Solute Transport Models

Solute transport models are essential tools for understanding and forecasting chemical concentrations in groundwater. Mixing in natural porous media is a slow process that can control the overall rate of chemical reactions; a lack of mixing causes chemical concentrations to be spatially variable. In this thesis, Peter Oates (Ph.D. 2007) developed and experimentally validated a new solute transport modeling framework that approximates the correct amount of chemical reaction and provides concentration probability density functions, which are needed to address laws and regulations based on maximum contaminant levels. The figure above is part of the numerical simulation of a hydrocarbon spill undergoing an oxygen-limited chemical reaction in a random field. The top image shows a concentration map of hydrocarbon. The bottom image shows oxygen.
