About

ediment exchange between the beach and the inner shelf is currently not well understood. Most studies in the literature suggest that wave driven cross-shelf sediment transport is the only agent to supply sediment to the inner shelf. Beach monitoring studies have revealed that significant sediment exchange exists between the intertidal beach and the inner shelf during extreme events, demonstrating that nearshore / offshore sediments cycle on beaches does not constitute a closed system within embayed coasts. All these studies show evidence of sediment transport seaward of the surf zone, but do not focus on the key driving processes, quantification, or whether they are associated with storm events. Combining observations of wave-currents interactions and sediment budgets together with numerical simulations of sediment transport for the macrotidal high energetic beach of Perranporth, we aim to understand the dynamics governing the sediment exchange beyond the beach system.
