Abstract

This paper evaluates the utility of mathematical models for prediction of the planform movement of beach nourishment projects. The results of one-line models (analytical and numerical) are compared to the evolution of nine laboratory-scale model beachfills. Several methods of planform modeling are evaluated, varying in complexity. Comparison of planform modeling suggests that, in some circumstances, using a simple analytical treatment of refraction may be a feasible alternative to using more rigorous numerical wave modeling for shoreline modeling purposes. The relative ability with which different equations for net longshore sediment transport rate reproduce observed beachfill evolution is discussed. Information on the effect of wave climate and beachfill geometry on beachfill lifetime is extracted from the laboratory study. The observed effect of lower wave height, greater beachfill length, and the tapering of a beachfill is a greater beachfill lifetime, in agreement with conventional wisdom. Increasing beach slope and decreasing wave period are both observed to cause a slight decrease in beachfill lifetime.
