Abstract: A surface-water flow and contaminant transport model was developed and combined with an existing ground-water flow and transport model (FTWORK) to study the impact of contaminated ground water on the water quality of streams. Interacti on between ground-water and surface-water systems was represented by a stream-bed leakage term. Transport of the dissolved contaminants in the stream network is modeled by solving the one-dimensional advection-dispersion equation. Sorption and decay processes are consider during ground-water transport, while volatilization, sorption, settling and decay are considered during surface-water transport. Due to differences in the flow velocity, different time scales were used to model transport of contaminants in ground water and surface water.
