The characterization of the spatial-temporal variability of soil moisture is of paramount importance in many scientific fields and operational applications. However, due to the high variability of soil moisture, its monitoring over large areas and for extended periods through in-situ point measurements is not straightforward. Usually, in the scientific literature, soil moisture variability has been investigated over short periods and in large areas or over long periods but in small areas. In this study, an effort to understanding soil moisture variability at catchment scale (> 100 km2), which is the size needed for some hydrological applications and for remote sensing validation analysis, is done. Specifically, measurements were carried out in two adjacent areas located in central Italy with extension of 178 and 242 km2 and over a period of 1 year (35 sampling days) with almost weekly frequency except for the summer period because of soil hardness. For each area, 46 sites were monitored and, for each site, 3 measurements were performed to obtain reliable soil moisture estimates. Soil moisture was measured with a portable Time Domain Reflectometer for a layer depth of 0-15 cm. A statistical and temporal stability analysis is employed to assess the space-time variability of soil moisture at local and catchment scale. Moreover, by comparing the results with those obtained in previous studies conducted in the same study area, a synthesis of soil moisture variability for a range of spatial scales, from few square metres to several square kilometres, is attempted. For the investigated area, the two main findings inferred are_ 1) the spatial variability of soil moisture increases with the area up to ~10 km2 and then remains quite constant with an average coefficient of variation equal to ~0.20; 2) regardless of the areal extension, the soil moisture exhibits temporal stability features and, hence, few measurements can be used to infer areal mean values with a good accuracy (determination coefficient higher than 0.88). These insights based on in-situ soil moisture observations corroborate the opportunity to use point information for the validation of coarse resolution satellite images. Moreover, the feasibility to use coarse resolution data for hydrological applications in small to medium sized catchments is confirmed.

Predicting the spatial and temporal occurrence of rainfall triggered landslides represents an important scientific and operational issue due to the high threat that they pose to human life and property. This study investigates the relationship between rainfall, soil moisture conditions and landslide movement by using recorded movements of a rock slope located in central Italy, the Torgiovannetto landslide. This landslide is a very large rock slide, threatening county and state roads. Data acquired by a network of extensometers and a meteorological station clearly indicate that the movements of the unstable wedge, first detected in 2003, are still proceeding and the alternate phases of quiescence and reactivation are associated with rainfall patterns. By using a multiple linear regression approach, the opening of the tension cracks (as recorded by the extensometers) as a function of rainfall and soil moisture conditions prior the occurrence of rainfall, are predicted for the period 2007-2009. Specifically, soil moisture indicators are obtained through the Soil Water Index, SWI, a product derived by the Advanced SCATterometer (ASCAT) on board the MetOp (Meteorological Operational) satellite and by an Antecedent Precipitation Index, API. Results indicate that the regression performance (in terms of correlation coefficient, r) significantly enhances if an indicator of the soil moisture conditions is included. Specifically, r is equal to 0.40 when only rainfall is used as a predictor variable and increases to r = 0.68 and r = 0.85 if the API and the SWI are used respectively. Therefore, the coarse spatial resolution (25 km) of satellite data notwithstanding, the ASCAT SWI is found to be very useful for the prediction of landslide movements on a local scale. These findings, although valid for a specific area, present new opportunities for the effective use of satellite-derived soil moisture estimates to improve landslide forecasting.

Soil Moisture (SM), being one of the main variables within the system that controls the hydrological interactions among soil, vegetation and atmosphere, plays a key role in the water cycle. Satellite systems, both active and passive, have already demonstrated their capability to provide reliable SM measurements. The European Space Agency (ESA) Soil Moisture and Ocean Salinity (SMOS) mission, launched in November 2009, was the first specific SM satellite mission. In this work we assessed the capability of SMOS data to accurately capture SM dynamics over a long time period by comparing them with in situ observations. To better assess the performance of such results, they were also compared with those obtained with alternative satellite-based SM products, considering in particular those generated by Advanced Microwave Sounding Radiometer (AMSR-E) and Advanced SCATterometer (ASCAT) data.

The monitoring of soil moisture (SM) can be performed through remote sensing technologies. Among the operational microwave radiometers potentially able to provide information about SM and its variability in the space-time domain, in this work the capability of the AMSU (Advanced Microwave Sounding Unit) sensor has been investigated. In particular, SM information, achieved implementing two different AMSU-based indices, has been compared with both in situ measured and modeled observations for several sites spread out all over Italy. The results indicate that the AMSU sensor can be considered as a useful tool to provide quite reliable information about SM variability, mainly if its high temporal resolution is taken into account.

In this study, the feasibility of the resistivity method for the study of the spatial and temporal soil moisture variations in the Vallaccia catchment (central Italy), covering an area of about 56km 2, was investigated. Correlation and regression analyses were performed over a 1year data set of simultaneous soil electrical resistivity and soil moisture measurements, acquired in eight different sites with a Resistivimeter Syscal Junior and a portable Time Domain Reflectometer (TDR), respectively. Measurements acquired in-time by continuous Frequency Domain Reflectometer (FDR) sensors were also used and compared with simultaneous resistivity measurements. The statistical analyses were conducted not only for the whole data set, but also separately for each sampling day, for each sampling site and considering spatially averaged data. Results showed a good correlation between resistivity and soil moisture measurements, revealing the capability of resistivity measurements to infer soil moisture spatial and temporal variability with a root mean square error equal, on average, to 4.4% vol/vol. In comparison with TDR, the resistivity method gives information integrated on a greater volume of soil and the measurements are easier and quicker to be carried out. Therefore, this method can be considered as an alternative tool to be employed for qualitative and quantitative soil moisture monitoring in small to medium catchments.

Ai fini di migliorare la conoscenza della distribuzione territoriale e della dinamica temporale della falda ipodermica anche nel 2011-2012 è proseguita l'acquisizione dei della rete piezometrica regionale. Nell'arco dei tre anni del contratto l'acquisizione, e la successiva elaborazione, dei dati è avvenuta in quattro fasi_
Fase 1): nel 2009 sono stati eleborati preliminarmente le misure del livello di falda dal 1997 al 2008 in 157 siti per un totale di 21,470 letture.
Su un numero ristretto di siti piezomentrici caratterizzati da una buona continuità temporale delle letture, sono state approfondite le relazioni fra la dinamica temporale della falda ipodermica e altre variabili ambientali.
Infine, sono stati prodotti documenti cartografici relativi alla profondità di falda in determinati momenti dell'anno, attraverso elaborazioni statistiche e geostatistiche.
I risultati del lavoro sono stati presentati nel rapporto 1.1 del 2009.
Fase 2): nel 2010 sono stati considerati tutti i piezometri disponibili nella pianura per i quali fossero disponibili letture affidabili e con buona continuità temporale nell'intervallo temporale 2004-2009. Sono stati selezionati 153 siti piezometrici, per un totale di 13323 letture. Sono state inoltre acquisiti i dati relativi alle variabili climatiche, precipitazioni, P, temperature, T, ed evapotraspirazione, ET, per tutti i siti considerati. I risultati del lavoro sono stati presentati nel rapporto 2.1 del 2010
Fase 3): nel 2011 sono state acquisite le letture relative a tutta la rete piezometrica regionale per il 2010 al fine di validare il modello di previsione del livello di falda su una serie temporale di dati relativi ad un arco temporale non considerato nella calibrazione del modello stesso e per produrre carte del livello di falda per tutto il territorio di pianura con cadenza mensile.
Fase 4): nel 2012 sono state acquisite le letture relative a tutta la rete piezometrica regionale attiva nel 2011 al fine di_ 1) continuare la la validazione delle formule di previsione del livello di falda, tramite l'utilizzo delle letture disponibili per il 2011 per i siti di validazione, o parte di questi, già selezionati nel 2010; 2) migliorare gli algoritmi di stima del dato di falda a livello puntuale (singoli siti) con particolare attenzione a quelli delle province di Bologna e Ferrara al fine di un'eventuale implementazione in Irrinet; 3) valutare l'utilizzo di letture manuali maggiormente distanziate nel tempo rispetto alle attuali, ai fini di ottimizzare la sostenibilità economica della rete di monitoraggio

Soil sealing is one of the major threats to soil, leading to a virtually permanent loss of soil functions. Beside the loss of fertile soils with a direct impact on food security, soil sealing strongly modifies the hydrological cycle. This causes an increased flooding risk, due to urban development in potential risk areas and to the increased volumes of runoff. Soil hydrological properties, their distribution and variability are then critical issues when adopting hydrological models at catchment scale.
In a densely populated area of Northern Italy, the impact of soil sealing due to urban development has been assessed using a distributed infiltration model in different land use scenarios, representing the sealing conditions in 1976 and 2008. The soil hydrological properties have been derived from the Emilia Romagna soil data base (ca. 3300 soil sites) using a locally validated set of PTFs, The spatial variability has been explicitly taken into account adopting a SCORPAN kriging approach based on the soil mapping units at 1_50,000 scale and on major land use. The lower boundary conditions have been set assuming the depth of impermeable horizon within 100 cm or the 95th percentile of the shallow groundwater depth. Peak discharges have been considered for 20 and 200 yr rainfall events. The impact of land use changes under the different simulation scenarios is discussed in terms of their impact on soil hydrologic functions.

According to the Italian Legislative Decree 152/06 of April 3rd, 2006, concerning the consolidated law governing environmental issues ("Testo Unico recante le Norme in Materia Ambientale"), the
Contamination Threshold Value is defined as follows (art. 240, comma 1, letter b): "threshold values are the values of contamination of environmental matrix above which the characterization and specific risk
analysis of the contaminated site, as described in the Appendix 5 at part four of the present law, becomes necessary. In the event the potentially polluted site is located in an area where geogenic or
anthropogenic factors are responsible for exceeding the threshold values for some parameters, the background content of these parameters is assumed as threshold."
In the last decades the increase of industrial activities and the massive use of pesticides in agriculture, enhanced the risk of soil contamination by pollutants. Among these, heavy metals, due
to their persistence, accumulate in soils possibly reaching concentrations above regulatory contamination thresholds. An accurate knowledge of the "usual" background content of metals in soils
is then necessary to assess their contamination state. Aim of this work is to map the concentration of topsoil heavy metals using a Scorpan Kriging approach. The approach combines the trend of
metals concentrations, as derived from the 1_50,000 soil map, with geostatistical modeling of the stochastic, locally varying but spatially correlated component. The trend component is described in
terms of varying local means, calculated accounting for soil pedo-geochemical affinity and dominant land use.

Understanding past sea-level change plays an important role in determining the underlying causes, and also allows the extrapolation of past sea levels to locations and epochs for which there are no instrumental data. A compilation of global sea-level estimates based on deep-sea oxygen isotope ratios at millennial-scale resolution or higher was published since '70. These global sea level curves do not take in account isostasy and tectonics.
Observed sea level change can be reconstructed from dated fossils, coral reef terraces, speleothems, emerged and forming terraces on coastal areas, archaeological and other markers well connected with sea level. Because of the lack of coral reefs in the Mediterranean sea, results on late Quaternary sea level changes have been difficult to obtain in comparison with typical sites such as Barbados, the Huon Peninsula, Tahiti, Florida and others. On the contrary the very low tidal range of Mediterranean seas offers a good opportunity to produce precise observations and considerations on climatic change.

The velocity-area method and entropy method for assessing with uncertainty discharge measurements at a gauged river site are analysed and compared; uncertainty is represented through the grey number technique. Two different approaches for greyfication of both the methods are presented. In the first approach, the uncertainty affecting each measurement used to estimate the discharge is characterized by a grey number_ all the grey uncertainty components are then combined through the grey mathematics. In the second approach, greyfication is applied to the relationship expressing the total uncertainty on the discharge measurement, provided by the EN ISO 748 guidelines.
Results of the application of the proposed methods to measurement data pertaining to a gauged Tiber river section show that the first greyfication approach leads to a larger discharge uncertainty estimate with respect to the latter. Furthermore, being the greyfication approach and the flow area quantification the same, the velocity-area and entropy methods provide nearly the same estimate of the uncertainty affecting the discharge measurements, i.e. the grey discharges they provide are fairly similar.

Abstract
A large number of dams were built in Italy in the first decades of the ...
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. The dam is an earthfill structure and the maximum regulation level, the maximum storage level and the crest level are 394.60, 396.30 and 398.30 m a.s.l., respectively. The water storage volume, with the water at the height of the spillway, is approximately 153x106 m3.
On December 29, 2010 due to a sudden spillway collapse a huge water volume flooded the valley below the dam with high damage for the territory and population.
This paper attempts to assess the discharge hydrograph following up the Montedoglio spillway collapse and its routing along the Tiber River valley. The analysis is based on the recorded water reservoir level during the catastrophic event. The mathematical modelling of the reservoir depletion and flood propagation allowed advancing well-founded hypotheses on the temporal evolution of the breach formation. Furthermore, using a one-dimensional model for flood wave propagation, the roughness calibration for the main channel and floodplains has been addressed.

This study presents an enhancement of the Rating Curve Model (RCM) proposed by Moramarco et al.
(2005) which was initially formulated to assess discharge at a downstream river site where only stage
is monitored while the flow is recorded at an upstream section and significant lateral inflow can occur
along the river branch. The original model formulation is here of fact extended for upstream discharge
estimate by assuming the flow known at a downstream site and stages measured at both ends. In this
new configuration, the model can be applied to river reaches with negligible lateral inflow or to river
reaches with significant lateral contribution but where a kinematic flow regime holds. The new model
formulation is tested by considering two case studies, both selected in the Upper-Middle Tiber River
basin, in central Italy. For the first case study, the model is applied to 22 flood events observed along three
branches of the Tiber River with accurate rating curves at ends and having the same upstream river site.
RCM successfully simulates the discharge hydrographs observed at the upstream section closely capturing
both the peak rate and the time to peak, with average absolute errors less than 5% and 0.36 h, respectively.
The model accuracy is found independent of the intermediate basin area and, hence, of the lateral
inflow contribution. The rating curve computed in this upstream section by using the shortest reach is
slightly overestimated whereas the ones derived by applying the model to the other two reaches are
almost coincident and slightly underestimated, but for all of them the errors are less than 5%.
The second case study concerns the estimation of the upstream rating curve at a river site, where discharge
measurements are available for very low stages alone, starting from the flow known at two different
downstream equipped sections. The RCM application to recorded flood events provides two very
similar stage-discharge relationships with a maximum difference, between the reproduced rating curves,
of about 5 m3/s for the higher stage values.
Moreover, the RCM accuracy is shown to be satisfactory for river reaches located in physiographic
regions (northern Italy and Slovak Republic) different from the one used for the model development
and testing and considered in the two case studies mentioned above.
Finally, the model capability to take implicitly account of the unsteady effects (i.e. rating loop) is shown
through experimental data recorded by an ultrasonic flowmeter at a gauged site of the Tiber River as well
as by considering a numerical test.

The paper reports interdisciplinary research of weathering profile stages on gneiss with regard to tectonic
and landscape evolutions of the western Sila Grande Massif (Southern Italy). The outcropping rocks consist
of medium- to coarse-grained biotite-garnet and sillimanite gneiss (BGS-G), and medium- to coarsegrained
biotite-muscovite migmatitic gneiss (M-G). The BGS-G rocks are fractured and weathered with
either massive or foliated texture, whereas the M-G rocks are intensely weathered and fractured with a massive
texture and frequent pegmatite veins. Petrographical and mineralogical variations show that both
gneissic rocks (BGS-G and M-G samples) underwent weathering processes characterized by a progressive
chemical attack on the labile minerals with generation of neoformed minerals and substitution of the original
rock fabric. The weathering processes produced phyllosilicates and Fe-oxides; neoformed clay minerals and
ferruginous products replaced feldspars and biotite during the most advanced weathering stage. Microfractures
and morphological variations occur on the original rock and, thereby, affect the surrounding landscape
processes. The weathering profile mineralogy and rock textures viewed in the context of landscape evolution
provide useful insights into the widespread slope movement phenomena in the Sila Grande Massif gneiss
