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

Patterns and Age Distribution of Ground-Water Flow to Streams
TL;DR: In this paper, the authors used a particle tracker to determine flow paths in a stream subsystem, to establish the relation between ground-water seepage to points along a simulated stream and its source area of flow, and to determine groundwater residence time in stream subsystems.

TL;DR: This work solves a subset of community test problems from this application field using MODFLOW, a standard groundwater flow model, and IFFCO, an implicit filtering algorithm that was designed to solve problems similar to those of focus in this work.

TL;DR: The results from the present study suggest that the EPM approach is capable to reproduce the spreading of a TCE plume at intermediate scales with sufficient accuracy for groundwater resources management and the planning of contamination mitigation strategies.

Semi-analytical homogeneous anisotropic capture zone delineation
TL;DR: In this article, an algorithm for the quick delineation of capture zones using complex discharge potential is presented. But the method is limited to a homogeneous domain with anisotropic transmissivity.

TL;DR: In this paper, the authors used high-resolution lidar scans of a braided stream deposit to investigate solute transport characteristics and streamline-based connectivity that are lost when simulating the outcrop heterogeneity using geostatistical methods based on two-point covariance functions.
