Application and Validation of Three-Dimensional Model in a Shallow Lake
Publication: Journal of Waterway, Port, Coastal, and Ocean Engineering

Abstract
This paper describes the validation and application of a hydrodynamic and sediment transport submodel of the Lake Okeechobee environment model (LOEM). This model simulates the sediment resuspension and transport due to wind driven current and waves. The LOEM simulated conditions in Lake Okeechobee from October 1, 1999 to September 30, 2000. The model reasonably simulated water depth, water temperature, current velocity, and suspended sediment concentrations in the validation period. To model sediment resuspension, the processes of wind generated waves and the resulting stresses on the lake bed were simulated. The LOEM is used to predict the impact of sediment processes in the lake under different management scenarios and environmental conditions (high/low lake stages and storm events/hurricanes). This model also is used to estimate light extinction coefficient. Results from the LOEM allow managers to predict how phosphorus-rich mud sediments move in the lake between the marsh and open water areas, and under what conditions they are most likely to be resuspended and transported.
