Watershed and Pollutant Loading Studies Services

ERD has been at the forefront of watershed and pollutant loading studies for more than 20 years. During the early 1990s, ERD developed some of the initial spreadsheet-based pollutant loading models to estimate nonpoint source loadings from watersheds. ERD also has developed and maintained a database of event mean concentrations for runoff generated in a variety of land use categories throughout the State of Florida. During the late 1990s, ERD pioneered the use of a GIS-linked spreadsheet model for estimation of runoff volumes which combines land use categories with soil types to generate estimates of annual runoff volumes.
