Abstract: This paper discusses the role of morphological modelling in support of environmental impact assessments, based on recent experiences in the Netherlands. An overview of the state-of-the-art in morphological modelling is presented first. Traditionally, morphological modelling has been applied in analyzing erosion and sedimentation problems and to evaluate management options. In our recent experience, the most important and most demanding use of morphological models has been to support ecological evaluations of the impact of large-scale land reclamations or dredging strategies, which require different parameters and therefore different approaches.

Keywords: Morphological modelling, land reclamation, dredging strategy, sand mining.
