The hydrologic-hydraulic behavior of wetlands and transitional upland-wetland areas on coastal flat terrains in the Cocohatchee Canal Watershed in Collier County, Florida was simulated by using a two-dimensional sheetfiow routing model. The model performs dynamic routing of overland runoff through natural wetland areas while incorporating anthropogenic features such as canals, dikes, and water control structures. The calibrated watershed model was used to assess runoff under existing and future development conditions with watershed management alternatives. The resulting runoff was linked to an open channel flow routing model, and used to evaluate various wetland restoration measures.
