Abstract: Several restoration measures are planned for the Enz, the longest left tributary of the Neckar, Germany. These include river widening, groynes, and flow concentrations. Due to the location of these measures in the downstream area of a hydroelectric power plant, it is necessary to clarify the extent to which a possible rise in the water level resulting from the conversion measures could affect energy production. Since 1D and 2D approaches are not ideal for detailed investigations involving local disturbance zones, a 3D simulation tool must be used for the assessment. FLOW-3D HYDRO was used to determine the impact of the planned measure on the water level in the downstream area of the power plant. The potential impact of individual measures on water level changes can also be analysed. The investigation reviews the overall measure's effectiveness in creating habitats and assesses its impact on the upstream hydroelectric power plant.
