A numerical simulation of a site at the Savannah River Site is presented to demonstrate the GMS/FEMWATER capabilities. Tritium was selected as the chemical of concern for the transport simulation. Effects of the hydrogeologic parameters such as infiltration and pumping on the flow and tritium transport were investigated. The highly irregular geometry of the site resulted in a slow numerical convergence of the flow simulations. The initial conditions of the flow and mass of the tritium were crucial to this demonstration. The future modeling of the site should include a detailed mesh system, sufficient hydrogeologic and chemical data, and incorporation of a parameter estimation technique.
