This study is tackling the geomorphological features of West-Bank catchment areas of the following wadis; Natuf, Sarida, Qana, At-Tien, Az-Zomer, Massien and Abu-Nar. These wadis belong to Mediterranean basin. Also it involves catchment area of wadis (Al-Qilt, Al-’Uja, Na’ayymeh, Fasayel, Al-Far’a and Al-Malih) of Dead Sea basin. The Study focus on the morphometric characteristics of the wadis and their hydromorphological impacts. the study also defines the ideal sites of water reservoirs of the flood water and also hydrological planning of some areas to be able to use the flood water of the small wadis those whose quantity of water is not big enough to be held behinds dams in economical revenue such as wadis (Abu-Sidra, Az-Zawyeh, Jayyos and Al-Jarousheyeh). The water quantity for every dam site has been calculated according to the factors of rainfall variable, infiltration, evaporation, land use, vegetation cover and springs discharge. This study covers area of 3700Km2, and aims to reserve 42-102mm3 of water for domestic-, agricultural- and industrial uses.
