Using Flux Information at Surface Water Boundaries to Improve a Groundwater Flow and Transport Model

Abstract

We investigated the performance of a groundwater flow and solute transport model when different combinations of hydraulic head, seepage flux, and chloride concentration data were used in calibration of the model. Using additional calibration data, beyond traditionally-used head data, improved performance of the model during a test period separate from the calibration period. This confirms the merit of collecting seepage flux and concentration data, and using them together with head data in parameter estimation for a numerical groundwater model. Our work also contributed to improvement of the Army Groundwater Modeling System (GMS), by identifying numerous software problems and working with GMS developers to correct them.
