Axisymmetric Modeling Using MODFLOW‐USG

Groundwater, 2019
Abstract Axisymmetric groundwater models are used for simulating radially symmetric conditions. Groundwater simulators built specifically to model axisymmetric conditions are most commonly used for simulating aquifer tests. Although some numerical models capable of simulating flow and solute transport that are developed in the ...

Modeling Multiaquifer Wells with MODFLOW

Groundwater, 2004
Multiaquifer wells, i.e., wells that are open across more than one aquifer, can have a profound effect on the hydraulics of a ground water system. These wells change the physical system by establishing direct hydraulic links between otherwise isolated strata.

SEEPAGE, a New MODFLOW DRAIN Package

Groundwater, 2004
Abstract The prediction of the location of ground water discharge areas is a key aspect for the protection and (re)development of ground water‐dependent wetlands. Ground water discharge areas can be simulated with MODFLOW using the DRAIN package by setting the drain level equal to the topography, while the conductance is mostly set to

A Parallel PCG Solver for MODFLOW

Groundwater, 2009
Abstract In order to simulate large‐scale ground water flow problems more efficiently with MODFLOW, the OpenMP programming paradigm was used to parallelize the preconditioned conjugate‐gradient (PCG) solver with in this study. Incremental parallelization, the significant advantage supported by OpenMP on a shared‐memory computer, made ...

MODFLOW data extractor program

Open-File Report, 2005
Abstract : EXTRACTOR is a program that extracts data from formatted and labeled MODFLOW head or drawdown files or from MODFLOW-GWT concentration or velocity files. The user specifies the number of rows, columns, and layers in the target data file, the desired time step or move number, and the range of rows, columns, and layers for which data should be ...

2011
This study examines the dynamic of underground water in the hydrogeological basin of korisos. This area is located in West Makedonia, at the prefecture of Kastoria. It is a sub-basin of the basin of kastoria s lake and is drained by the river Xiropotamos. The study area covers an area of 89.25km2 of which 24.6 belong to lowlands and 64.65km belong to
