N2 - Regional groundwater models used for analyzing groundwater systems (infiltration-discharge relations) are often steady state and, therefore, need long-term average recharge input. On the other hand, the spatial variation in the recharge due to distributed land-use, soil type or texture, slope, groundwater level, meteorological conditions, etc., can be significant and should, therefore, be taken into account. Hence, WetSpass was developed as a physicallybased methodology for estimation of long-term average spatial patterns of surface runoff, actual evapotranspiration, and groundwater recharge. The model is especially suitable for studying effects of land-use changes on the water regime in a basin. The computer model was integrated in the GIS ArcView. Its set-up is extremely flexible; it allows easy new definition of natural or man-made land-use types. This paper describes the concept of the model and gives an example of a developed WetSpass recharge map for the Gaza Strip, Palestine.
