Studying the mechanisms of selecting the perfect sites for water harvesting is of great importance for the area in which the basin of Wadi Kayfa is located, as it is located within the borders of the Iraqi Jazeera Badiat Al Jazeera-the desert along the northern side of the Euphrates- and its climatic conditions characterized by aridity.

The study is based on the American soil hypothesis (SCS-CN) to estimate the volume of surface flow by adopting a set of variables represented by Land cover sorts and hydrological soil types and dealing with them using ArcGIS 10.4.1 and 9.2 Erdas Imagine.

The (CN) values showed that there are (6) values for the Wadi Kaifa basin, which ranged between (77 - 91), and the most prevalent one was the value (90) because it occupies a percentage of (59.9%), wears the value (86) has the least prevalence to occupy just (0.6%) of the basin area.

Concerning the annual surface flow (QV), it recorded values ranging between (181400-21150800 m3), and then arriving at the suggestion of four perfect sites for the construction of dams for watersheds based on the topography of the area and the results of the (SCS-CN) method
