Evaluation The Hydrogeological Conditions of The Unconfined Aquifer in The Area Located Between The AL-Sin and AL-Rous Rivers in the Syrian Coast

The research area is located in the Syrian coast between the Sin and Rous river. This research aims at studying the hydrogeological characteristics of the unconfined aquifer in the research area and evaluating the conditions of its placed. The research was based on a monitoring network consisting of 36 wells that penetrate the unconfined aquifer, and measurements continued during the period (October 2016 until September 2017). The unconfined groundwater depths in the research area range between 0.5-11.5 m, and sometimes during the drought period reach to 13.5 m, while it is close to the surface in the winter and up to 0.1m in some wells. The electrical conductivity ranges between 550-3700 μs/cm, increasing as we go west and reaching 9,000 μs/cm and more in the wells near the sea during the dry period. Groundwater levels Lower in the dry period to below sea level in near-shore wells, achieves the hydrodynamic conditions of the seawater intrusion.
