The research aims to analyze the morphometric and hydrological characteristics of the river valley basins located in the west of the Sirwan River within the administrative boundaries of the Kalar district، which number (8) eight major valleys and their morphometric and hydrological evolution for the period (2000-2015)، and for the purpose of analyzing the relationship between the natural components And its impact on the morphometric and hydrological phenomena and the natural variables of those water basins، which contributed to the development and variation of the water basins in the study area. Geographical information systems programs were relied on to show the morphometric and hydrological components (the amount of running water) for the river basins، which are within The semi-arid climate range in the semi-mountainous region south of Sulaymaniyah Governorate of the Kurdistan Region of Iraq. As the program (Arcmap10.8@RS) and a topographic and hydrological map at a scale (1;2500) were used، as well as reliance on the US satellite images on (WWW.USGS.COM) of the type (LAND SAT8 Oli) on 9/18 2020، in addition to the (DEM M15) and (STREM M15) elevation file for the study area and then relying on the (ERDAS IMAGIN2014) program for the purpose of Producing Cartographic representation and geographical information base showing the seasonal and annual hydrological situation of these water basins، which will contribute to the development of study area.The study has come to some important conclusions to some important measures to enjoy the order of geographical information as much as the high level of representation of the morphomorphic and biological drawings of the country's subjects.also natural properties and climates have a direct effect on the morphometer and hydrometic properties of the Basin water, such as the branching and lengths of the Basin and the amount of water that has flowed. And according to the results of the Basin water symbiosis, the highest amount of flooding to the Basin water appears to be between (1.4- 3.5 m3/ch), And according to Berkley's co-ordination results, the annual amount of expected water flow in the Basin water will be near (2.6 billion/m3), the highest of which reaches (0.626) billion/m3 in the (Qalatopzan) basin and the lowest is (0.211 ) billion/m3 in the (Kawacharmo) basin.
