The study of river basins is one of the geomorphological studies that have received special attention by geomorphologists and hydrologists, as it represents an integrated geomorphological and hydrological unit in terms of the water network and its ranks, the speed of water flow and other characteristics between the geomorphological and geological characteristics of the water and its geological characteristics. The natural, which represents the natural medium that affects the drawing and defining of its dimensions and the characteristics of the flow in it. Today, morphometric studies take a special place because they combine geomorphological and hydrological studies. They are a link between them. They add accurate facts and information in the hydromorphological studies of water basins. Aqrah Mountain is located in Nineveh Governorate - Aqrah District - Nahla District and has two northern slopes and Jinan. And each of them has a network of water basins. The study targeted this basin area, which has an area of 809.4 km2.
