Abstract
The aim of study is to analyze The Morphometric characteristics and hydrological network Watery discharge of Al-ibra valley, represented cadastral, and longitudinal, formal, and Topographic, characteristics of the water drainge network. as well as study indentify some hydrological variables such as concentration. as well as study The physical geographic factors which effect to geomorphologic processes and reflect it to the characteristics of morphomatric and hydrological . study relied on GIS, Topographic maps and digital elevation model (DEM), As a tool to set up a network rivers draining map.
