Pacific Groundwater Group has extensive experience using computerized, numerical models to simulate groundwater flow and contaminant transport under many different conditions. The numerical models we commonly use include MODFLOW and PATH3D. In addition, we are also proficient with many state-of-the-art pre- and post-processing modeling packages, such as Groundwater Vistas, Visual MODFLOW, ModelCad, and PEST.
These models allow us to simulate how pumping from one or more wells will affect an aquifer system. This information is often crucial for developing optimal strategies for groundwater management. It also allows us to quantify the interactions between groundwater and surface water—an increasingly important issue in the Northwest, where obtaining a water right often depends on impacts to stream flows. Numerical models also allow us to predict where—and how fast—contaminants will move under various pumping scenarios.
We also use many analytical flow models, including RESSQC, GPTRAC, MWCAP, QuickFlow, and TwoDAN, which are useful for delienating capture zones and tracking particles.
