CNEXO experimental SandPit in Seine Estuary

Introduction

Through the sixty’s, needs of sands and gravels quickly increased and several studies were carried out by Cnexo (former name of Ifremer Institute) on substitution materials to prevent problems of material supply. In order to study responses of exploitation of submarine materials, a full-scale experiment was launched in 1973 on a site located at the mouth of the Seine estuary. Morphodynamic behavior of CNEXO pit was studied within SANDPIT European FP5 project.
