Los Angeles and Long Beach Harbors Model Enhancement Program: Three-Dimensional Numerical Model Testing of Tidal Circulation
Abstract
To meet future needs, the Ports of Los Angeles and Long Beach have undertaken a long-range cooperative planning effort known as the 2020 Plan. Under this master plan, a number of phased plans have been determined to accommodate future needs. These plans involve deepening of ship channels and harbors and creation of new landfills. The purpose of the study described in this report was to determine three-dimensional hydrodynamics of tidal and wind- driven circulation for existing conditions as well as a plan condition selected by the ports. This goal was accomplished by applying a state-of-the-art, 3-D numerical hydrodynamic model called GH3D. The model results also were used to drive a separate water quality model. In order to calibrate and verify the GH3D model, comprehensive field data were collected in the summer of 1987. These included surface elevation data measured at eight locations, current measurements with in situ current meters deployed at nine stations, current velocity profile measurements taken at major entrances to the harbors and interior channels, and a drogue study. The purpose of the study described in this report is to determine three-dimensional hydrodynamics of tidal and wind- driven circulation for the existing harbors and to demonstrate model use in investigating a Phase 1 configuration of a plan determined by the OFI study and selected by the ports.
