Erosion and Storm surges related to extreme conditions and sea level rise, are the main identified coastal risks. Despite the need for more data and knowledge about those risks, it remains extremely difficult to get systematic data collection at the coast before, during and after an extreme event. Existing beachcams can be very useful in this respect. Meteo/climate forecasters already use existing beachcams to get a visual check of the sea state at the coast on one specific beach.
The aim of this project is to go further, and first, to gather the visual information all along the year from a set of a dozen existing cameras from Viewsurf and Beachcam networks, along the western european coast. Then, the expertise on coastal video monitoring of Waves’n See will be used to extract key coastal parameters from coastline or sea state to overtopping. These parameters enable to have better understanding of a beach response to successive meteo-
oceanographic events, and are therefore useful to optimize the decisions and actions of beach managers. Additionnally, they constitute relevant validation or input data to ocean modellers.
