UNESCO/IHE - Rapid assessment of climate change on inlet-interrupted coasts

Most coastlines around the world are interrupted by inlets connecting the ocean to estuaries, lagoons, and rivers. Coastlines in the vicinity of inlets will be affected not only by climate change driven variations in oceanic processes (e.g. sea level rise) but also by climate change-driven variations in terrestrial processes (e.g. rainfall/ runoff). The combination of their sensitivity to several climate change-driven variations in system forcing and their heavy human utilisation renders the thousands of inlet-interrupted coasts around the world highly vulnerable to climate change impacts. UNESCO-IHE has developed an innovative, easy-to-use mathematical model (SMIC-Scale aggregated Model for Inlet interrupted Coasts) to obtain estimates of local scale (< 25 km alongshore) coastline change due to all relevant climate change impacts. Model applications in four representative systems show that methods historically used to assess coastline response to climate change may be under-predicting potential coastline recession by up to 50-75%.
