摘要

A 3D hydrodynamic model has been successfully applied to Little Manatee River to characterize the mixing and transport process and residence time. The model employs horizontal curvilinear orthogonal grids to represent the complex river system that consists of branches and bayous. The model has been satisfactorily calibrated and verified by using two continuous data sets. The data sets consist of hourly observations of all forcing boundaries, including freshwater inputs,tides, winds, salinity and temperatures at bay boundary, and air temperatures, for model simulations. The calibrated and verified hydrodynamic model was used to investigate residence time in the Little Manatee River. Model simulations were conducted for 17 flow scenarios. Empirical regression equations have been satisfactorily derived to correlate ERT to freshwater inflow. Correlation coefficients R2 are 0.976 for ERT.
