Abstract

A finite element based integration method is developed to identify the spatial distribution of parameters that characterize contaminant transport in two dimensional irrotational potential flow in the regions over which a concentration front has passed. This integration method can avoid the difficulties often occuring in direct solution. An example shows that this method performs well in both noise free and relatively high noise level environments. The equations are derived for cases in which the dispersivity varies with position. The method has not been tested for spatially varying dispersivities in the two-dimensional case
