Larger-scale morphodynamic impacts of segmented shore-parallel breakwaters on coasts and beaches: an overview of the LEACOAST2 Project

Abstract

This paper presents an overview of the LEACOAST2 research project, studying the large-scale morphological impacts of nearshore flood defense structures (shoreparallel breakwaters) on coasts and beaches. The project uses a study site at Sea Palling, Norfolk, UK, where nine segmented shore-parallel breakwaters are present, to conduct detailed field measurements, regularly bathymetric surveys, and long-term remote-sensing monitoring. Both process-based and probabilistic models are applied to the site to investigate the beach response to the nearshore structures for short-term storm conditions and longer-term macro-tidal conditions. The paper also highlights the key findings obtained from the projec
