Numerical simulation analysis of the interaction of lakes and ground water
Thomas C. Winter
1976, Professional Paper 1001
Because the interrelationship of lakes and ground water is perhaps the least understood aspect of lake hydrology, vertical-section, steadystate, numerical-model simulations were run to evaluate the factors that control the interaction of lakes and ground water. The study is concerned only with lakes encircled by water-table mounds that are at...

Documentation of finite-difference model for simulation of three-dimensional ground-water flow
Peter C. Trescott, S. P. Larson
1976, Open-File Report 76-591
User experience has indicated that the documentation of the model of three-dimensional ground-water flow (Trescott and Larson, 1975) should be expanded. This supplement is intended to fulfill that need. The original report emphasized the theory of the strongly implicit procedure, instructions for using the groundwater-flow model, and practical considerations for...
