Evaluation of Resuspension from Propeller Wash in DoD Harbors

Abstract

A study was conducted to evaluate impacts of resuspension from propeller wash in DoD harbors. This study included both field data measurement and calibration of numerical models. The study included three linked, yet separate studies, including resuspension potential by tug wash, fate and transport, and re-migration, re-deposition and re-contamination potential of the sediment plumes from tug wash. Model-data comparisons were conducted for both the erosion potential model (Graphic Maynord's model) and the fate and transport model (CH3D) for San Diego Bay, CA. The calibrated models were then used to evaluate propeller wash impact in Pearl Harbor, HI, and Sinclair Inlet, WA. Study results demonstrated that, in spite of the complexities associated with the transport and dynamics of propeller-wash induced sediment resuspension, study tools, including both key field data and adequately calibrated models, were effectively developed and applied to describe and predict key processes and impacts associated with propeller wash in DoD harbors.
