Abstract:
The present study aims to study the environment of Evaporation Al Asfar Lake, Al Hassa area, eastern province, Saudi Arabia. Remote sensing, sedimentological, hydrogeological, chemical studies and Geographical Information Systems (GIS) are implemented to achieve the objectives of this study. The processed landsat-5 TM and SPOT Imageries indicated, there is a general increment in both the sabkha and water ponds areas extent with the passage of time. The origin and the various sediments types are recognized through the sedimentological aspects of this study. Different sabkha grades are identified. These different sabkha grades have various degrees of salt content as it is indicated from the TDS spatial distribution at Al Asfar area. This study revealed that the surface water of Al Asfar lake is characterized by a relatively low salinity and then re-treating and reusing of this water in agricultural purposes will lead to minimize the sabkha extension, to mitigate its impact on the nearby farms of Al Hassa oasis, to mitigate aquifer recharge with high saline water and to optimize the water use of this available surface water body in this arid environment. The results of this study are important in any future development of this area of the Al Asfar and in planning of how to reuse the water lakes in the agricultural purposes. Chemical results are very important to be taken in consideration by Saudi Aramco, as the different sabkha grades have their various corrosion levels that may impact the pipelines crossing this sabkha area.
