Notes:
A computer-assisted flow net analysis technique was developed and evaluated using a hypothetical heterogeneous aquifer with spatially variable recharge. Flow nets were derived and analyzed for cases with differing piezometric observation density and accuracy. Using a criterion to determine a best approximation to the observed piezometric surface, the transmissivity distributions implied by fitted surfaces were compared with the known true transmissivities. Where an optimum approximation to the piezometric surface was clearly defined, the resulting computed transmissivities compared favorably with the known values. With sparse or inaccurate observations, it became increasingly difficult to identify an optimum solution. The experiments illustrate some of the difficulties inherent in the ground-water inverse problem and the flow net analysis method. Application of the method to real field cases has yet to be tested.
