The impact of rain events on the supply and movement of fine sediment in engineered intertidal systems

Low-tide rainfall events can strongly influence sediment dynamics in intertidal systems, but their role remains understudied, especially in engineered environments such as Managed Realignment (MR) sites. This research investigates how natural precipitation influences suspended sediment concentrations (SSC), bed elevation, and sediment fate at Pagham Harbour, a historic unManaged Realignment (uMR) site on the south coast of the UK. The presence of tidal flaps controlling freshwater input at this
