A waste load allocation modeling study was conducted in South San Francisco Bay, California. Relatively numerous reports on hydrodynamics and less complete data for water quality, especially sediment levels, in the Bay were reviewed for use in the study. Simulations were based on the premise that sediments maintain equilibrium over long periods of time. Copper concentrations were simulated using different loading conditions describing different scenarios. Nontidal transport results were obtained for suspended solids, copper, nickel, and lead. The wide ranges of historical water quality data were addressed through sensitivity analysis of unsteady nonpoint source loads. For demonstration purposes, the domain for tidal simulations covered only the regions south of Dumbarton Bridge. The effects of the reduction of point-source loads over the past few years and of the droughts that began in 1987 were simulated using appropriate loading conditions.
