Abstract
This Study Includes a geometrical Analysis of Wadi Al- jafer proposed in Shirqat district- north of Salah addin Government. In this work, to extract the geometrical elements, DEM with (10*10) m Pixels Arc GIS,Global Mapper and Software are utilized. These elements include a negative and positive (land) surface volume, negative and positive surface area, uneven area islands, water depth average and land thickness. In order to investigate the variation of these elements with each water level, the relationships between water level against each geometrical element are plotted. The results show that the reservoir volume of the proposed dam at level 185 m equals (941788 m3). The graph of negative surface area versus water level shows that the area will increase with a new added land within the reservoir boundaries. Also, it is found that maximum negative surface area is (228212 m2) whereas the max positive surface area which may immerged by reservoir is about (1845m2). Finally, the results also, reveal that the dam height at its maximum level is (12.25m) and the proposed dam width is about (211.1m).
