Numerical Modeling System for Shoreline Change.

Abstract

This report describes a combined system of numerical models called GENESIS, developed for calculating shoreline change as caused primarily by wave action. The system is based on the one-line theory, for which it is assumed that the beach profile remains unchanged, thereby allowing beach change to be described uniquely in terms of the shoreline position. As opposed to previous models based on the same concept, GENESIS is generalized in the sense that a simple user interface allows the system to be applied to a diverse variety of situations involving almost arbitrary numbers, locations, and combinations of groins jetties, detached breakwaters, seawells, and beach fills. Other features include in the system are wave shoaling, refraction, and diffraction; sand passing through and around groins, and sources and sinks of sand. An overview of the modeling system is presented, and simulations of hypothetical as well as proto-type situations are given to demonstrate the capabilities of the system.
