Cross-shore profile models

Abstract This paper aims at describing the state of the art in modelling of cross-shore profile evolution. After a discussion of various classes of models concepts, attention is focused on process-based models. Various transport concepts used in process-based models are compared in relation with the dominant processes to be modelled. The demands on the hydrodynamic components of the models are discussed, and available hydrodynamic models are evaluated in this context. Results are presented of an intercomparison of five morphodynamic models operational in Europe, in the framework of MAST-G6M. Individual strong points and common weak spots are identified. The latter lead to recommendations on further research.
