Abstract

A general purpose numerical groundwater model based on the boundary element method was developed and applied to various groundwater flow cases to test its validity. The model is micro-computer based and capable of dealing with two dimensional, steady-state problems. Nonhomogeneous domains are dealt with by defining multiple zones, with each zone being homogeneous but not necessarily of the same conductive properties as adjacent zones. Wells may be included anywhere in the problem domain, and may be either specified flow or specified potential. Cutoff walls are also accommodated by the model. Unknown potential or flux values are calculated on the boundary points and at interior points which may be specified by the user;The model was written in modular form to allow for modification. Considerable effort was placed into automating many of the routine tasks involved in describing a problem, making the input of the model as simple as possible, particularly for those unfamiliar with the boundary element method. Emphasis was also placed on demonstrating the computational aspects of applying the boundary element theory.
