Abstract: During the previous periods, the water bodies and the topography of the surrounding lands were studied through the use of manual ground survey techniques which require many efforts and high cost in addition to the long time for the purpose of completion. Following the development of the science of remote sensing and GIS techniques and their use in the field of hydrological studies, work has begun on the use of computer technologies to conduct these studies with high accuracy. With DEM techniques, which are used to study topography of the ground, to identify stereoscopic digital models and to analyze the morphologic characteristics easily, quickly and at low cost. It was found that the land around Lake Sawa is a crumbling and undulating terrain with elevations range from 14 meters to 26 meters, also the study revealed that most surrounding land are composed of Gypsum rocks.
