BEM solution of stochastic seawater intrusion problems
In this paper, the stochastic saltwaterfreshwater interface location in coastal aquifer is sought, subject to the uncertainty of input parameters such as hydraulic conductivity, freshwater outflow, and pumping rate. The boundary element method, combined with an optimization technique, is used as the tool for deterministic solution to search for the interface location. A second order perturbation technique is employed to find the statistical moments of the prediction. Three saltwater intrusion examples of different geometries are examined.
