Book Description
Four separate and distinct major problems exist at Mission Bay proper at the present time, with an additional beach erosion and bluff collapse condition occurring at Sunset Cliffs. The major problems at the Bay include: (a) a dangerous condition at the jettied entrance produced by frequent breaking waves, (b) short period waves of excessive height attacking moored boat areas in Quivira Basin, (c) long period seiche or surge in Quivira Basin and other locations within Mission Bay, and (d) a complete closure of the exit of the San Diego River Floodway by littoral material being trapped between the middle and south jetties. In order to provide long-term (permanent) solutions to the four principal problems which exist at Mission Bay, knowledge of the amount of littoral material which is moving past the entrance channel to the Bay is required, along with an understanding of the monthly occurrence of this flow of material by direction. This information will be used to evaluate the potential effects of littoral transport, beach scour, and deposition on the functional design of proposed structural improvements.
