Estimation of Annual Water Income Using (SCS-CN) Method based RS-GIS for Wadi Abu Khashab Watershed-North of Iraq
Abstract
The Annual Water income for Wadi Abu Khashab watershed estimated as about(47.416 km2) by employing a set of software (ArcGIS, Erdas Imagine) using the US Soil Conservation Method (SCS-CN) and four different methods resulting in an average annual water flow rate of the four Techniques were (7,049,316 m3), based on the spatial data of the satellite (Landsat-8) with spatial accuracy (30) meters and for bands (7,5,3) respectively, which is dated (5-2-2016) for two methods, while two methods are based on the geological background based on the geological map, this is the first time that the four methods have been used together in one search to ensure accurate and scientific results, the soil cover was classified and the nature of its uses, the soil hydrology and the identification of its varieties, the quantities of Rainfall, and the determination of the Curve Numbers (CN).
