Abstract
Coastal ocean regions around the world are hubs of transportation, zones of rich mineral resources, fisheries and recreation, and home to billions of people and diverse ecosystems. Many such regions are threatened by a variety of factors and the increasing risk and associated impacts have catalysed efforts to increase our understanding of the coastal ocean environment and our ability to make quantitative predictions of coastal hydrodynamics. Accurate modelling of coastal ocean processes requires mathematical models which go beyond the traditional shallow water equations. In addition, understanding the true impacts of processes such as sea-level rise and severe storms requires coupling such models with transport models of sediment erosion/deposition. In this project, we propose to build a numerical code based on hybridised discontinuous finite element methods for studying complex coastal hydrodynamics and sediment erosion with specific emphasis on regions of the Texas-U.S. and Portuguese coasts.
