Flow and salt transport in the Suwannee River estuary, Florida, 1999–2000: Analysis of data and three-dimensional simulations

A three-dimensional numerical model was developed to assist in the evaluation of the effects of changes in freshwater flow on the salinity regime of the lower Suwannee River, its estuary, and Suwannee Sound. Hydrodynamic and salt-transport
modeling were supported by data from a comprehensive data-collection network operated in the lower Suwannee River during 1998-2000. The study area included all of the downstream-most 12 kilometers of the Suwannee River, Suwannee Sound, and part of the Gulf of Mexico. Development, calibration, and application of the hydrodynamic and salt-transport model were completed by using data primarily collected during October 1999-September 2000.
