Description:
The study summarized in this report is directed toward gaining additional knowledge on the unsteady performance of multilayer aquifers in response to heavy withdrawal of water from several wells distributed in the system. A recent status report on ground water problems in South Eastern United States clearly indicates that more detailed information is needed on this problem in order to describe appropriate management options for such multilayer aquifer regions. In the first phase of this modeling effort which was published in 1985, steady state ground water flow equations were studied and a steady ground water flow model was developed for multilayer aquifers. The second phase of the study, reported here, extends the steady state model to an unsteady multilayer ground water flow model which prepares the stage for contaminant transport model in multilayer aquifers which is the last phase of these model development efforts.
In the present study a regional two-dimensional flow analysis is formulated using finite element techniques for multilayer aquifers. Numerical solutions are presented to test the accuracy and efficiency of the proposed technique.
