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).
