INTERACTIONS OF THE BEACH-OCEAN-ATMOSPHERE SYSTEM AT VIRGINIA BEACH, VIRGINIA.
Abstract
A number of interactions among beach variables are investigated by sequential linear multiregression analysis as programmed for high-speed computers. Study includes influence of beach geometry, wave characteristics, tidal effects, and local wind conditions on velocity of longshore currents, deposition and erosion on the lower foreshore, and response of grain size and beach slope to shore processes. Most-influential combinations of variables arbitrarily designated as 'process' variables are in general agreement with significant variables of wavetank experimentation, and substantiate intuitive judgments regarding relative importance of these variables on natural beaches. Results suggest that certain additional variables, seldom examined under controlled conditions, be studied in combination with variables normally examined in wave tanks. Time lag between inception of a group of 'processes' and moment of their maximum effect on the 'response' is also investigated. (Author)
