L’entretien des cours d’eau génère des volumes conséquents de sédiments, qui, en zones urbanisées, sont souvent contaminés en métaux. Une fois curés, ces sédiments sont déposés à terre de façon pérenne ou transitoire ; se pose alors la question de leur impact environnemental. L’objectif de ce travail était d’évaluer l’évolution du potentiel mobilisable de métaux et les paramètres en jeu dans le vieillissement des dépôts. Ce dernier a été simulé en conditions contrôlées au laboratoire à l’aide de deux protocoles de vieillissement : le premier visant à simuler un dépôt en conditions drainantes, le second en conditions hydromorphes. La mise en solution des métaux et l’évolution de leur distribution dans les compartiments de la phase solide ont...
