Abstract:

This paper presents a parameter sensitivity study of a two dimensional flow and transport model of a contaminated site. Hydrogeological and site data from previous investigations were used for calibration. The U.S.G.S. contaminant transport model (MOC) was used. Ranges were identified to relate concentration error to parameter error. Porosity and anisotropy were found to be the most influential of the model parameters studied.
