BEACH IMPROVEMENT SCHEMES IN FALSE BAY

D.H. Swart, J.S. Schoonees

Abstract


A physical sediment model was used to design two beach improvement schemes in False Bay near Cape Town. Different layouts of T, L and detached breakwaters were tested to determine their effect on the beach and how they improved bathing conditions. Although caution was exercised to eliminate scale effects, it was found to be necessary to minimize their influences. A method was devised to do so which proved successful. It was found that equilibrium shoreline positions were reached after 4 years (prototype time). Sand feeding after construction will be necessary to minimize the deleterious effects of the breakwaters on the adjacent beaches.
