| Abstract | ||
| This study aimed to build data base of the morphometric properties in the Udhaim basin , through analyzing the digital elevation model ( DEM ) by using a model in a geographical information systems programs , which integrated together in order to obtain the morphometric variances & measurements. This is done to understand its hydrologic significances & consequently understanding the water movement on the surface of the base. The study depended on the data of the digital elevation model accurately 30 m while the results gave a good matching with the Satellite images. Moreover, the study shows that the form of the catchment's areas is closed to the triangle while the main basin does not close to that shape, so that it characterized by systematic flow increased in the spring time .Also it is noticed that there is uniformity in the form of the catchments areas due to the similarity in the geomorphic processes. | ||
