Environmental planning is essential for the development of a region. For this purpose, one of the most commonly used tools in Italy is the municipal development plan (Piano Regolatore Generale, PRG). At strategic level one of the goals of the PRG is to establish a framework of knowledge and legal aspects on the geo-hydrological risk. Concerning landslide risk, PRG provides restrictions and regulations for new buildings and new forecasts of urban expansion in areas affected by landslides. Commonly, the PRG does not give any restriction based on landslide susceptibility. In this paper, we present an example of how a statistical landslide susceptibility model was implemented in the Perugia Municipality PRG. The PRG provides technical regulations to set the conditions for new forecasts of urban expansion and building, based on landslide susceptibility.

In Italy, rainfall-induced landslides are recurrent phenomena that cause societal and economic damage. Thus, assessing the rainfall conditions responsible for landslides is important and may contribute to reducing risk. The prediction of rainfall-induced landslides relies primarily on empirical rainfall thresholds. However, the thresholds are affected by uncertainties that limit their use in operational warning systems. A source of uncertainty lies in the characterization of the rainfall events responsible for landslides. Objective criteria for the definition of rainfall events are lacking. To overcome the problem, we propose an algorithm that reconstructs the rainfall events, identifies the rainfall conditions that have resulted in landslides, and measures the duration and the cumulated rainfall for the events. The algorithm is independent from the local settings and uses a reduced set of parameters to account for different physical settings and operational conditions. We tested the algorithm in Sicily, Italy, with rainfall and landslide information between January 2002 and December 2012. The rainfall conditions responsible for landslides identified by the algorithm were compared against results obtained manually. The algorithm was proven capable of accurately reconstructing most (87.7 %) of the rainfall events. For each landslide, the algorithm identified a variable number of rainfall conditions responsible for the failures, which are equally likely triggers of the landslide. This opens the possibility of evaluating the uncertainty introduced by different criteria to determine the rainfall events responsible for landslides. Use of the algorithm shall contribute to reducing the uncertainty in the definition of landslide-triggering rainfall events, to compiling large catalogues of rainfall events with landslides and to determining reliable rainfall thresholds for possible landslide occurrence.

Throughout the World, men have built terraced landscapes to gain ground suitable for cultivation in steep terrain.
Beyond the historical and cultural importance of terraced slopes, terraces have played an important role for soil
conservation and water management. In many areas, their abandonment has led to more frequent and/or abundant
geo-hydrological hazards. We analyse two terraced areas in northern Italy, including (i) the Valstagna prealpine
terraces (Veneto) where the Republic of Venice initiated the cultivation of tobacco in 1600, and (ii) the coastal
terraces of Santa Giulia di Centaura (Liguria) where terraces host vineyards and olive groves since 2000 years.
Using a combination of direct and indirect mapping methods and tools, including LiDAR topographic surveys, the
visual interpretation of aerial photographs and the analysis of historical maps, we performed a systematic mapping
of the terraces. Using the available maps, we determined statistics for the width, height and extent of stonewalls
and we evaluated the historical evolution of the terraces for the past 50 years, considering changes in land use,
the expansion of forest, and the changes in the precipitation regime. Finally, through a preliminary cost-benefit
analysis, we propose good practices to help the recovery of the terraces in the two study areas.

The Mont de La Saxe rockslide (Courmayeur, Aosta Valley, Italy) is presently one of the most hazardous landslides in Northern Italy. Due to increasing activity in the last 5 years, the rockslide has been extensively investigated and monitored. We present topographic
monitoring through ALS-LiDAR and TLS (Terrestrial Laser Scanning) surveys. This analysis is performed by visual comparison of LiDAR DEMs (1) in map and (2) profile format, and by the (3) elevation difference between successive DEMs. The efficacy of these three strategies depends on the rockslide kinematic, and the prevalence of either horizontal or vertical movements. In the first case, the visual comparison in map can be effective, while elevation difference is optimal to recognize prevalently vertical movements and areal extent of more active areas as well for a global zonation of the instability.

We present a procedure to use micro-UAV (Unmanned Aerial Vehicles) to perform photogrammetry survey and monitoring analysis in landslide scenarios. The employed methodology is mainly composed of two phases_ the first one is the UAV mission planning and execution, while the latter is the picture elaboration and alignment. The UAV used during all tests here described has been developed for photographic applications. Thanks to its "V" shape, propellers do not fall within camera field during normal flight operation and the eight motors configuration ensures more reliability in urban areas uses than a classical quadcopter configuration. The processing of the acquired photos relies on both standard photogrammetry procedure as well as innovative methods for photo alignment derived from computer vision algorithms. Examples of application are also provided to show the results and the potential of this methodology in real landslide scenarios.

The rock-cut city of Vardzia is a cave monastery site in south-western Georgia, excavated from the slopes of the Erusheti mountain on the left bank of the Mtkvari River. The main period of construction was the second half of the twelfth century. The caves stretch along the cliff for some eight hundred meters and up to fifty meters within the rocky wall. The monastery consists of more than six hundred hidden rooms spread over thirteen floors, which made possible to protect the monastery from the Mongol domination. The site was largely abandoned after the Ottoman takeover in the sixteenth century. The site is by the time affected by frequent slope instability processes along the entire volcanic tuff façade of the slope. Due to this phenomena the National Agency for Cultural Heritage Preservation of Georgia (NACHPG) has promoted, with the support of ISPRA, a landslide hazard assessment for the entire area through rock mechanics characterization, geotechnical engineering survey, geostructural and kinematic analysis, slope stability model, 3D laser scanner acquisitions and elaborations, and a real time monitoring system (GB_Radar interferometry) for the
identification of deformation path of the most hazardous areas. A field analysis was conducted to reconstruct geometry of the rocky cliff, characteristics of discontinuities, main failure modes and volume of potential unstable blocks and geomechanical parameters.

In this paper we describe a procedure for the study and management of rockfall affected areas. During the MASSA project, we defined a procedure for the management of the first emergency phase after the gravitational phenomenon, describing what it could be done for a first analysis and monitoring of the instable areas. In particular, the developed methodology considered three important aspects that should begin during the first 48-72 h_ (i) preliminary morphological/structural analysis; (ii) detection and monitoring of instable areas during the emergency phase; (iii) communication strategies for the event management and divulgation to the population. Starting from the defined methodology, we also describe the first results of the application of this method to the Quincinetto rockfall test site, Piedmont, Italy.

Il documento illustra le attività realizzate nel corso del 2014 nell'ambito dell'Accordo di
Collaborazione (AC) tra il Dipartimento della Protezione Civile (DPC) e il Centro di
Competenza (CC) dell'Istituto di Ricerca per la Protezione Idrogeologica (IRPI), del
Consiglio Nazionale delle Ricerche (CNR) [DA-007]. Le attività previste dal presente AC si
inquadrano nell'ambito dell'Accordo di Programma Quadro firmato dal Capo del
Dipartimento della Protezione Civile della Presidenza del Consiglio dei Ministri, e dal
Presidente del Consiglio Nazionale delle Ricerche [DA-002].
Le attività oggetto del presente AC sono aggiuntive e proseguono quelle previste dalle
precedenti intese operative [DA-005] e [DA-004] e dal precedente Accordo di
Collaborazione [DA-006]. Le attività descritte nel presente rapporto riguardano la
manutenzione e lo sviluppo del Sistema di Allertamento Nazionale per la previsione del
possibile innesco di fenomeni Franosi indotti da piogge (SANF). In particolare le attività
previste hanno riguardato l'aggiornamento dell'interfaccia attuale di SANF con l'aggiunta di
tool utili alla (i) consultazione dei dati di previsione interpolata, (ii) alla simulazione dei livelli
di criticità corrispondenti a scenari di pioggia misurata e prevista definiti dall'utente
permettendo anche l'utilizzo di differenti soglie di pioggia. Parallelamente a tali attività è
stato iniziato lo sviluppo di una nuova versione di SANF e in particolare si è proceduto (A)
a ridefinire la struttura dei database interni di SANF per consentire una maggiore efficienza
del sistema in sede di elaborazione e consultazione dei dati, (B) ad implementare un nuova
procedura di importazione dei dati di pioggia utilizzando il nuovo tool per l'interrogazione del
database del sistema EXPERIENCE, (C) ad implementare una procedura per il controllo
automatico dell'anagrafica dei sensori disponibili nel database del sistema EXPERIENCE;
(D) a ricodificare le procedure di calcolo del sistema SANF, ed infine (E) ad implementare
nuove strategie per l'importazione dei dati di pioggia prevista. Le modifiche effettuate
integrate nella nuova versione del sistema hanno anche avuto l'obiettivo di semplificare
l'esportabilità del sistema in diversi ambiti geografici, come quelli regionali, e di consentire
l'utilizzo congiunto di più soglie per il calcolo dei livelli di criticità da frana.

Abstract

There is evidence that the precipitation pattern in Europe is trending towards more humid conditions in the northernregion and drier conditions in the southern and central-eastern regions. However, a great deal of uncertainty concerns how the changes in precipitations will have an impact on water resources, particularly on groundwater, and this uncertainty should be evaluated on the basis of that coming from 1) future climate scenarios of Global Circulation Models (GCMs) and 2) modeling chains including the downscaling technique, the infiltration model and the calibration/validation procedure used to develop the groundwater flow model. With the aim of quantifying the uncertainty of these components, the Valle Umbra porous aquifer (Central Italy) has been considered as a case study. This aquifer, that is exploited for human consumption and irrigation, is mainly fed by the effective infiltration from the ground surface and partly by the inflow from the carbonate aquifers bordering the valley. A numerical groundwater flow model has been developed through the finite difference MODFLOW2005 code and it has been calibrated and validated considering the recharge regime computed through a Thornthwaite-Mather infiltration model under the climate conditions observed in the period 1956-2012. Future scenarios (2010-2070) of temperature and precipitation have been obtained from three different GMCs_ ECHAM-5 (Max Planck Institute, Germany), PCM (National Centre Atmospheric Research) and CCSM3 (National Centre Atmospheric Research). Each scenario has been downscaled (DSC) to the data of temperature and precipitation collected in the baseline period 1960-1990 at the stations located in the study area through two different statistical techniques (linear rescaling and quantile mapping). Then, stochastic rainfall and temperature time series are generated through the Neyman-Scott Rectangular Pulses model (NSRP) for precipitation and the Fractionally Differenced ARIMA model (FARIMA) for temperature. Such a procedure has allowed to estimate, through the Thornthwaite-Mather model, the uncertainty related to the future scenarios of recharge to the aquifer. Finally, all the scenarios of recharge have been used as input to the groundwater flow model and the results have been evaluated in terms of the uncertainty on the computed aquifer heads and total budget. The main results have indicated that most of the uncertainty on the impact to the aquifer arise from the uncertainty on the first part of the processing chain GCM-DSC.

One of the goals of research in forest ecology is the development of simple indices as "proxies" in order to assess biological complexity in forests (e.g., structural and compositional diversity in forest stands). Many indices have been proposed to quantify forest stand diversity, but a general agreement on their use is yet not reached. Information theory and indices based on it are well-developed tools in ecological research and can respond to these requirements. In this short note, the recent literature on forest structural assessment is briefly summarized; then, one of the main properties of Shannon's entropy, namely the "recursivity", is proposed as a useful way for combining forest stand structure and species diversity into a single index. © 2013 © 2013 Taylor & Francis.

The Sentinel-1 mission will offer the opportunity to obtain C-band radar data characterized by short revisit time, thus allowing the generation of frequent soil moisture maps through the application of multitemporal retrieval algorithms. Exploiting the availability of some archived ERS SAR data with a short revisit time, this paper compares the estimates obtained by applying a multitemporal algorithm, developed in a previous work, to moisture provided by a land surface model and in situ data, as well as to soil moisture products derived from low resolution satellite data (ASCAT and SMOS). Results indicate the multitemporal algorithm produces soil moisture estimates that agree with model and in situ data at watershed scale. At finer scale, SAR presents better performances than other satellite instruments when compared to in situ data, although the correlation is not very high.

Although there are clear economic and environmental incentives for producing. energy from solar and wind power, there can be local opposition to their installation due to their impact upon the landscape. To date, no international guidelines exist to guide quantitative visual impact assessment of these facilities, making the planning process somewhat subjective. In this paper we demonstrate the development of a method and an Open Source GIS tool to quantitatively assess the visual impact of these facilities using line-of-site techniques. The methods here build upon previous studies by (i) more accurately representing the shape of energy producing facilities, (ii) taking into account the distortion of the perceived shape and size of facilities caused by the location of the observer, (iii) calculating the possible obscuring of facilities caused by terrain morphology and (iv) allowing the combination of various facilities to more accurately represent the landscape. The tool has been applied to real and synthetic case studies and compared to recently published results from other models, and demonstrates an improvement in accuracy of the calculated visual impact of facilities. The tool is named r.wind.sun and is freely available from GRASS GIS AddOns. (C) 2014 Elsevier Inc All rights reserved.

Flood estimation and flood management have traditionally been the domain of hydrologists, water resources engineers and statisticians, and disciplinary approaches abound. Dominant views have been shaped; one example is the catchment perspective_ floods are formed and influenced by the interaction of local, catchment-specific characteristics, such as meteorology, topography and geology. These traditional views have been beneficial, but they have a narrow framing. In this paper we contrast traditional views with broader perspectives that are emerging from an improved understanding of the climatic context of floods. We come to the following conclusions_ (1) extending the traditional system boundaries (local catchment, recent decades, hydrological/hydraulic processes) opens up exciting possibilities for better understanding and improved tools for flood risk assessment and management. (2) Statistical approaches in flood estimation need to be complemented by the search for the causal mechanisms and dominant processes in the atmosphere, catchment and river system that leave their fingerprints on flood characteristics. (3) Natural climate variability leads to time-varying flood characteristics, and this variation may be partially quantifiable and predictable, with the perspective of dynamic, climate-informed flood risk management. (4) Efforts are needed to fully account for factors that contribute to changes in all three risk components (hazard, exposure, vulnerability) and to better understand the interactions between society and floods. (5) Given the global scale and societal importance, we call for the organization of an international multidisciplinary collaboration and data-sharing initiative to further understand the links between climate and flooding and to advance flood research. © Author(s) 2014.

Il presente capitolo descrive sinteticamente lo sta
to della situazione, della quantità e della qualità
,
delle risorse idriche in Italia e fornisce una valu
tazione dei maggiori impatti cui saranno soggette
tali risorse. Si sofferma sulle principali fonti d'
incertezza legate alle valutazioni di scenario,
descrive i sistemi di approvvigionamento e gli indi
catori utili a valutarli e fornisce un quadro delle
principali criticità dei settori idroesigenti. Dopo
aver descritto il sistema legislativo, istituziona
le e
di governance, pone attenzione su un elemento chiav
e delle politiche di adattamento_ la strategia
cosiddetta del mainstreaming, ossia del veicolare l
e misure di adattamento in modo integrato nelle
politiche settoriali più pertinenti e già esistenti
; questo vale, ovviamente per quelle sulle risorse
idriche, ma anche per quelle relative al rischio id
rogeologico, e per quelle energetiche e agricole.
D'altro canto, le misure di adattamento riguardanti
le risorse idriche sono, in effetti, di volta in
volta mirate a ridurre la vulnerabilità e/o la sens
ibilità dell'apparato socio-economico,
l'esposizione del sistema idrologico e/o incrementa
rne la capacità adattativa.
Nel capitolo sono poi illustrati alcuni esempi di g
estione delle risorse idriche considerando
possibili cambiamenti climatici e tipologie di misu
re di adattamento, ed è descritta a scopo
esemplificativo una proposta operativa di sistema d
i supporto alle decisioni per l'adattamento ai
cambiamenti climatici, utilizzabile via Web e basat
a su un'analisi multi-criteri.
Il capitolo si focalizza inoltre sulle complesse in
terazioni esistenti tra i cambiamenti climatici e i
fattori non direttamente dipendenti dal clima, in p
articolare quelli socio-economici, che fanno sì
che la valutazione degli impatti sia affetta da un'
incertezza la cui entità può essere in alcuni casi
molto elevata. Si evidenzia quindi il fatto che le
strategie e le misure di adattamento non potranno
che ispirarsi al principio precauzionale, nei limit
i delle conoscenze disponibili, in un'ottica di
minimizzazione dei rischi di un "cattivo adattament
o" (maladaptation) e dei possibili effetti
collaterali negativi, anche grazie all'adozione di
accurate procedure di previsione del clima futuro.
Allo stesso modo, è necessario che anche le politic
he legate direttamente o indirettamente a quelle
idriche siano valutate per la loro validità (o per
lo meno neutralità) rispetto alle necessità di
adattamento (climate proofing).
Infine, si rileva, che anche se fino a oggi l'adatt
amento ai cambiamenti climatici ha avuto una
scarsa rilevanza e di conseguenza la ricerca specif
ica è ancora poco sviluppata, esistono tuttavia
una vastissima letteratura e un'adeguata dotazione
di mezzi applicativi che possono essere
utilizzati quale riferimento per l'identificazione
di misure di adattamento, rifacendosi ai principi
della gestione integrata delle risorse idriche, che
richiedono solamente di essere rivisti in un'ottic
a
dinamica, basata su analisi di scenario e con una p
articolare attenzione alla gestione
dell'incertezza.

Abstract
In the minutes to weeks after a landslide trigger such as an earthquake or heavy ...
In the minutes to weeks after a landslide trigger such as an earthquake or heavy rain, tens to thousands of landslides may occur across a region, resulting in simultaneous blockages across the road network, which can impact recovery efforts. In this paper, we show the development, application and confrontation with observed data, of a model to semi-stochastically simulate triggered landslide events and their impact on road network topologies. In this model, "synthetic" triggered landslide event inventories are created by randomly selecting landslide sizes and shapes from already established statistical distributions. The landslides are then semi-randomly distributed over the region's road network, where they are more or less likely to land based on a landslide susceptibility map. The number, size and network impact of the road blockages is then calculated. This process is repeated in a Monte Carlo type simulation to assess a range of scenarios. Due to the generally applicable statistical distributions used to create the synthetic triggered landslide event inventories and the relatively minimal data requirements to run the model, the model is theoretically applicable to many regions of the world where triggered landslide events occur. Current work focuses on applying the model to two regions_ (i) the Collazzone basin (79 km2) in Central Italy where 422 landslides were triggered by rapid snowmelt in January 1997, (ii) the Oat Mountain quadrangle (155 km2) in California, USA, where 1,350 landslides were triggered by the Northridge Earthquake (M = 6.7) in January 1994. When appropriate adjustments are made to susceptibility in the immediate vicinity of the roads, model results match reasonably well observations. In Collazzone (length of road = 153 km, landslide density = 5.2 landslides km-2), the median number of road blockages over 100 model runs was 5 (±2.5 s.d.), compared to the observed number of 5. In Northridge (length of road = 780 km, landslide density = 8.7 landslides km-2), the median number of road blockages over 100 model runs was 108 (±17.2 s.d.) compared to the observed number of 48. As model development progresses, we hope that this open source tool can be applied to other locations to aid civil protection agencies in exploring the potential impact to the road network of triggered landslide events.

Landslides play an important role in landscapes evolution and landforms shaping, and are a
widespread natural hazard in many areas of the World. Due to the large range of types, sizes,
and velocities of landslides, and to the complexity of their underlying physical processes,
many methods exist for mapping landslides and for studying their spatial distribution as a
function of the local geological setting.
The work begins with a critical review of the literature, aiming at reviewing the methods used
for landslide mapping, including aerial photo-interpretation (API), field mapping, LiDAR
derived images, and satellite images. Next, I analyse landslide inventory maps that I prepared
through the visual interpretation of aerial photographs, field survey and visual inspection of
LiDAR derived images, and I discuss problems associated to different methods for landslide
data collection. I further compare traditional field based event inventories to event inventories
obtained by exploiting new technologies and modern remote sensing data. Next, I evaluate
the applicability of LiDAR derived images for historical landslide and event landslide
inventory in densely forested, tropical areas, where other remote sensing data fail to provide
detailed landslide information. Next, I prepare an historical landslide inventory that I
compare to maps prepared by other interpreters with different experiences and backgrounds.
I present three new indices for comparing landslide inventory maps in terms of landslide
position, size, and geometrical agreement, at the scale of the single landslides. Use of the
indices opens to the possibility of improved assessments of the quality of landslide inventory
maps. Next, I present a method for obtaining and interpolating geological bedding attitude
data from API, and I use the results to measure the influence of bedding attitude on landslide
abundance and type.
I conclude by drawing general considerations on the production of landslide inventory maps,
and on their quantitative comparison, and on the quantitative assessment of the influence of
bedding attitude on landslides abundance and types. The conclusions are drawn based on a
research carried out mostly in study areas of south and in central Italy, and partly in a forested
area in Malaysia. The lessons learned in these areas can be applied in similar physiographic
and climatic regions.

Climate change in the Greater Alpine Region is seriously affecting permafrost distribution, with relevant consequences
on slope stability. In the Italian Alps, the number of failures from rockwalls at high elevation markedly
increased in the last 20-30 years_ the consistent temperature increase, which warmed twice than the global average,
may have seriously influenced slope stability, in terms of glaciers retreat and permafrost degradation. Moreover,
the growing number of tourists and activities in alpine regions (in particular in the Dolomites) made these areas
particularly critical in relation to natural hazards. In this light, an integrated short-term geomorphological and
climatic analysis was performed, in order to better comprehend the impact of main climate elements (especially
temperature and precipitation) on slope failures in high mountain areas.
In this contribution, we focus on three recent slope failures occurred at high elevation sites in the Dolomites (Northeastern
Italian Alps), declared a UNESCO World Heritage Site in August 2009. We describe here three important
rock falls occurred in the autumn 2013_ 1) the Sorapiss rock fall, on 30 September 2013; 2) the Monte Civetta rock
fall, on 16 November 2013; 3) the Monte Antelao rock fall, on 22 November 2013. The Monte Civetta rock fall
damaged some climbing routes, while the other two landslides did not cause any damage or injury. Despite the
limited volume involved, these three events represent an important warning sign in the context of ongoing climate
change.
Geomorphological information about the rock fall sites were combined with the climatic data acquired from the
meteorological stations surrounding the slope failure areas. A short-term climatic analysis was performed, with the
aim of understanding the role of the main climatic elements in the triggering of natural instability events in this
area and in the Alps in general.

Many shallow landslides in Taiwan are triggered by typhoons (tropical cyclones) during the summer months.
Each typhoon produces a different rainfall distribution, depending on its track and position and the atmospheric
conditions. This study investigated whether the additional rainfall data in a landslide susceptibility model can im-
prove its performance in predicting typhoon-triggered landslides, and whether information on past typhoon
events, combined with an event-based landslide inventory, can help predict landslides triggered by a typhoon.
To answer these questions, the study adopted a method that integrates rainfall data with the critical rainfall
model (a landslide susceptibility model based on geoenvironmental factors) to derive a logistic regression
model for predicting landslide occurrence. Results of a back analysis of landslides triggered by nine typhoons
from 2001 to 2009 reveal that, by including rainfall data, the integrated method performs better than the critical
rainfall model in the average overall accuracy rate (0.78 vs. 0.45) and the average modified success rate (0.75 vs.
0.68). Our preliminary results also suggest that it is possible to predict landslides triggered by a typhoon by using
a catch-all model developed from all other typhoon events in an inventory, or a group model developed from
other typhoon events of similar rainfall characteristics in an inventory. This study opens up a new research direc-
tion in analyzing rainfall-triggered landslides in Taiwan and elsewhere.

Landslide mapping is important for emergency management and landslide risk assessment. In this study, we propose a new mapping method, which combines the spectral signal contained in a satellite image and the geoenvironmental information included in a landslide susceptibility map. The image analysis captures areas with spectral signatures of event landslides in the image, while the landslide susceptibility map filters sub-areas, which do not have landslide prone conditions. The method assigns to every pixel of the satellite image a combined probability of landslide presence. We mapped typhoon-triggered landslides in southern Taiwan using the method. To compare with a landslide inventory prepared from orthophotos, we converted the probability map to a binary map of landslides and landslide free areas. Map comparison resulted in an overall accuracy of 0.93, an area percentage of overlapped landslides of 0.84, a modified success rate of 0.89, and a kappa statistic of 0.73. The method is fast, flexible, and relatively easy to use, and the probability map the method produces is useful by itself. We expect that the method can facilitate the rapid production of event landslide inventory maps, which in turn can assist emergency management. © 2014 Elsevier B.V. All rights reserved.

In this work, we combined multi-scale geological maps of Mercury to produce a new
global map where geological units are classified based on albedo, crater density and morphological
relationships with other units. To create this map, we used the 250 m/pixel mosaic of images
acquired by the narrow- and wide-angle cameras onboard the MErcury Surface, Space ENviron-
ment, GEochemistry, and Ranging (MESSENGER) spacecraft during its orbital phase. The geo-
logical mapping is supported by digital terrain model data and surface mineralogical variation
from the global mosaic of MESSENGER Mercury Atmospheric and Surface Composition Spec-
trometer observations. This map comprises the global-scale intercrater plains, smooth plains and
Odin-type units as reported in previous studies, as well as units we term bright intercrater plains,
Caloris rough ejecta and dark material deposits. We mapped a portion of the Raditladi quadrangle
(19-358N, 106-1338E) at a regional scale at a resolution of 166 m/pixel. We characterized the
geological context of the area and evaluated the stratigraphic relationships between the units. To
obtain a representative geological section, we analysed and corrected available topographical
data. The geological cross-section derived from our regional mapping suggests that volcanic
emplacement of Raditladi's inner plains followed the topography of the basin after the deposition
of impact-related units (i.e. melts, breccias and rim collapse) and was driven by low-viscosity
flows. Hollows that appear on Raditladi's peak ring were possibly formed from low-reflectance
intercrater plains materials exposed through the peak ring unit.

Floods are one of the most dangerous natural hazards in Mediterranean regions. Flood forecasting tools and early warning systems can be very beneficial to reducing flood risk. Event-based rainfall-runoff models are frequently employed for operational flood forecasting purposes because of their simplicity and the reduced number of parameters involved with respect to continuous models. However, the advantages related to the reduced parameterization oppose to the need of a correct initialization of the model, especially in areas characterized by strong climate seasonality. In this case, the use of continuous models could be desirable but it is very problematic in poorly gauged areas where continuous rainfall and temperature data are not available. This paper introduces a Simplified Continuous Rainfall-Runoff model (SCRRM), which uses globally available soil moisture retrievals to identify the initial wetness condition of the catchment, and, only event rainfall data to simulate discharge hydrographs. The model calibration involves only three parameters. For soil moisture, besides in situ data, satellite products from the Advanced SCATterometer (ASCAT) and the Advanced Microwave Scanning Radiometer for Earth observation (AMSR-E) sensors were employed. Additionally, the ERA-Land reanalysis soil moisture product of the European Centre for Medium-Range Weather Forecasting (ECMWF) was used.
SCRRM was tested in the small catchment of the Rafina River, 109 km2, located in the eastern Attica region, Greece. Specifically, sixteen recorded rainfall-runoff events were simulated by considering the different indicators for the estimation of the initial soil moisture conditions from in situ, satellite and reanalysis data. By comparing the performance of the different soil moisture products, we conclude that_ (i) all global indicators allow for a fairly good reproduction of the selected flood events, providing much better results than those obtained from setting constant initial conditions; (ii) the use of all the indicators yields similar results when compared with a standard continuous simulation approach that, however, is more data demanding; (iii) SCRRM is robust since it shows good performances in validation for a significant flood event that occurred on February 2013 (after calibrating the model for small to medium flood events). Due to the wide diffusion of globally available soil moisture retrievals and the limited number of parameters used, the proposed modelling approach is very suitable for runoff prediction in poorly gauged areas. © 2014 Author(s).

The theoretical development and practical application of three new methods for estimating the entropy parameter M used within the framework of the entropy method proposed by Chiu in the 1980s as a valid alternative to the velocity-area method for measuring the discharge in a river is here illustrated. The first method is based on reproducing the cumulative velocity distribution function associated with a flood event and requires measurements regarding the entire cross-section, whereas, in the second and third method, the estimate of M is based on reproducing the cross-sectional mean velocity (U) over bar by following two different procedures. Both of them rely on the entropy parameter M alone and look for that value of M that brings two different estimates of (U) over bar, obtained by using two different M-dependent-approaches, as close as possible. From an operational viewpoint, the acquisition of velocity data becomes increasingly simplified going from the first to the third approach, which uses only one surface velocity measurement. The procedures proposed are applied in a case study based on the Ponte Nuovo hydrometric station on the Tiber River in central Italy.

Considering a large satellite dataset (i.e. ~. 16. years of ERS-2 and ENVISAT observations) we investigate the reliability of remotely-sensed data for calibrating a quasi-two dimensional (quasi-2D) hydraulic model of a ~. 140. km reach of the middle-lower portion of the Po river (Northern Italy), for which detailed topographical information and in-situ hydrometric data are available. In particular, we refer to traditional and remotely-sensed hydrometric data for_ 1) evaluating if ERS-2 and ENVISAT data can be used for model calibration; 2) assessing whether remotely-sensed water elevation data can integrate traditional hydrometric data and improve the reliability of the hydraulic model. Satellite overpasses are generally characterized by low frequencies and the accuracy of remotely-sensed water surface levels is still limited. Nevertheless, the results of our analysis indicate that for medium-to-large rivers ERS-2 and ENVISAT satellite data can effectively enhance our knowledge of the average streamflow regime of a given reach_ they can be directly used in calibration, and their integration with in-situ data may significantly enhance the representation of the hydraulic behaviour of the study river. Considering our study reach, if compared to the model implemented on the basis of in-situ data only the hydraulic model parameterized on the basis of satellite and in-situ hydrometric data provides a better reproduction of average flow conditions, and it also results in the most accurate representation of the maximum water profile observed during a major flood occurred in October 2000. © 2014 Elsevier Inc.

A large number of dams were built in Italy in the first decades of the last
century to supply the need of industrial, electric power, agricultural and drinking
purposes. Among them, the Montedoglio dam, an important reservoir on the Tiber River
located in central Italy, with a drainage area of 276 km2 and a maximum storage volume
of about 153 Mm3. The dam is an earth-fill structure with overfall spillway partly
controlled by two sluice gates. On 29th December, 2010 due to the partial sudden collapse
of the spillway a huge water volume flooded the valley below the dam with high damage
for the territory and population, luckily without causalities.
Considering that scarce data are available for this type of events worldwide, this paper
aims, on the one hand, to illustrate the collected data of the event in terms of reservoir
levels, discharge hydrograph observed at downstream gauged river sites and flooded
valley area, on the other hand, to simulate the breach evolution and the downstream
propagation of the outflow. Considering the Nash-Sutcliffe performance measure in
simulation of the recorded reservoir levels, the time of breach formation and the
corresponding discharge coefficient are obtained through an optimization procedure and
values of 0.02 h and 0.15 are found, respectively. Finally, the Manning's roughness
coefficients for the downstream main channel and the floodplain areas are detected
through a methodology based on one-dimensional hydraulic modelling by considering
different flooding scenarios of valley.

The Rating Curve Model (RCM) proposed by Moramarco et al. (2005) is modified here for a
flood forecasting purpose without using rainfall information. RCM is a simple approach for discharge
assessment at a river site of interest based on relating the local recorded stage and the remote discharge
monitored at an upstream gauged river site located some distance away.
The proposed forecast model for Real-Time application, named RCM-RT, involves only two parameters
and can be used for river reaches where significant lateral flows can occur. The forecast lead-time
depends on the mean wave travel time of the reach.
The model is found accurate for a long reach of the Po River (northern Italy) and for two branches of the
Tiber River (central Italy) characterized by different intermediate drainage areas and wave travel times.
Moreover, the assessment of the forecast uncertainty coming from the model parameters is investigated
by performing a Monte Carlo Simulation.
Finally, the model capability to accurately forecast the exceedance of fixed hydrometric thresholds is
analysed.

A physically based simplified discharge routing method, namely, the variable parameter Muskingum discharge-hydrograph (VPMD) routing method, having the capability of estimating the stage hydrographs simultaneously in channels with floodplains is presented herein. The upstream discharge hydrograph is routed using this VPMD method in different two-stage symmetrical trapezoidal compound cross section channel reaches. The performance of the VPMD method is evaluated by numerical experiments using the benchmark MIKE11 hydrodynamic model and the field data of the Tiber River in central Italy. The proposed method is capable of accurately routing the discharge hydrographs, corresponding stage hydrographs and synthesizing the normal rating curves at any downstream ungauged river site which is not affected by any downstream effects. This study can be helpful for various planning and management of river water resources in both the diagnostic and prognostic modes. © 2014 Springer Science+Business Media Dordrecht.

Rainfall runoff (RR) models are fundamental tools for reducing flood hazards. Although several studies have highlighted the potential of soil moisture (SM) observations to improve flood modelling, much research has still to be done for fully exploiting the evident connection between SM and runoff. As a way of example, improving the quality of forcing data, i.e. rainfall observations, may have a great benefit in flood simulation. Such data are the main hydrological forcing of classical RR models but may suffer from poor quality and record interruption issues. This study explores the potential of using SM observations to improve rainfall observations and set a reliable initial wetness condition of the catchment for improving the capability in flood modelling. In particular, a RR model, which incorporates SM for its initialization, and an algorithm for rainfall estimation from SM observations are coupled using a simple integration method. The study carried out at the Valescure experimental catchment (France) demonstrates the high information content retained by SM for RR transformation, thus giving new possibilities for improving hydrological applications. Results show that an appropriate configuration of the two models allows obtaining improvement in flood simulation up to 15% in mean and 34% in median Nash Sutcliffe performances as well as a reduction of the median error in volume and on peak discharge of about 30% and 15%, respectively.
