Description
We created a ten layer model to simulate the flow and transport of chloride in Will County’s shallow aquifer with Groundwater Vistas software. This model is transient with yearly stress periods starting in 1950 and ending in 2020.
The groundwater flow model was developed using the U.S. Geological Survey (USGS) finite difference code MODFLOW-NWT (McDonald and Harbaugh 1988; Niswonger et al., 2011) within the graphical user interface Groundwater Vistas 7.24 (Rumbaugh and Rumbaugh, 2020). We simulated chloride transport with the MODFLOW post-processing package MT3D-USGS (Bedekar et al., 2016).
