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

Numerical Simulation of Groundwater Flow in a River Valley Basin in Jilin Urban Area, China
TL;DR: In this paper, a groundwater numerical flow model was established by using the groundwater modeling system based on data from 190 boreholes, which was calibrated by trial and error, simulated results were compared to the observed head and contour maps, which were generally in good agreement, and the root mean squared error was 0.66 m. Sensitivity analysis was carried out and recharge proved to be the most sensitive factor in this model.

Which Groundwater Remediation Objective is Better: A Realistic One or a Simple One?
Xiaolin Ren,Barbara S. Minsker +1 more
TL;DR: In this article, the authors examined the benefits of developing a realistic cost function using two multiobjective groundwater remediation case studies and found that realistic cost functions find better solutions than the simplified cost functions, as well as identifying more optimal solutions on the Pareto frontier than the other functions.
