Présentation
Extreme events, such as severe storms, floods, and droughts are the main features characterizing the hydrological system of a region. In the West Bank, Palestine, which is characterized as arid to semi-arid region ; little work has been carried out concerning hydrological modeling. However some rainfall-runoff studies were done in the region using simple lumped models. The present research study deals with the hydrological modeling in Faria catchment under limited hydro-meteorological and spatial data. The goal has been to obtain reliable estimates of naturally available, surface water resources in arid to semi-arid environment of the West Bank, Palestine. For this purpose, an up to date physically-based and spatially distributed hydrological model (the newly coupled TRAIN-ZIN model) has been applied. Advances in geographical information system (GIS) made it possible to enhance the spatial model parameters estimation. Thus this study has been the first attempt of its kind in the Faria catchment which started from basic database development to adoptive model parameters identification and application. Understanding the processes of runoff generation is prerequisite to enhance the evaluation and quantification of water resources in the Faria catchment. Consequently such evaluation can be utilized in the development of best management practices that can be adopted to manage the scarce water resources in the catchment. The Faria catchment dominates the north eastern slopes of the West Bank and is a catchment of about 320 km2. It has arid to semi-arid characteristics with a Mediterranean climate which is characterized by hot and dry summers and mild and wet winters. The catchment receives a mean areal rainfall of 412 mm per annum falling during October to April. Rainfall events are highly variable in space and in time. Generally, they are of local extent with high intensities. Hence flood events of short duration occur mainly during winter months. Spring discharges are the direct contact between surface water and groundwater in the catchment. Wadi Faria is considered as a perennial Wadi since 11 springs provide the baseflow for the Wadi and preventing it from drying up during hot summers.
