Rhone-Thur Project

Many Swiss rivers have been channelized, straightened and regulated over the last 150 years. These impacts have led to the ecological degradation of rivers and streams. Furthermore, channelized rivers often no longer provide adequate protection against floods. River restoration should therefore improve flood protection and restore the ecological diversity of rivers, their ecosystem functions, and their scenic attributes. The Rhone-Thur project aimed to scientifically accompany and support restoration measures, with a special focus on local river widening on the Rhone and the Thur River. An important focus was on monitoring and evaluation and decision-making. Monitoring and evaluation is important because it can be used to assess the effects of restoration measures on the ecosystem and local populations. Decision-making studies showed how important stakeholders can be involved in the planning process. On the Rhone River, an additional focus was on hydropeaking.

With diverse ecological, physico-chemical and socio-economic studies, practical insights were gained for future restoration projects in Switzerland and abroad.
