SWIL: A Custom GIS-Based Pollutant Load Model for the Indian River Lagoon

Florida’s Department of Environmental Protection has identified the Indian River Lagoon and Banana River Lagoon as nutrient impaired and has issued TMDLs for nitrogen and phosphorus. The TMDLs were established based on estimated relationships between nutrient loading and seagrass depth limits. After the TMDLs were established, data were updated, enabling a new look at the TMDL models and seagrass coverages, and questions arose regarding pollutant loading and seagrass relationships. A custom GIS model called Spatial Watershed Iterative Loading, or SWIL, is being used to create a spatially varied, continuous monthly simulation of runoff for the drainage basin that provides a more accurate representation.
