Understanding the resilience of coastal systems in a changing climate is key to support the transition from traditional management towards more sustainable planning. This work describes a pilot methodology developed and applied to quantify a Coastal Resilience Index (CRI) for a 2 km sand dune system at Nairn in North-East Scotland.

This paper summarises the findings of using two distinct methodologies to represent mangrove structures in a numerical wave tank (NWT) within the framework of a CFD model. The work is the first phase of a larger project that aims to improve the parametrisation of mangroves in reduced-dimension, 2D-Horizontal (2DH), coastal area models; specifically, long wave models. The primary goal is to determine approaches to best parameterise the effects of both added mass (inertia) and drag forces, based on the properties of individual mangroves and the hydrodynamic conditions (i.e. water depths and velocities).
