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

Integrated modelling for groundwater contamination from polluted streams using new protection process techniques.
TL;DR: In this article, a coupled model of MODFLOW and MT3DMS (Mass Transport 3-Dimension Multi-Species) was developed to integrate two water supply systems, surface water (polluted drains and canals) and ground water, to identify the contamination process of the groundwater from drains as fresh water is polluted and the contamination level exceeds the standard limits.

Numerical investigation of the spatial scale and time dependency of tile drainage contribution to stream flow
TL;DR: In this paper, a physically based coupled hydrologic model was applied to a 45 km 2 agricultural Iowa watershed, where tile drainage was incorporated through an equivalent porous medium approach, calibrated though numerical experimentation.

Upscaling hydraulic conductivity : theory and examples from geohydrological studies
TL;DR: In this article, the authors present an overview of the theory of upscaling hydraulic conductivity and describe two case studies in which some of this theory has been applied, in a deterministic and in a stochastic setting.

Integrated modeling as a decision-aiding tool for groundwater management in a Mediterranean agricultural watershed
TL;DR: In this paper, a decision-aiding methodology for agricultural groundwater management is presented; it is based on the combination of a watershed model, a groundwater flow model, and an optimization model.
