Runoff Estimation and Dam Selection Site in the Khur khur Watershed (KHW), Using (SCS-CN) Method and (GIS & RS) Techniques

Abstract The Soil Conservation Service Curve Number (SCS-CN) method was applied to calculate the runoff in Khur khur watershed (KHW) based on (GIS and RS) techniques. is located southeast of Iraqi Kurdistan region northeast Iraq foothill zone. total area (106.84) km 2 , fifth order, it meets Sirwan river. study aim speculate annual volume select dam site order harvest water from (KHW). research reached specific basic results; rate returns (14408514.23 m 3 ), a suitable location proposed that could be exploited surface runoff, with capacity approximately (14 million ).
