The ecology of the river Rhône has been largely impacted by human interventions, with the channelisation of the river and the constructions of dams, dikes and bendway weirs for fluvial navigation. The solution consists in the restoration of oxbows, in the increase of minimum flow rates within controlled reaches and in the construction of fish pass to restore fish migrations and fish habitats.

River restoration on an old industrial site by regrouping of the various water discharges in one point for treatment  and by reconstructing the morphology of the river. The solution was primed for the Loire Bretagne Water Awards. The industrial site was developed on the bed of the river la Viouze. 6 outlets are discharging directly in the river.The river was flowing trough 2 decantation basins used to clarify a part of the water discharged by the industry. The basins were also used as a tank to produce industrial water.

Within the ScaldWIN project (an Interreg IVB NWE project), the objective of the first work package entitled “Improving the ecological status of surface water bodies based on river ecosystem development and enhancement of biodiversity” (WP1)  is to contribute to the improvement of the ecological status of surface water bodies by jointly planning, implementing and evaluating a number of cost-effective and transnational actions concerning river ecosystem development. Different types of river ecosystem development projects will be implemented, which are often favourable to river continuity and hence fish migration (biodiversity), and a transnational inventory of fish migration barriers will be made up. By monitoring before and after the implementation of these transnational actions, the effect of river ecosystem development on the ecological status can be assessed. The transnational actions will also help define indicators which are best suited to assess effects and benefits of river ecosystem development measures.

About 18,000 small dams(weirs) are located across the streams in Korea and about50~150 small dams are abandoned annually. This study is  to develop the technology for restoring the stream eco-corridors by removing the small dams whose functions have been lost, and improve the water quality deteriorated by the small dams.
