Diffracting morphometric Intake Basin Valley Otap Eraluation Quality Waters Underway Therein

Abstract

This research included estimating the volume of superficial flow for the basin of Valley otak It is one of the seasonal valleys which depends on the fall of rain were the average of its water increases in winter. Valley otak lies in Kalar District in its South-East part of Kurdistan region in Iraq within the Administrative boarders of Sulimanya Governorate in North-East part of Iraq. It slops from mountain (Dara Khala) North-East of Kalar District, the total area of the basin is (63 km2) with length (19 km2). The quality of surface water has been studied to show its appropriateness for different usages by comparing it with international and Iraqi specifications. Also, the study of the risk of flowing in the basin depending on different standards for classifying the risks of basins represented by some morphometric aspects and some hydrological aspects it seems by using the classification of showing the grades of flowing risks that Sofee Ahmed had a high level of risk.
