Abstract: Two existing water quality mathematical models, STORM for stormwater runoff and RECEIV for receiving waters, have been adapted and applied to Broward County in Southeast Florida. The modeling used land-use data, results of previous local stormwater quality studies and other local studies conducted by the U. S. Geological Survey, and results of a water quality sampling program. The RECEIV unsteady state model for the canal system was adapted to handle outflow through an underflow gate and reversals in flow direction. Calibration of the models is considered satisfactory, but additional information on pumpage and scouring/deposition of sediments would be helpful. First-order chemical reactions are not very important in wet weather conditions due to short residence times. Pollutant runoff rates by land use obtained by modeling were used to identify priority areas for future land-use planning.
