OVERVIEW OF THE DESIGN PROBLEM
CHARACTERIZATION OF THE SITE
The site to be considered is a sheltered location within an estuary. The shoreline is a low bluff about 9
feet high. At mean low water (MLW), it is fronted by a 15 ft. wide beach. The Stillwater level is at the toe of the
bluff at mean high water (MHW). The bluff slope is approximately 1:1, and the soil is fine-grained, mostly sand
and silt, with a heavy overgrowth of brush and other plants. The number of trees standing in the water and lying
on the beach is evidence of a long-term and chronic erosion problem. The beach itself consists of fine to coarse
grained material, mostly sand, but with s significant fraction of gravel and cobbles. The offshore bottom slope is
approximately 1 on 33.
WATER LEVELS
The spring tide range and the mean tide level were determined by reference to Tide Tables [US
Department of Commerce (1976)]. Local experience indicated that 2 feet of storm setup was appropriate. The
site profile and water levels are summarized on Figure 91.
