Geomorphological studies are concerned with the study of geomorphological processes and the different types of it in the study area, As the appropriate natural environment helped to activate the erosion processes and the formation of the topographic features and the content of the natural resources within an integrated environmental system may differ from neighboring systems,Whether in the ground systems and the contents of the rocky variation or forms of land or investment areas,Water erosion is one of the most widespread and most dangerous erosion inValley of river basins because of its role in the fragmentation of rocks and their erosion and lifting from the surface and then transported and deposited in places with different distances.As the falling rain water in the basin area suddenly contribute to a large part in the erosion process and deposition especially when rain falls during the short times and in a quick and powerful showers working to break up the rock particles and materials clastic soft on the slopes and cliffs, through the pressure caused by the collision of rain drops to those molecules Directly.As it represents a preliminary stage in the erosion processes, and this type of mechanical act has an important role in increasing the surface area of rock fragments resulting from the crash of the original rock, And its work is limited to the fragmentation of the rock and prepared in order to then transmitted by a factor of erosion.
