Groundwater simulations for the Inn-revitalisation project

The impact on the actual groundwater flow situation is beside the ecological, structural and morphological aspects, a major keypoint of a river revitalisation plan. A change of the current river sole position, the wetted river width, the water level or the riverbed permeability can influence the water exchange between the river and the aquifer. In a close range this might lead to a strong ground water level decrease or increase.

In the framework of the 2nd stage of the Inn-revitalisation project in the community Bever in the Upper Engadine, that will be realized in the next months (https://www.innauen.ch/), the impact on the groundwater situation has been evaluated on the basis of the 3D groundwater model Upper Engadine, calibrated and maintained by TK CONSULT AG. In collaboration with the planners (Eichenberger Revital, Hunziker, Zarn + Partner, ecowert) and the hydrogeologist (Sieber, Cassina + Handke) measures to regulate the groundwater table have been additionaly developed.
