Geomorphology of Sabkha Al-Qasab, Using Geographical Information Systems and Remote Sensing

Sabkha Al-Qasab is one of the wasted natural and salt resources, which did not receive enough attention like other natural resources, so what is meant by reed Sabkha? The reed Sabkha is salt surfaces in areas of highly saline lakes. The salt surfaces are usually based on clay, silt, and sand, often covered with saline crusts, and the Sabkha form when the underground water level approaches the earth's surface. The importance of the research lies in explaining the importance of applying remote sensing techniques and geographic information systems in creating a digital database for Sabkha and determining the volumetric, morphological, and mineralogical characteristics of Sabkha sediments and their origin, intending to know the deposition environments and the stages they have gone through. The study relied on satellite visualizations, topographical maps, and field studies. The team used the objective, analytical, and historical method for conducting the survey in the Riyadh region in the Kingdom of Saudi Arabia. The study concluded by encouraging industries based on salt extraction, following up distributing the product to consumers, and emphasizing the necessity of implementing environmental laws by not throwing any waste so that the groundwater is not polluted.
