Abstract

This paper is a continuation of the paper with the same name, presented on the Xlth Conference on Coastal Engineering by the first author [1] , in which a mathematical theory was given about the behaviour of a coast after the construction of a groyne system. Now this paper extends the former paper theoretically and practically. 1. Theoretically a computer program has been made in which the influence of diffraction behind the groyne has been taken into account. 2. Practically the coastal constants used in the theoretical model of the coast will be expressed in terms of wave height and wave direction, based on the theory of SVASEK [2] . Results are given of computations with a coastal model in which the coast is schematized to one line (one-line theory) and a model in which the coast is schematized to a beach line and on mshorelme (two-line theory). The influence of changing wave conditions is investigated.
