Spatial Analysis to Estimate Runaff Using Scs (CN) to Wadi Al mur Watershed North of Iraq

The study aims at analyzing spatial and DEM data by the use of ArcGis, WMS, Global Mapper, Erdas programas for finding hydrological Such as climate soil components have been analysed ,in addition to classification utilization covering. present concludes American conservation Service hypothesis SCS) which is known Curve Number (CN)through integrating Remote Sensing (RS)technigue GIS evaluate water flow rate (QV) times rainfall (40185278 m3/ per – year).Implementing this model shows that basin Wadi Almur has such conditions help in generating clue rise of(CN)value when isabout (81,86).
