PHYSICAL MODELLING OF BEACH EROSION AND LITTORAL DRIFT

Otavio J. Sayao, Robert B. Nairn

Abstract


A new procedure for physical modelling of beach sedimentary processes is presented. It is shown that the modelling requirements proposed by Dean (1985) are necessary but not sufficient for dynamic similarity. Quantification of scale effects due to slope and relative grain size scaling conditions enables extrapolation of the physical model results to prototype situations. Selected examples of the application of the proposed model design are also given.
