Abstract|ملخص البحث

The great demand for water in the Kingdom of Saudi Arabia as well as the lack of rain in most regions of the kingdom, which is called the dry regions, requires an urgent need for groundwater resources. It is necessary to explore it and estimate its quantity and behavior by using spatial analysis tools such as Geographic Information Systems (GIS) and specialized simulation and modeling programs like ModFlow software. The creation of geo-database and modeling of shallow groundwater provide useful information about the quantity and quality of water resources taking into account flood disaster risk and wastewater pollution of the main wadis (valleys and basins). The application of GIS and ModFlow software allow also help in the understanding of the possible interconnections between the flood on the surface and the seepage area taking into account the lithology of the main sedimentary rock and soil layers nearby the surface. This articles presents the results of an applied research project that describes the methods, developed within the Research Center of the College of Engineering of Salman bin Abdulaziz University, to model the behavior of groundwater taking into account the flood-prone areas on the surface, to estimate the quantity of water that might percolate into groundwater and propose the best locations for the hydraulic works needed on the main wadis. Based on the increasing volume of wastewater from the North West and South East of the study area, and by using GPS to quantify the water table and water quality in many shallow wells in this region, this article presents a methodology that might be useful for pollution forecasting, planning and management with the help of pollution hazard maps.
