Abstract
San Francisco Bay is roughly 60 miles long and 3-12 miles wide. The bay covers an area of approximately 400 square miles. The primary aim could be to characterize the salinity variation along the length of the San Francisco Bay, Investigate the role of surface water elevation and hydrodynamic processes in shaping the salinity gradient of the San Francisco Bay by analyzing tidal data, water velocity, and flow patterns. Two-dimensional averaged depth was used to build the San Francisco Bay water quality model. With measured field data collected between December 1, 2000, and December 2, 2000, this generated model was calibrated. The lake's four water quality metrics were selected to display the study's findings. Water levels, water temperature, salinity, and wind are these variables. The model has been checked and calibrated using data from a few chosen stations in San Francisco Bay. After then, over the period of December 1 to December 2, 2000, the model was calibrated. Calculations were made to determine the absolute mean error AME, normalized objective function NOF, and root mean square error RMSE of water depths. The lowest permissible error rate was reached when using the Manning number with a value of 40 m^(1⁄3)/s where the value for stations number 13,19,21 of RMSE respectively equal (0.85, 0.92, 0.86), NOF respectively equal (0.09,0.09,0.09), and AME respectively equal (0.74, 0.69, 0.75) . After that, a verification was done for the period December 16, 2015 to December 17, 2015 using data related to the water level and salinity.
