%X Although there are numerous case studies assessing coastal vulnerability, many of these studies have been performed in places where notable efforts have been carried out to provide informa-tion on the different variables that affect the coast. However, this is not the case for most places worldwide given the lack of long-term datasets. This study makes use of information from satel-lite remote sensing and analytical models to derive two vulnerability indices along a 9.5 km stretch of the coast of Langue de Barbarie, Saint Louis, Senegal (Western Africa). The first is a coastal vulnerability index (CVI) to sea level rise due to climate change and results in a five -category classification: Very Low, Low, Moderate, High, and Very High. The second is a flood vul-nerability index (FVI) to coastal flooding due to extreme events and results in a three-category classification: Low, Moderate, and High. Results for the CVI index show that 70% of the coast pre-sents High and Very High vulnerability values, largely located in the most densely populated ar-eas. The FVI is assessed for one of the most energetic storms for the 1979-2021 period which oc-curred in February 2018 using a beach configuration of March 2021. Results show that 29% of the coastline presents High FVI values (i.e., are likely to be overtopped) concentrated in the cen-tral sector of the most-populated districts. This provides relevant tools to improve coastal man-agement when in situ data are not available.
