Equilibrium Beach Profile Scale-Model Relationship

Abstract

A model law for two-dimensional, laboratory beach profiles assumed to be at equilibrium is considered herein. An experimental program has been performed and the extensive laboratory beach profile data indicate a relationship or model law between the four basic scale ratios; the horizontal scale, vertical scale, sediment size ratio, and the relative specific weight ratio. Graphical forms of the experimentally derived model law are presented for efficient use. Recommendations are presented to optimize the practical application of scale model technology to coastal movable beds.
