Study of dune dynamics on the French continental plate
Period : First stage : 2005 to 2009 ; Second Stage : 2013-2017
- Purpose
-
The aim of the project is to determine and to map the sectors affected by shifting dunes and sandbanks on the French continental plate. It also aims to improve and ensure navigation safety, to improve hydrographic readings, to improve methods for researching buried objects, to record sand stocks and their dynamics, and to study the impact of the phenomenon on the propagation of acoustic waves.
An inventory of bathymetric reading and the bibliography were conducted in order to determine areas with sandbanks or dunes in order to map them in a GIS.
The different morphological dune parameters are defined using semi-automatic software developed by the SHOM and the RMS.
This software is based on the use of high-resolution bathymetric data from multi-beam echosounders in the following order:
- bathymetry is analysed in order to establish a digital terrain model(DTM)
- the software draws the contour of the structures it meets and demarcates the different dunes which may be refined by the operator.
The projects include the following tasks:
- to establish the state of knowledge regarding dune dynamics, and organise Marid conferences;
- to list the available data and improve knowledge of the French metropolitan plate;
- to characterise the impact of dune dynamics for all applications;
- to improve hydrographic recording methods in dune areas;
- to identify and monitor dunes which could be dangerous to navigation;
- to develop a “Dunes” database;
