المستخلص: The aim of this study is to assess the hydro-morphometric and flow characteristics (include: morphology, analysis of drainage patterns, and drainage morphometry) and its influence on hydrology of Wadi Khumal Basin, North Saudi Arabia, which is considered as an additional strategic future water supply for ground water reservoirs and for planning rainwater harvesting and watershed management. For detailed study we used Shuttle Radar Topographic Mission (SRTM) data for preparing Digital Elevation Model (DEM), aspect grid and slope maps, Geographical information system (GIS) was used in evaluation of linear, areal and relief aspects of morphometric parameters. The study reveals that the triangular shape of the Wadi Khumal Basin is mainly due to the guiding effect of Scarp-Radwa Mountains and to many of the the thrusts, faults and dykes that appear in hard and massive metamorphic and igneous rocks which resists weathering processes to give that shape. Study adopted in hydrological analysis of the Khumal Basin on the model TR-55 to calculate storm runoff volume, peak rate of discharge, hydrographs, and storage volumes required for floodwater reservoirs, where a rainstorm were analyzed its 25 mm, Runoff hydrographs were constructed for four sub-basins of wadi Khumal.
