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

TL;DR: Budget calculations have been changed to double precision, which improves the accuracy of budget calculations, and new options have been added such as the ability to save calculated heads in formatted files and save budget data in more compact unformatted files.

Artificial recharge of groundwater: hydrogeology and engineering
TL;DR: In this article, the authors proposed a system for artificial recharge of groundwater, which is achieved by putting surface water in basins, furrows, ditches, or other facilities where it infiltrates into the soil and moves downward to recharge aquifers.

TL;DR: While the process is essentially ubiquitous in coastal areas, the assessment of its magnitude at any one location is subject to enough variability that measurements should be made by a variety of techniques and over large enough spatial and temporal scales to capture the majority of these changing conditions.

Semianalytical Computation of Path Lines for Finite‐Difference Models
TL;DR: In this paper, a semianalytical particle tracking method was developed for use with velocities generated from block centered finite-difference ground-water flow models, based on the assumption that each directional velocity component varies linearly within a grid cell in its own coordinate directions.
