Climate Change Adaption in Mon Choisy, Mauritius
eCoast conducted a comprehensive study on the physical processes in play at Mon Choisy, Mauritius.
Mon Choisy is a popular destination in Mauritius for locals and tourists alike. The beach, fronted by a shallow lagoon extending to the outer reef, suffers from chronic erosion at its southern end. Sea level rise and cyclone activity have the potential to erode the beach further threatening infrastructure an the loss of a valuable public amenity. eCoast conducted a comprehensive study on the physical processes in play at Mon Choisy incorporating field data collection, numerical modelling of waves and rides and an assessment of extreme events. The recommendation for the site comprises a hybrid approach involving soft and hard engineering solutions such as beach nourishment, beach re-profiling, dune management and better management of beach and lagoon activities. Additionally, a series of low crested and submerged reef structures offshore of the southern section will help to reduce incident wave energy and slow the rate of northerly sediment transport along the beach.
