This reference for engineers, and graduate students covers sediment transport and morphodynamics modelling in nearshore environments. It presents the fundamentals required for understanding the physics and for setting up numerical models. This book covers hydrodynamics of estuarine and coastal environments, properties of seafloor and estuarine composition, and hydroenvironmental interactions; emphasising the inter-relations of small- and large-scale processes, and short- and large-evolution timescales. The focus is, principally, on the application of shallow-water theory, but some surface wave models, and coupling of shallow-water models with surface waves is also discussed to some extent. The guidance on running regional models and the case studies presented are directed to managed realignment, coastal protection, climate change impacts, and offshore renewables.
