Abstract:

The Lake Okeechobee watershed phosphorus model was developed to route flows and phosphorus loadings associated with point and nonpoint sources through a watershed transport system, and account for phosphorus assimilation within the transport system. The model includes water quality algorithms that account for phosphorus assimilation in wetland areas, which are typically located in the overbanks adjacent to stream channels, and hydraulic algorithms that account for the distribution of flow and phosphorus loadings between the stream and wetland areas. The modified model was tested on several pilot basins in the study area to determine the model's capability of accurately simulating seasonal and annual loadings.
