How coastal wetlands help protect from flooding

Caption

Map showing the difference in water level between scenarios where marsh was present or absent at the Three Rivers estuary complex in South Wales. Red areas indicate large reductions in water level where marsh is present, and blue-white where little to no effect was observed, showing that the presence of marsh vegetation has the greatest flood protective effect for towns and infrastructure in upstream areas
