Abstract
The basin of Gran valley is considered as one of dry valleys in Aljazeera district that belongs to Hit municipality 180 km west Baghdad. Area unit was conformed from some measured quantitative properties. Geomorphological and morphometric properties was used to construct data base relied on topographical maps, satellite image and DEM. Basin topography was studied. These landforms were parted into topological, erosional, sedimentary and carstic origins forms. Furthermore, morphometric properties represented the relationships among factors, corrosion processes and terrestrial phenomena such as area, forms, topography and aquatic drain net. Moreover, longitudinal, cross- sections and natural factors were associated. Results revealed that area of basin was 91.41 km2 which its water flew in Euphrates. The basin was very meandering semi-oval shape. Its river levels were 4 with 121 courses that possessed overall length of 149.7 km.
