A guide to modeling coastal morphology Process based morphodynamic Modeling is one of the relatively new tools at the disposal of coastal scientists engineers and managers. On paper it offers the possibility to analyse morphological processes and to investigate the effects of various measures one might consider to alleviate some problems. For these to be applied in practice a model should be relatively straightforward to set up. It should be accurate enough to represent the details of interest it should run long enough and robustly to see the real effects happen and the physical processes represented in such a way that the sediment generally goes in the right direction at the right rate. Next practitioners must be able to judge if the patterns and outcomes of the model are realistic and finally translate these colour pictures and vector plots to integrated parameters that are relevant to the client or end user. In a nutshell this book provides an in depth review of ways to model coastal processes including many hands on exercises.
