Runoff generation dynamics within a humid river basin
The present paper introduces an analytical approach for the description of the soil water balance and runoff production within a schematic river basin. The model is based on a stochastic…
Runoff thresholds in derived flood frequency distributions
In general, different mechanisms may be identified as responsible of runoff generation during ordinary events or extraordinary events at the basin scale. In a simplified scheme these mechanisms may be…
A stochastic approach for the description of the water balance dynamics in a river basin
The present paper introduces an analytical approach for the description of the soil water balance dynamics over a schematic river basin. The model is based on a stochastic differential equation…
Watershed influence on fluvial ecosystems: an integrated methodology for river water quality management
The EU Water Framework Directive 2000/ 60 (Integrated River Basin Management for Europe) establishes the importance of preserving water quality through policies applied at watershed level given the strong links…
The Olive Tree: a Paradigm for Drought Tolerance in Mediterranean Climates
Olive trees (Olea europaea L.) are commonly grown in the Mediterranean basin where prolonged droughts may occur during the vegetative period. This species has developed a series of physiological mechanisms,…
Flood Volume Estimation and Flood Mitigation: Adige river basin
In the present work, we describe an extended flood risk analysis carried out in the Adige River basin in Italy. The methodologies adopted were used in a comparative approach that…
Can the basin morphology alone provide an insight into floodplain delineation?
The present research was aimed to evaluate flooding exposure by exploiting the potential of morphological indices (e.g., drainage area, local slope, curvature, etc.). It was found that the areas exposed…
Reply to comment by S. Nadarajah on ‘‘Space-time modeling of soil moisture: Stochastic rainfall forcing with heterogeneous vegetation’’
The comment by Nadarajah focuses on the spatial correlation function of the rainfall forcing adopted in the theoretical analysis of the soil water balance addressed by Isham et al. and…
The olive tree: a paradigm for drought tolerance in Mediterranean climates
Olive tree (Olea europaea L.) is commonly grown in the Mediterranean basin where prolonged droughts may occur during the vegetative period. This species has developed a series of physiological mechanisms…
Peak runoff contributing area as hydrological signature of the probability distribution of floods
For the analysis of hydrological extremes and particularly in flood prediction, deeper investigation is needed on the relative effects of different hydrological processes acting at the basin scale in different…
Scaling characteristics of spatial patterns of soil moisture from distributed modelling
Characterizing the spatial dynamics of soil moisture fields is a key issue in hydrology, offering an avenue to improve our understanding of complex land surface–atmosphere interactions. In this paper, the…
THE FLOOD EXPOSURE OF THE ITALIAN TERRITORY THROUGH A GEOMORPHOLOGIC APPROACH
The objetive of the present research was the evaluation of the flood exposure of the Italian territory. For this reason, the national territory has been subdivided in national, interregional and…
Influence of climatic and soil factors on flood frequency distributions in Southern Italy
The flood frequency estimation in ungauged basins requires the development of innovative statistical tools aimed to improve the available techniques for risk assessment. This research is aimed to better understand…
On the spatial and temporal sampling of soil moisture fields
Recent work by Isham et al. and Rodrìguez-Iturbe et al. has characterized the space- time variability of soil moisture through its analytically derived covariance function which depends on soil properties,…
Space-time modeling of soil moisture: Stochastic rainfall forcing with heterogeneous vegetation
The present paper complements that of Isham et al. (2005), who introduced a space-time soil moisture model driven by stochastic space-time rainfall forcing with homogeneous vegetation and in the absence…
