Estimation of extreme water level values – Metropolitan coast, 2022 edition
Description
This study is a first global estimate of the extreme water level values along the metropolitan coastline. It is to be refined locally with all available data and knowledge.
The method used is based on a statistical analysis of the tide charts available in ports. It does not take into account the observations of the waves. The results between ports are obtained by an interpolation method.
The study produces statistical estimates at reference ports:
— extreme values of open sea overcots in the Channel and Atlantic;
— extreme water level values for the entire metropolis.
And a set of statistical estimation maps of extreme water levels along the coastline.
The estimates provided go up to the return period 1000 years. In view of the observation times used at ports, the user must check whether the estimates of a return period of more than 50 or 100 years still make sense.
