In a context of old and heterogeneous buried canals having to collectively share the ressource and face scarcity, the members of the water rights management commission were led to set an innovative framework to improve water management and progress in participatory optimal water allocation. Saving water is indeed possible when resources issues are well monitored and anticipated, when workforce for on site control is increased and water withdrawal techniques are properly implemented and monitored.

The proposed solution aims to contribute for mapping the way forward the sustainability of the small hydropower (SHP) sector in the European Union (EU), as an important contributor for both penetration of a clean and secure energy source and a way toward an integrated management of water resources.

The Stream Map is a first attempt to establish a wide contact network for bringing together the main actors and target groups of the sector. Through the data collected and free access as well as through the contacts established it is possible to start producing the state of the art of the sector and a Roadmap for the development of a sustainable SHP sector and key recommendations for the future, with a view of harmonizing the targets established by the Renewable Energy Sources (RES) and Water Framework Directives (WFD) within EU.

SHARE, sustainable hydropower in Alpine rivers ecosystems

This European project is a technical solution to harmonize energy and water through its mission, “making sustainable hydropower a reality”: Administrators of mountain areas daily face water use issues and have to take decisions in relation to them. But they lack reliable management tools tailored to mountain rivers, to rigorously evaluate the effects of water abstraction on environment and on society.

Rivers without Boundaries (RwB) International Coalition is developing relatively simple, but comprehensive express-assessment method that allows to compare basin-wide environmental impacts of various water infrastructure development scenarios. Methodology is based on semi-quantitative assessment of cumulative impacts of flow alteration, basin fragmentation and creation of anthropogenic water reservoir in place of natural river ecosystem. We analyze how these impacts from one or several dams affect known environmental values in a given river basin. All measures of impact we use were suggested in scientific literature and our innovation is in combining them in one effective and transparent assessment tool, that could be customized and adapted according to situation in a given basin under assessment. Assessment results also allow to compare how much impact is caused per unit of produced energy providing a rough measure of ecological efficiency.

The SHARE-Alpine space project is developing, testing and promoting a decision support tool based on a multicriteria analysis. This approach take into account, on a quantitative basis, the functioning of water associated ecosystems and hydropower production needs, and seek to conciliate them.

IWRM applied to the renewal of hydropower concessions

One river is often equiped with multiple hydropower infrastructures. These infrastructures are deeply interdependent: downstream hydropower plants highly depend on the water flow from downstream infrastructures. Taking this situation into account, efficiency suggests that infrastructure located in the same basin be managed by a single institution, holding all the concessions of a given hydraulic chain. However, until now, it has rarely been the case.
