Abstract:

A series of boat waves were directed across the tidal flat at varying water depths to 1 compare the different amounts of wave energy expended in each area of the tidal flat and 2 examine the post-boat wave effects on sediment resuspension and deposition. In general, the outer portion near low tide mark of the tidal flat receives between one third and one half more wave energy than the shallow region. There is a great deal of energy lost through bottom friction as the wave form passes through shallow water. Because of this energy gradient, the outer portion of the tidal flat appears to be the most dynamic with alternate periods of resuspension and deposition. In contrast, the inner area is primarily depositional.
