Abstract

Groundwater contamination is frequently concentrated in the surflcial or water-table aquifer. The first remediative step of aquifer clean-up consists of the extraction of the polluted water by pumping. Depending on the pumping rates, this may lead in situations where the surficial aquifer is shallow to significant drawdowns of the water-table. Modeling the horizontal solute transport in such a pumped unconfined aquifer by means of a classical 2D transport model that assumes a constant aquifer thickness, may lead to significant errors and, consequently, bias in the remediation strategy. Thus there is a desire to have an improved 2D solute transport model for simulating remediation in a phrea
