Steady salt water intrusion into coastal confined aquifer with inclined outflow face

Abstract

The interface that exists between fresh and salt waters in a confined coastal aquifer with an indined outflowface is analysed. The outflow face behaves in a way analogous to that of a surface of seepage. The a priori unknown interface is modified through an iterative process which uses constrained least square fit. The method of finite differences is employed for the solution. The influence of changes in the driving bead and inclination often  outnow face on the interface configuration and the quantity of free water flow are studied.
