AND

Detailed daily topographic maps of beach and inner nearshore areas indicate a cyclic pattern to processes and responses in this non-tidal environment. This pattern is the result of complex interaction between changes in shoreline configuration, discontinuous nearshore sand bars, and environmental variables uch as barometric pressure, wind velocity, breaker height, and longshore currents. Of the 18 variables measured, barometric pressure appears to provide the best index for changes in coastal processes. The results of these variations are morphologic hanges in the beach and inner nearshore area. As a low pressure system approaches the coast here is an increase in wind velocity, breaker height and long-shore current velocity as barometric pressure drops. When the low pressure system passes barometric pres-sure rises and there is a reversal of wind direction with an accompanying reversal of longshore current direction. This cycle in conditions i accompanied by a pattern of responses in the position and morphology of the shore-line and sand bars. During high pressure and low energy conditions shallow discontinuous sand bars have some-what regularly spaced rip channels. The shoreline is slightly sinuous with protuberances behind the sand bars. Longshore currents are slow and small waves break on the bars causing their shoreward migration. Shoreline sinuousity increases as protuberances grow and emhayments are slightly eroded.
