Three-dimensional hydrodynamic model set-up: a case study of middle Tennessee River

The Environmental Protection Agency's (EPA) Environmental Fluid Dynamics Code (EFDC) is a widely used hydrodynamics model that is no longer up to date with modern technology. As part of this research, an automated MATLAB based structured grid generator for EFDC was developed and was tested by developing a test model for Tennessee River near Chattanooga area. The test model was developed for a 9.92 km long segment of the Tennessee River starting from the downstream of the Chickamauga dam to upstream of Moccasin island. The model was calibrated against measured water flows, velocities and gage heights from January 1 to June 27, 2008. The Nash-Sutcliffe coefficients for velocities and gage heights were 0.788 and -6.61 respectively. Overall the model could simulate the field condition effectively. However, a detailed bathymetry is required, and the current limitation of the grid generators manual adjustments need to be addressed to produce better simulation results.
