Abstract: Located at the interface between the marine and terrestrial environment, coastal wetlands are important nature-based solutions providing a buffer against storms action and other important ecosystem services such as carbon sequestration and provision of recreational areas. A variety of natural processes continuously shape wetlands morphology and sediments dynamics regulating coastlines resilience to sea-level rise and environmental change. Understanding variations in sediment transport patterns across the coastal system is important to determine the susceptibility of the coastline to environmental change. Particularly, a positive sediment budget is relevant for the survival of coastal wetlands to sea-level rise. In this article, I present preliminary results about a modelling setup and use for the evaluation of sediment transport and water level propagation across Morecambe Bay. The area is located NW of England and is a macrotidal system of large interest from an economic and environmental perspective because of the dynamicity of wetlands in the area.
