| Abstract |
Salt-water intrusion, induced by a growing demand for fresh water, has become a matter of crucial importance in the coastal areas of many countries in Western Asia. Simulation programmes can be used as tools for planning the sustainable withdrawal of fresh water from the coastal aquifers. Although numerical methods are available to model the density dependent fresh-water/salt-water systems, it is often useful to simplify the system, e.g. by assuming a sharp interface between fresh water and salt water. Based on this simplification, the SIM_COAST code was developed to simulate the time-dependent behaviour of coastal aquifer systems in porous rock on cross-sectional models. The code was used to calculate the behaviour of coastal aquifers for two cases in the Middle East. The recharge effect of a dam across the Wadi Ham near the city of Fujayrah (United Arab Emirates) was investigated. Simulation results of several future abstraction/infiltration scenarios demonstrated that sea water might be expected to cease to intrude or even to retreat. In the Lebanon, an intensely karstified aquifer that discharges from springs at the coast, as well as in submarine springs near Chekka, was investigated. If an equivalent porous medium is assumed, then the simulations demonstrated the annual sea-water intrusion in summer and flushing of the system in winter. They provided reliable estimations of possible abstraction rates. |
