The master's thesis in the Department of Geography - College of Education for Humanities - University of Basra, searched for "Hydrologic implications of the main morphometric parameters of the Ghadirah Al-Adhbi basin in Basra Governorate using Geographic Information Systems (GIS)".
The thesis presented by the student (Masara Ghaleb Majeed) aimed to study the morphometric and hydrological characteristics of the **Ghadirah Al-Adhbi** basin, as it is one of the dry basins that have not been fully studied, where Geographic Information Systems (GIS) and Digital Elevation Models (DEM) techniques were used to analyze these characteristics. The focus was also on the effect of natural factors such as terrain, soil and climate on surface runoff and determining the climatic water balance of the basin.
The thesis included an analysis of the morphometric parameters of the basin and the drainage network, in addition to studying the characteristics of surface runoff using the Berkeley and (SCS-CN) methods. Statistical analysis was also employed through the Pearson correlation coefficient to understand the relationship between morphometric and hydrological variables and their impact on the hydrological system.
The thesis concluded that the basin area is the most influential factor on its hydrological characteristics, and the SCS-CN method showed higher accuracy in estimating surface runoff compared to the Berkeley method. It was also shown that the high concentration time reflects the effect of topography and large area in regulating the runoff, while the statistical relationships revealed a clear effect of morphometric variables on the hydrological behavior of dry basins.
