Description

The OVERCOME project is an applied research project that aims to provide the dam and dike engineering profession with an easy-to-use, physically based numerical tool that represents overtopping erosion and failure of homogeneous embankments made up of coarse-grained, gap-graded soils. This project began in 2018 and is scheduled for completion in 2028, and was initiated by EDF and CNR, who are the two main owners of embankment dams in France. To achieve this objective, the OVERCOME project is based on an extensive program of experimental tests of various dimensions. The interpretation of these tests will be used to define a numerical model that will be implemented in the TELEMAC 2D open-source code. This numerical model will be validated on the basis of large-scale tests. This article presents an overview of the project's progress, and then focuses on two major issues: the evaluation of a method for LIDAR measurement of the evolution of the geometry of the downstream face of the embankment during erosion tests, and the characterization of the erosion resistance parameters of coarse-grained soils with spread granulometry using the Jet Erosion Test.
