rischio geo-idrologico;
o confronto tra le richieste degli interventi di mitigazione del rischio geo-idrologico con le informazioni dei progetti già finanziati attraverso il Repertorio Nazionale degli interventi per la Difesa del Suolo (ReNDiS).
Le attività sono state svolte dal CNR IRPI nel periodo compreso fra il novembre 2017 e il marzo 2018. Le attività sono state condotte da_ (i) due Ingegneri Idraulici e da due Geologi, per la partecipazione agli incontri con il Distretto dell'Appennino centrale e per l'analisi degli studi esistenti relativi ai pericoli e ai rischi geo-idrologici per i territori dei Comuni di Visso, Ussita e Castelsantangelo sul Nera; e da (ii) quattro Geologi e due Ingegneri Idraulici per la predisposizione di una scheda tecnica, funzionale alla costruzione del Piano dei Dissesti, e per l'analisi e il confronto delle informazioni sul rischio geo-idrologico.

Descrizione: tool sviluppato mediante un codice di calcolo scritto in R open-source software (release 3.3.3 (http://www.r-project.org). Il tool permette, a partire da dati di pioggia e frana, di ricostruire automaticamente gli eventi di pioggia, le condizioni di innesco per frane pluvio-indotte e di calcolare le soglie pluviometriche e le incertezze associate ad esse per diverse percentuali di non superamento. Il tool è strutturato secondo tre distinti blocchi. Nel primo blocco CTRL-T fornisce informazioni (data di inizio e fine evento, durata, cumulata, pioggia massima in 1he 24 h, classificazione evento, etc) relative alla ricostruzione degli eventi di pioggia eseguita analizzando ciascun pluviometro disponibile come dato in Input. Nel blocco successivo CTRL-T, utilizzando le informazioni spazio-temporali di tutte le frane disponibili, calcola le condizioni di innesco per i pluviometri contenuti all'interno di un buffer circolare di raggio scelto, associando ad esse un peso variabile in base alla distanza del pluviometro dalla frana, alla durata e alla cumulata dell'evento di pioggia associato alla frana contenente la frana. Utilizzando queste informazioni il tool è in grado di discriminare il pluviometro rappresentativo tra quelli analizzati e di selezionare per quest'ultimo le condizioni di innesco utilizzate successivamente per definire le soglie. Nell'ultimo blocco (blocco 3) il tool, utilizza le condizioni di innesco definite per ciascuna frana e calcola le soglie pluviometriche (a diversi percentili di non superamento) mediante il metodo frequentista. Per ciascuna soglia, infine, il tool associa un'incertezza derivante da procedure di bootstrap integrate al calcolo della soglia stessa. In Output CTRL-T fornisce (per ciascuno dei tre blocchi) file di testo e file pdf contenenti i risultati ottenuti sottoforma di grafici e tabelle (data frame).

Soil moisture plays a key role in many fields, such as drought management, weather forecasting, agriculture and natural hazards assessment. For the latter, soil moisture is used beneficially in hydrological modeling for flood hazard mitigation while for landslides assessment its use is very rare. Satellite-based products are available at high temporal and spatial resolution, providing accurate estimates of soil moisture over large areas. In this study, soil moisture data obtained through the Advanced SCATterometer (ASCAT) are used to investigate the role of satellitederived soil moisture observations on the possible occurrence of landslides in Italy. To this end, a catalogue of more than 1000 shallow landslides occurred in Italy during the period 2007-2015 and the rainfall ground observations from 600 rain gauges are used. The rainfall events that likely triggered every landslide have been identified by manual inspection of the pluviographs, considering standardized criteria. The soil moisture conditions prior the precipitation event and the total rainfall amount are used to identify the triggering conditions for the Italian territory. The analysis provided promising results, although the coarse spatial resolution (12.5 km) could limit the capabilities of the remotely sensed information of defining the correct coil saturation conditions. The use of higher soil moisture products, e.g. Sentinel-1 derived data, could improve the performance of such approach, and will be presented at the conference.

In Italy, heavy rainfall events often have significant consequences. Such events may trigger landslides, which frequently cause severe socio-economic damage.
Here, we analyze satellite-based rainfall products to evaluate their capability in forecasting the spatio-temporal occurrence of landslides induced by heavy rainfall. Three different satellite rainfall estimates are used_ 1) the Tropical Rainfall Measurement Mission Multi-satellite Precipitation Analysis, TMPA, real time product (3B42-RT), 2) the SM2RASC product obtained from the application of SM2RAIN algorithm to the Advanced SCATterometer (ASCAT) derived satellite soil moisture data, and 3) the Climate Prediction Center (CPC) Morphing Technique (CMORPH). An automatic tool is used to reconstruct distinct rainfall events from satellite-based data. Three classes of events, "Heavy", "Heavy/Torrential", and "Torrential", are identified and selected, based on the maximum cumulated rainfall in 24 h. Then, exploiting a historic catalogue of failures occurred in Italy from 2008 to 2017 rainfall events responsible for the observed landslides are extracted in the three classes. Most (85%) of the selected events related to landslides are used to define rainfall thresholds. The remaining (15%) events with landslides and all the events not related to landslide occurrences are used to assess the threshold performance through skill scores and receiver operating characteristic (ROC) analysis.

Information on historical landslides and floods collectively called "geo-hydrological hazards - is key to understand the complex dynamics of the events, to estimate the temporal and spatial frequency of damaging events, and to quantify their impact. A number of databases on geo-hydrological hazards and their consequences have been developed worldwide at different geographical and temporal scales. Of the few available database structures that can handle information on both landslides and floods some are outdated and others were not designed to store, organize, and manage information on single phenomena or on the type and monetary value of the damages and the remediation actions. Here, we present the LANDslides and Floods National Database (LAND-deFeND), a new database structure able to store, organize, and manage in a single digital structure spatial information collected from various sources with different accuracy. In designing LAND-deFeND, we defined four groups of entities, namely_ nature related, human-related, geospatial-related, and information-source-related entities that collectively can describe fully the geo-hydrological hazards and their consequences. In LAND-deFeND, the main entities are the nature-related entities, encompassing_ (i) the "phenomenon", a single landslide or local inundation, (ii) the "event", which represent the ensemble of the inundations and/or landslides occurred in a conventional geographical area in a limited period, and (iii) the "trigger", which is the meteo-climatic or seismic cause (trigger) of the geo-hydrological hazards. LAND-deFeND maintains the relations between the nature-related entities and the human-related entities even where the information is missing partially. The physical model of the LAND-deFeND contains 32 tables, including nine input tables, 21 dictionary tables, and two association tables, and ten views, including specific views that make the database structure compliant with the EC INSPIRE and the Floods Directives. The LAND-deFeND database structure is open, and freely available from http_//geomorphology.irpi.cnr.it/tools. (C) 2017 The Authors. Published by Elsevier Ltd.

Abstract

Floods are frequent and widespread in Italy and pose a severe risk for the population. Local administrations commonly
use flow propagation models to delineate the flood prone areas. These modeling approaches require a detail geoenvironmental data knowledge, intensive calculation and long computational times. Conversely, statistical methods can
be used to asses flood hazard over large areas, or to extend the flood hazard zonation to the portion of the river networks
where hydraulic models have still not been applied or can be applied with difficulties. In this paper, we describe a
statistical approach to prepare flood hazard maps for the whole of Italy. The proposed method is based on a multivariate
machine learning algorithm calibrated using in input flood hazard maps delineated by the local authorities and terrain
elevation data. The preliminary results obtained in several major Italian catchments indicate good performances of
the statistical algorithm in matching the training data. Results are promising giving the possibility to obtain reliable
delineations of flood prone areas obtained in the rest of the Italian territory.

Abstract
The 4th Open Source Geospatial Research and Education Symposium (OGRS 2016) was organized by the ...
The 4th Open Source Geospatial Research and Education Symposium (OGRS 2016) was organized by the Research Institute for Geo-hydrological Protection (IRPI) of the Italian National Research Council (CNR), in Perugia (Central Italy) in the period 12-14 October 2016. During those days a seismic sequence hit this part of the country with two major earthquakes (August 24 and October 30) and the IRPI institute intensively engaged in field survey activities. Therefore we are even more grateful to the people who decided to attend the symposium in Perugia under these conditions.
OGRS is an interdisciplinary conference dedicated to sharing knowledge, new solutions, methods, practices, ideas and trends in the field of geospatial information through the development and the use of free and open source software in both research and education.
The conference is built around the spirit of open science and promotes all the processes based on cooperative work and new ways to diffuse scientific knowledge by using open data, open standards, open source and open publications. OGRS is not only a vision of the future but also an opportunity for geoscientists and geoteachers to build together new methods and tools to meet the new challenges of humanity that require a systemic and collaborative response.
The OGRS2016 conference offered two days of scientific presentations and one day of Workshops. Grouped by thematic sessions, presentations (including posters as well) described original and recent research results, educational practices and innovation experiences. Workshop sessions on specific topics and software have reinforced the educational dimension of the Symposium.
Fifty-five contributions (short papers) were submitted to the symposium. The short papers were rapidly made available online in an "OGRS2016 Collection", using the PeerJ PrePrint publication system and were independently reviewed by at least two referees chosen among the eminent colleagues who accepted to be part of the Scientific Committee. The review process was carried out through an open procedure consisting of referees comments and authors replies which are still accessible online at the following link_ https_//peerj.com/collections/35-open-source-geospatial-research-and-education-symposium-2016/ (short version_ https_//goo.gl/5RBC27).
Fifty one of the originally submitted manuscripts were included in the OGRS2016 program and are included in the present book of the symposium proceedings.
The symposium was enriched by 3 keynote talks_ Maurizio Napolitano (Fondazione Bruno Kessler, Italy), Riccardo Rigon (University of Trento, Italy), Maria Brovelli (Politecnico di Milano, Italy).
As mentioned before, OGRS2016 also included workshops. They focused on specific topics and software and have reinforced the education side of the Symposium. We want to sincerely thank all the colleagues and friends who organized the workshops, shared and disseminated their knowledge among the participants.
The event could not have been organized without the support of the Research Institute for Geo-Hydrological Protection of the National Research Council of Italy, through its Director Fausto Guzzetti and of all the other friends and colleagues who are working for this institution.
The symposium was also supported by other institutions and persons in particular by Pierluigi de Rosa, from the Department of Physics & Geology of the University of Perugia, who has provided a substantial and fundamental aid in the organization of the event.
We also thank the members of the OGRS steering Board, and in particular Olivier Ertz from the University of Applied Sciences and Arts of Western Switzerland (HEIG-VD), Stéphane Joost from the École Polytechnique Fédérale de Lausanne (EPFL), Erwan Bocher and Gwendal Petit from the CNRS LAB-STICC laboratory (Laboratoire des Sciences et Techniques de l'Information, de la Communication et de la Connaissance) in France. They supported the scientific organization of the event.
We want to stress also the important patronages of the main administrative authorities of Perugia_ the Legislative Assembly of the Umbria Region, the Province of Perugia and the Municipality of Perugia.
Finally we also want to mention the support provided to the symposium by the Italian Geological Society, the Hazard and Risk Commission of the International Geographical Union, the Italian OSGeo Local Chapter and the Society of Professional Engineers of the province of Perugia.

Structured documentation on natural hazards is a key for (i) planning mitigation strategies and understanding their
effectiveness, (ii) developing vulnerability curves for the quantitative estimation of the risk, (iii) analyzing the
threat posed by the climate induce disasters to the built environment and the individuals.
Among the other natural hazards, landslides and floods, hereinafter referred to as "geo-hydrological hazards", are
frequently triggered by intense and prolonged rainfall event, causing impacts and damage on the same area in a
short time.
The spatial and temporal frequency of geo-hydrological events and their impacts can be studied through the analysis of dedicated catalogues compiled at national or regional scales, where the medium/long-term actions for risk
mitigation strategies and land management are planned at administrative levels.
A number of databases and digital catalogues on natural hazards exist and were used for different scopes, including
research, insurance and economic purposes. The analysis of the existing databases dealing with geo-hydrological
hazards, at national scale, reveals some limitations_ (i) missed separation between the geographical location of
events and the location of their consequences or of the mitigation measures, (ii) non-compliance with the recent
European Commission EC directives on digital archives of natural hazards, (iii) inadequacy of the database structure for the compilation at different scale, (iv) partial focus on a single type of phenomenon (landslide or flood),
(v) restrictions on the type of geometry (point, line, polygon) to be used for the geospatial representation (e.g.
landslide shape, road, inundated area, house).
Here we present LAND-deFeND, an acronym for LANDslides and Floods National Database, a database structure
designed for overcome these limitations and capable of recording non-homogeneous historical and recent informations on landslides and floods, their consequences, mitigations and related costs.
The conceptual design of LAND-deFeND is aimed at concentrate and manage in a single database structure all
the relevant information on historical and recent geo-hydrological hazard, even if derived from different sources,
dating back to different periods and provided with different levels of accuracies.
The main innovation of the LAND-deFeND database structure is in its conceptual model, and regards the identification of four groups of entities used to describe the geo-hydrological events and their socio-economic and
environmental impacts. The core of the database structure is represented by the three Nature-related entities that
we differentiated in hierarchical levels_ "phenomenon", "event" and "trigger". Common denominator of this distinction is an increasing level of complexity_ from the single localized phenomenon, to the more extended event,
to the widest meteo-climatic or seismic trigger. Each entity is freestanding from the others, but inherently connected by an association table. The structure allows storing the physical, geographical and socio-economic data at
different degrees of detail, and makes it possible to store at the same time extremely detailed data or aggregated
information.
To test LAND-deFeND more than one thousand records of events occurred in Italy in the period between 2000-
2015 were added. The database structure is released under the "Open Database License" (ODbL) and a simple
QGIS interface was used for data entry.

The inhabited zone of the Ugandan Rwenzori Mountains is affected by landslides, frequently causing loss of life, damage to infrastructure and loss of livelihood. This area of ca. 1230 km(2) is characterized by contrasting geomorphologic, climatic and lithological patterns, resulting in different landslide types. In this study, the spatial pattern of landslide susceptibility is investigated based on an extensive field inventory constructed for five representative areas within the region (153 km(2)) and containing over 450 landslides. To achieve a reliable susceptibility assessment, the effects of (1) using different topographic data sources and spatial resolutions and (2) changing the scale of assessment by comparing local and regional susceptibility models on the susceptibility model performances are investigated using a pixel-based logistic regression approach. Topographic data are extracted from different digital elevation models (DEMs) based on radar interferometry (SRTM and TanDEM-X) and optical stereophotogrammetry (ASTER DEM). Susceptibility models using the radar-based DEMs tend to outperform the ones using the ASTER DEM. The model spatial resolution is varied between 10, 20, 30 and 90 m. The optimal resolution depends on the location of the investigated area within the region but the lowest model resolution (90 m) rarely yields the best model performances while the highest model resolution (10 m) never results in significant increases in performance compared to the 20 m resolution. Models built for the local case studies generally have similar or better performances than the regional model and better reflect site-specific controlling factors. At the regional level the effect of distinguishing landslide types between shallow and deep-seated landslides is investigated. The separation of landslide types allows us to improve model performances for the prediction of deep-seated landslides and to better understand factors influencing the occurrence of shallow landslides such as tangent curvature and total rainfall. Finally, the landslide susceptibility assessment is overlaid with a population density map in order to identify potential landslide risk hotspots, which could direct research and policy action towards reduced landslide risk in this under-researched, landslide-prone region.
