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.

A Coupled Land-Atmosphere Simulation Program (CLASP): Calibration and validation

William J. Gutowski, +6 more
- 27 Aug 2002 - 
TL;DR: In this article, the authors present a model and application designed to study the coupled land-atmosphere hydrologic cycle, following water from its inflow into a region by horizontal atmospheric transport through surface atmosphere exchange processes and aquifer recharge to outflow as runoff and river discharge.

Development of the Community Water Model (CWatM v1.04) – a high-resolution hydrological model for global and regional assessment of integrated water resources management

Peter Burek, +12 more
- 21 Jul 2020 - 
TL;DR: The novelty of CWatM is its combination of state-of-the-art hydrological modeling, modular programming, an online user manual and automatic source code documentation, global and regional assessments at different spatial resolutions, and a potential community to add to, change, and expand the open-source project.

Modeling the subglacial hydrology of the late Pleistocene Lake Michigan Lobe, Laurentide Ice Sheet

Christopher W. Breemer, +2 more

Focused groundwater discharge of phosphorus to a eutrophic seepage lake (Lake Væng, Denmark): implications for lake ecological state and restoration

Jacob Kidmose, +9 more
- 17 Sep 2013 - 
TL;DR: In this paper, a study on Lake Vaeng in Denmark demonstrates a high potential for loading of phosphorous via groundwater to seepage lakes, and the average total phosphorus concentration in discharging groundwater sampled just beneath the lakebed was 0.162mg TP/l and thereby well over freshwater ecological thresholds.

Integrated embedding optimization applied to Salt Lake Valley aquifers

Ali Gharbi, +1 more
- 01 Mar 1994 - 
TL;DR: In this paper, the authors adapted the embedding optimization modeling approach to aid sustainable groundwater quantity and quality management of complex nonlinear multilayer aquifers Implicit block-centered finite difference approximations of the quasi-three-dimensional unsteady flow equation and Galerkin finite element approximation of the two-dimensional advection-dispersion transport equation are embedded directly as constraints in the model.
