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

A simulation and prediction of agricultural irrigation on groundwater in well irrigation area of the piedmont of Mt. Taihang, North China
TL;DR: In this paper, the effect of future irrigation patterns on the decline of the groundwater table is examined with the aid of MODFLOW, which is calibrated for five observation wells in the county and fitted the observed data well over a 7-year period.

A Three-Dimensional Mixing Cell Solute Transport Model and Its Application
TL;DR: In this paper, a three-dimensional mixing cell solute transport model was developed based on the principles of conservation of mass for water and solute, which is used to predict chloride concentration changes resulting from proposed future pumping to supply municipal water for the city of El Paso, Texas.

Modeling nitrate from land-surface to wells' perforations under agricultural land: success, failure, and future scenarios in a Mediterranean case study
TL;DR: In this paper, the authors used deep soil sampling to calibrate vertical flow and nitrogen-transport numerical models of the unsaturated zone under different agricultural land uses to assess whether this spatial variability can be characterized on the basis of land use and standard agricultural practices.
