Available in PDF, EPUB and Kindle. Book excerpt: A 1-to-50 scale physical model of Half Moon Bay, Grays Harbor, WA, was constructed at the U.S. Army Engineer Research and Development Center's Coastal and Hydraulics Laboratory in Vicksburg, MS. The purpose of the physical model was to support studies being conducted by the U.S. Army Engineer District, Seattle. Specifically, the model results will be used to assess the potential long-term response of the Half Moon Bay shoreline to expected storm waves and surge levels, provided the breach fill between South Beach and the bay remains intact. The physical model eroded the June 2003 shoreline until a near equilibrium was achieved in the model with the dune recession line closely matching the existing vegetation line. This result indicated Half Moon Bay is approaching an equilibrium shoreline planform shape as it adjusts from an influx of sediment resulting from the 1993 breach. However, scale effects in the physical model related to sand transport mean that the dune recession reached in the model for a constant water level and wave energy is less than what would occur in Half Moon Bay under the same constant conditions. Therefore, some additional erosion of the dune should be expected in the coming years. The physical model did not include the benefits of placing dredged material in Half Moon Bay. The model demonstrated the gravel/cobble transition material is mobile with substantial erosion and transport of the gravel from the area of original placement toward the eastern portion of the bay.

Available in PDF, EPUB and Kindle. Book excerpt: Large changes in the distribution of sediment near the entrance to Grays Harbor, Washington, have occurred since the long rock jetties were built to confine flow. Spits to the north and south of the entrance have grown, the entrance channel has deepened, and the outer bar has eroded and moved offshore. The shorelines of North Beach and South Beach have experienced significant amounts of both erosion and accretion since the jetties were constructed around the turn of the century. Recently, the erosion rate at South Beach has increased and, because Half Moon Bay is growing at the expense of the shoreward side of Point Chehalis, the vegetated portion of the spit is now less than 350 ft wide at the narrowest section. The US Army Corps of Engineers, Seattle District, requested that Battelle/Marine Sciences Laboratory evaluate long-term trends in erosion near the entrance to Grays Harbor.
