Using the Technique of Geographic Information Systems and Remote Sensing to Estimate Surface Water Runoff of Basins in the Eastern Part of Diyala Province (An Extracted M.A Paper)

Abstract

This study deals with estimating the quantification of surface water runoff of basins, in the eastern part of Diyala province, using the technique of geographic information systems and remote sensing. In this part, there is a group of seasonal flowing valley. Its area is (14666.1). These valleys flow from the Highland mountains inside the Iranian territory towards Iraqi lands down to the downstream area till Hor Al-Shwejahis. There is no benefit of its waters, except for few, in the process of agriculture inside those valleys, especially those valleys are subject to big floods in winter which cause much destruction to villages in the valleys without protective devices. A clear instance is that of lingering effects of floods in 2015 on Mindili and Qasaniah villages. Hence, this research focuses on the process of estimating the size of surface water runoff of those valleys using (SCS-CN) technique belonging to the maintenance of American soil depending on the highest intensity of rain showers daily for 21 years. This technique requires a database containing classification of land cover and the previous case for soil moisture and soil hydrological groups prevalent in the valleys. After these data were extracted, the size of the surface water runoff of the study area (3071, 8, 3277, 85, 2710, 57) million/m3 was estimated for (Khanaqin, Ilam and Kermanshah). This value indicates that the basin of the study area has large amounts of running water that must be used and stored inside the basin to make use of it in the development projects that increase the efficiency of the agricultural, industrial and domestic uses in addition to groundwater recharge.
