Los Angeles and Long Beach Harbors Model Study. Numerical Analysis of Tidal Circulation for the 2020 Master Plan.

Abstract

A study to determine the effect of the proposed 2020 Master Plan on tidal circulation in Los Angeles and Long Beach Harbors was conducted using a numerical model with a two-dimensional depth-averaged formulation of the hydrodynamic equations. The model, which had been verified in a previous study, used an implicit finite-difference scheme to numerically solve the equations. To observe the dispersion of conservative substances, the model also incorporated the two-dimensional conservative constituent transport equations. The 2020 Master Plan consists of placing 2600 acres of landfill at various locations throughout the harbors. Tidal circulation was studied for 70-hr sequences of spring, mean, and neap tides for each of three harbor configurations: (1) existing configuration (1983), (2) landfills placed on existing bathymetry, and (3) landfills placed with increased channel depths. The 2020 Master Plan produced no changes in tidal elevation or phase throughout the harbors.
