Toward a 3-Dimensional Numerical Modeling of Tidal Currents in San Francisco Bay

摘要

A deterministic 3D model for simulating hydrodynamics and salinity, based on the code Si3D, was implemented for San Francisco Bay. Several scenarios were modeled involving different months with varying estuarine conditions between October 2007 and June 2008. Bay bathymetry, coastal and river water levels, and salinity were used as input. This paper presents preliminary results of the modeling project. The paper discusses results obtained with two meshes and addresses the effects of boundary conditions on the numerical results. Predictions of tidal current patterns were developed for a study of water quality and quantitative pathogen monitoring in the sub-embayment of San Pablo Bay.
