The existing, comprehensive fixed-bed model of the Grays Harbor estuary was used to determine the effectiveness of three proposed dredged material areas in the estuary entrance in retaining material deposited from a hopper dredge the effects of three proposed Sand Island Shoal Channel realignment plans including one plan with a confined disposal area on channel shoaling, current velocities, and salinities the effects of eight proposed confined dredged material disposal islands on channel shoaling and the effects of six channel improvement plans training dike, groin fields, and turningsettling basin on channel shoaling, current velocities, surface directions, salinities, and dye dispersion. Prior to conducting channel shoaling tests, a comprehensive shoaling verification of the navigation channel was completed.
