Comparison of Numerical and Hydraulic Oceanographic Prediction Models.

Abstract

The Hydro-Numerical Prediction Model developed by Hansen is applied to San Diego Bay, and the results compared both with the hydraulic model and the real data obtained by field measurements. This allows one of the few good comparisons between numerical and hydraulic models for the prediction of actual conditions. The bay was divided into two sections that were run separately in order to obtain the desirable spatial resolution. This division required solving the problems of proper tuning and matching techniques between both portions. The solution involved the addition of an appended pseudo-bay to the first section of the model in order to compensate for the correct tidal prism. The effects of a proposed second open entrance in the southern part of the bay were studied. This bay but caused the currents in the center of the bay to be small which decreased dispersion in the central portion of the bay. In general, both models produced similar and reliable results, but there was a considerable reduction of cost and time with the numerical model. (Author)
