Estimating coastal flooding

Created by CLS to help coastal areas reduce their vulnerability to rising sea levels, the interactive LITTOSCOPE interface allows users to visualise several scenarios of rising sea levels, with or without a ten-year storm.

The tool also offers an assessment of the impacts (human, economic, heritage, environmental) generated.

Forecasting cyclonic coastal flooding

Tested in the Bengal delta, the Band-SOS demonstrator is a pre-operational service for a coastal flood forecasting platform based on multispectral satellite images (Copernicus Sentinel-2). In operation since January 2023, the tool is used daily by the Bangladesh Flood Forecasting and Warning Center (FFWC).

Band-SOS provides a real-time forecast of the risk of flooding when a tropical cyclone strikes the coastline, coupled with a map of the vulnerability of populations at risk.

Improving coastal governance

Developed by the company BlueCham on Tahiti and a Tuamotu atoll (Tahatai project), the Qehnelo®PF platform offers new digital resources for the governance of the coastal zone, a privileged place for exchanges between land and sea parties. The interface displays three indicators: water quality, anthropogenic pressures in the lagoon environment (including automatic boat detection) and anthropogenic pressures on the coastline (land use).

Development is continuing through the Tahatai Neo project to deploy the system throughout Polynesia and then internationally.

Assessing the vulnerability of coastal populations and economic activities

Developed for the city of St Louis in Senegal and replicable for other coastal areas, the SCO St Louis interface combines all types of data to estimate the socio-economic vulnerability of coastal cities to the effects of climate change and raise awareness among local players.

The mapping platform can be used to select and combine several layers of information, including historical floods, land use and essential infrastructure, as well as simulations of marine and river flooding according to different IPCC scenarios.
