Abstract

This resource constitutes the groundwater and saltwater intrusion portion of the modeling chain developed under SERDP Project RC-1701.

Several models and modeling systems were used to develop the model. The associated files are also a part of this resource.

1. Groundwater Modeling System (GMS) version 8.2 - A pre- and post-processing tool to develop and evaluate the AdH-WASH module simulation results.

2. Computational Model Builder (CMB) version 2.0 - A pre- and post-processing tool to develop and evaluate the AdH-WASH module simulation results.

3. Adaptive Hydraulics (AdH) - WASH123D - AdH was the preferred computational framework for hydraulic modeling in development by the U.S. Army Engineer Research and Development Center (ERDC). AdH included density-dependent flow and transport equations. However, for this study the external WASH module formulation was used. This module’s capabilities were being incorporated into AdH and its results were based on the WASH123D model’s capabilities. WASH123D was a physically-based finite element numerical model that could compute coupled density-dependent flow and solute transport in the groundwater system. The 3D subsurface density-dependent flow and solute transport equations were solved using the AdH-WASH model for this study. The Galerkin finite element method was used to solve the flow equation, while the Lagragian-Eulerian finite element method was used to solve the transport equation.

The WASH123D Graphic User Interface (GUI) was utilized to generate input files for flow simulation. For the transport simulations, the FEMWATER GUI was used to generate the transport input file that was subsequently translated to the AdH-WASH format.

A full list of details can be found in the final report for the SERDP project.
