Abstract : The Waterways Experiment Station's Implicit Flooding Model (WIFM) and the transport model WIFM-SAl were applied to investigate the hydrodynamic and mass transport in Lower Green Bay and Fox River, Wisconsin, before and after the proposed Confined Disposal Facility (CDF) expansion. Three hydrodynamic conditions (high, intermediate, and low flow) were simulated in WIFM with the existing CDF and the proposed expansion in place. The hydrodynamic results of these simulations were conducted in the Lower Green Bay area. The first group of simulations consisted of an instantaneous injection of tracer released at the mouth of the Fox River. The second group involved a continuous injection of tracer across the numerical grid boundaries. All simulations were conducted with and without the CDF expansion. From these results it was found that the flow exchange differences caused by the proposed CDF with Peats Lake Bay are insignificant, and the CDF expansion simply redistributes flow by increasing, by way of the main channel, to Middle Bay and by reducing discharge through the cross section between Grassy Island and the expanded CDF. The transport test for instantaneous dye injection, in the presence of the CDF expansion, showed an insignificant effect on the movement of material from the mouth of the Fox River through the Lower Green Bay area. For the continuous boundary injection patterns of concentration, contours were similar for both the existing and proposed conditions.
