Abstract : The existing, comprehensive fixed-bed model of the Grays Harbor estuary was used to determine the effects of several plans for rehabilitation of the north jetty. Model tests were conducted to determine the effects on hydraulic, salinity, shoaling, and dye dispersion characteristics. Test results consist of current velocity, tidal height, and salinity measurements; shoaling patterns in the entrance area; dye dispersion characteristics; and photographs of surface current patterns. Model test results indicated that a 650-ft extension to the north jetty would cause only insignificant local changes in current velocities and patterns in the entrance area. (Author)
