Unformatted text preview: aquifers. An optimized continuation method for modelling flow in highly heterogeneous domains is introduced and implemented in a Graphical User Interface (GUI) environment. While the domain geometry is simple, the main computational challenge is to solve the seawater intrusion problem on large numerical grids, with both nonlinear and highly variable coefficients. The numerical results are then analysed in terms of spatial statistics, such as the standard deviation of the seawater interface elevation versus distance from the seashore (σZSALT(x)). 2 PROBLEM FORMULATION AND NUMERICAL MODEL Seawater intrusion is modeled in the framework of the sharp interface approach, while still retaining the essential feature of aquifer variability in the 2D plane. Our approach assumes that seawater and freshwater are immiscible fluids, and relies on pressure equilibrium relations (Ghyben-Herzberg) to close the resulting system of equations. In this 2D Modélisation stochastique de l'intrusion saline en 2D plan 72 framework, all variables and parameters are spatially distributed in (x,y). Applying the hydrostatic assumpt...
