Dispersion Analysis of Humboldt Bay, California, Interim Offshore Disposal Site
Abstract
The dispersive characteristics of an interim offshore dredged material disposal site located seaward of the entrance to Humboldt Bay, California, are investigated. These characteristics must be known to determine potential impact of the dredging operation on the local environment. Two phases of investigation were employed. A short-term analysis of the disposal operation was conducted to examine the immediate fate of material following release from the barge and subsequent descent to the ocean bottom. The second phase examined the long-term fate to determine whether local ocean currents are capable of eroding and transporting deposited material beyond the designated limits of the site. Results of this study indicate the site to be nondispersive, with little erosion and transport of material indicated under both normal and moderate storm conditions. Disposal site classification, Sediment fate, Disposal site stability, Sediment transport, Dredged material.
