Navigational depths in an entrance area of a port with severe sedimentation are predicted by a novel model, which combines 2D morphological modelling in the port areas and shoreline morphological modelling of the adjacent coastlines. The model simulations demonstrate the strength in treating the long uniform stretches differently from the more local and complicated morphology and to couple the two model strategies in a single model. The principle is strong and can be used in any case where local complex morphology affects the alongshore sediment budget and vice versa (coastal structures, headlands, submerged reefs, etc.).
