Salt marsh and mangrove vegetation, which cover ~19% of our global coastline, are paramount in helping to reduce climate change-related risks along the coastline. Particularly when used in combination with other natural or man-made coastal defences, belts of coastal vegetation can help reduce damage and associated costs from waves, intense storms, tsunamis, erosion and sea-level rise.
To better support coastal zone management planning and coastal defence initiatives, MIKE 21 Flow Model FM, MIKE 3 Flow Model FM and MIKE 3 Wave FM models can now be used for a variety of vegetation – from rigid plants like mangroves to flexible plants such as salt marsh cover. In addition, MIKE 21 Spectral Wave FM also includes two new dissipation models for rigid plants: a multi-layered approach for the fully spectral formulation and directionally decoupled parametric formulation and a single-layered approach for the fully spectral formulation.
