Hydromorphological investigations of different approaches to improve the ecological state of the lower Ems river

IIn this project four alternative solutions are analyzed with respect to their potential to sustainably reduce the sediment import into the river Ems and to improve the water quality in the lower river. A three dimensional hydrodynamic numerical model is applied to conduct hydromorphological simulations. The results are used in conjunction with an verified set of indicators to evaluate the proposed solutions against the actual situation.
