TLDR
A computer program for simulating ground-water flow in three dimensions by using a block-centered finite-difference approach and has a modular structure, which permits the addition of new packages to the program without modifying existing packages.Abstract:
A computer program for simulating ground-water flow in three dimensions is presented. This report includes detailed explanations of physical and mathematical concepts on which the model is developed. Ground-water flow within the aquifer is simulated by using a block-centered finite-difference approach. The program is written in Fortran 77 and has a modular structure, which permits the addition of new packages to the program without modifying existing packages.read more

An efficient approach for successively perturbed groundwater models
P. Patrick Wang,Chunmiao Zheng +1 more
TL;DR: In this article, a new solution to a system of linear equations perturbed by the changes in aquifer properties and/or sinks/sources can be obtained as the sum of a nonperturbed base solution and the solution to the perturbed portion of the linear equations.

TL;DR: In this article, the authors describe the application of a parallel implementation of the implicit filtering algorithm to a control problem from hydrology, where they seek to control the temperature at a group of drinking water wells by placing barrier wells between the drinking water well and a well that injects heated water from an industrial site.
