The study aimed at using GIS technology to study the characteristics of the best sites for the construction of dams in the inner basins of Hebron Governorate, which intersect with the Wadi Gaza basin. The study used natural and human standards in selecting the best sites for the construction of dams. The analysis of topographic surfaces was done using a set of integrated GIS software programs, such as (ArcGIS 10.1) and its extension (Arc Hydro 2.0) and “Google Earth” to derive some morphometric variables.
The study showed that the amount of water that is expected to be stored in the dams can water 11507 acres of irrigated uncovered tomatoes. The amount of water is estimated to reach 7 m/m3, and the contribution to the national economy is expected to reach about 30 million dollars annually. In the case of cauliflower cultivation, the quantity of the stored water will irrigate 18669 acres of land and will employ more than 1,500 the unemployed.
