Résumé
In arid environments, fresh water is a precious resource because of the limited rainfall and hot climate. The United Arab Emirates (UAE) has an arid environment, and so suffers from a lack of water sources on the Arabian Peninsula. The main source of water in the UAE is groundwater. However, an increase in population, agriculture and industrial activities in recent years has resulted in an increasing demand for water. In order to meet this increased demand for water, especially for safe drinking water, the UAE has constructed several desalination plants to convert seawater into fresh water, mostly along the coast of Abu Dhabi. Despite the huge volume of fresh water which can be produced by these plants, storage facilities would be inadequate in an emergency situation. Thus, the Liwa Aquifer Storage and Recovery (ASR) Project was developed in order to establish a reliable underground reservoir to store and recharge fresh water in the Liwa area, Abu Dhabi in 2008. Within the scope of the project, several pumping and observation wells were constructed in the North of the Liwa Oasis. During the project, pumping tests were conducted and many analysis and studies were performed in order to determine the hydraulic characteristics of the Liwa aquifer. The purpose of the current study is to develop a 2-D transient groundwater flow model of the Liwa Aquifer using data obtained from pumping tests in Scheme A to predict hydraulic properties with code MODFLOW in Groundwater Vistas.
