The lack of water resources in many regions is the main challenge for the\nhuman being and to extended investigations. Water resources controlling and\nmanagement is essential in the areas depending on the seasonal rainfall. This\nresearch aims to estimate the surface water runoff for Basin of Alrakhmah\nValley located in the southwestern part of Kirkuk Province in northeastern of\nIraq. Analyzing of Spatial data and Digital Elevation Model (DEM) data has\nbeen conducted using Geographic Information System (GIS) to estimate the\nhydrological properties for the watershed valley with 158.5 km2 surface area.\nThe results showed that watershed valley type is from the fifth rank with a\nlongitudinal shape and topography percentage of 0.568. The watershed textures\nfound to be 3.24 and the drain density 1.5 at 3.49 river branching. Finally,\nthe annual estimated surface water retreat according to the morpho-\nhydro climatic elements found to be 0.01286233 milliard cubic meter.
