Abstract:

A three-dimensional (3D) numerical hydrodynamic and water quality model (WQM) of the Chesapeake Bay and its major tributaries has been developed by the US Army Engineer Waterways Experiment Station (WES) to model water quality throughout the bay. Analysis and interpretation of model behavior was an enormous task due to both the volume and complexity of the numerical results produced by the model. A variety of traditional and modern graphical analysis techniques were used to display model behavior. The benefits derived from and problems encountered in applying these techniques are discussed. Computer generated video animations of time-varying salinity fields and water quality variables in the bay have been produced to demonstrate the application of scientific visualization techniques to the analysis of model behavior.
