An integratvie survey to study the geomorphological forms of the Valley Tarjil Basin using (GIS, RS) techniques.

Abstract

Abstract

This study concluded with the surveying and analysis of the geomorphological forms of the Wadi Tarjil Basin using Geographic Information Systems (GIS) and Remote Sensing (RS) techniques, in addition to a comprehensive field survey of the basin. The study examined natural factors such as geological structure, climate, and vegetation cover, as well as analyzing morphometric characteristics. The basin was divided into four sub-basins, and through the application of statistical equations such as the elongation ratio, circularity ratio, and form factor, it was found that most of the sub-basins are close to a rectangular shape. Additionally, the study analyzed the geomorphological processes that affected the basin, such as weathering, erosion, and the resulting geomorphological forms.

Furthermore, the impact of human activities such as mining, dam construction, and road development on the basin's morphology was evaluated. The results showed that the geomorphological forms in the region resulted from the interaction of natural factors with human intervention, leading to significant changes in the basin's topography and forms. The study recommended the need to monitor human activities to reduce their negative impact on the environment, while emphasizing the importance of using GIS and RS techniques alongside field surveys in geomorphological studies.
