Abstract: : This research aims to analyze the morphogeomorphic characteristics of Al-Hawad valley within the arid cycle of erosion so as to curb its floods by prospecting agro-animal investment that will support into flood mitigation; by applying the morphometric analysis approach and GIS techniques. Al-Hawad valley runs across an area of 598 meters high and 359 meters low; characterized by a moderate ruggedness; a gentle slope of 1.28 m/km, a relative topography of 54.4 m/km; and a roughness value of 0.006; as well as a stability rate of 2.5 km2 for each 1 km, and a dense water drainage network with a dendritic drainage pattern. It also holds rank 5 at its entrance into the river Nile; and owns 789 watercourses; almost regular with large numbers of water courses concentrated in the first and second orders. The total length of channels for all ranks is 2947 km decreasing gradually from first rank to third rank; with an overall average height of 198 for all ranks; and the fourth rank owns the smallest length ratio followed by the second rank, while the largest length ratio was in the fifth rank. The average bifurcation ratio is 5.88 while the highest branching ratio is in the third rank. The basin area is 7476.33 km2 with a basin circumference value of 439 km of 178 km; the drainage density is 0.024; river frequency is 0.11; the texture of the basin is 1.8; shape facto is 0.24, rate of roundness is 0.04, and the elongation rate is 0.27. These Morphometry and geomorphic characteristics distinguish Wad-Al-Hawad within the arid cycle with predictions for becoming a source for water security and future governmental investment initiatives. Keywords: morphometric analysis, geomorphic analysis, erosion cycle, investment initiatives.
