Nearshore modelling of longshore sediment transport in the application to climate change studies at Ninety Mile beach, Australia

Understanding changes in the shoreline is important information used to support the planning of coastal mitigation, particularly under the influence of anthropogenic climate change. It is shown that Lakes Entrance, a township located at the northern end of Ninety Mile Beach in south-eastern Australia, is situated in a region that may experience noticeable future changes in longshore winds, waves and currents, which could alter the supply of sediments to the shoreline. Global Climate Model simulations are downscaled with a basic empirical equation and a comprehensive coastal-area numerical model to investigate the longshore transport climate of a high greenhouse gas future.
