Seasonal and intraseasonal variations from the top to the bottom of a beach profile can be considerable. The shape of a beach profile influences greatly its ability to resist to the waves’ attacks. Therefore, this is a crucial morphological parameter to take into account in marine submersion studies.
Wavecams® technology enables a high frequency monitoring of beach profiles from coastline detections. Here is an example in Etretat bay, with beach profiles computed every 10 days from January 2018 to July 2021. Beach profiles vary constantly, and some large modifications happen, specifically during winter storms in 2019 and 2020.
