• 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 numberd, locations and combinations of groins, jetties, detached breakwaters, seawalls, and beach fills. Other features included 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 id presented, and simulations of hypothetical as well as prototype situation are given to demonstrate bthe capabilities of the system.
