Abstract : The position of salt water-freshwater interface in coastal aquifers is analyzed. Governing partial differential equations are formulated by combining Darcy's Law and continuity equation and by using GhybenHerzberg Principle and Dupuit assumptions. For the solution of the governing equations Finite Difference Method is used. A computer program based on two-dimensional steady-state mathematical model is utilized. As sufficient and reliable field data are usually not available, the program is tested using two simplified flows for which analytical solutions are available or obtainable, namely, a one-dimensional flow in a strip aquifer with two different boundary conditions and an axi-symmetric radial flow in a circular aquifer. The results revealed that there is a .good agreement between analytical and numerical solutions. Finally, after sensitivity analysis and calibration, the model is applied to the lower valley of Wadi Hali on the coastal plain of Saudi Arabia. The application is intended to be an example of a management scheme. The results are discussed and some conclusions are drawn. Limitations of the model arise from the assumptions on which it is based. Therefore, the application of the model is limited to steady, twodimensional flows in homogeneous and isotropic aquifers in coastal regions.
