IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

ABSTRACT
In the last decades in Europe, the importance of renewable energy is increasing since it could help to mitigate carbon
dioxide emissions and to reduce the fossil fuel dependence of European Member States (Directive 2009/28/EC). In the
European Alpine region, the main renewable source of energy is hydropower. On the other hand, one of the priorities of
the Water Frame Directive (Directive 2000/60/EC) is water protection. The Alpine Space project "recharge.green-
Balancing Alpine Energy and Nature" focuses on the trade-off between energy production and the pressures on nature. In
this project, we develop a decision support system (DSS) that considers legal, technical, economic and recommended
constraints of both the directives in order to evaluate the residual potential of rivers. The model is developed in GRASS
GIS software and is a multi-disciplinary tool that, starting from water availability and elevation data, provides first
information on the theoretical potential. Secondly, the existing plants and the different uses of water are considered. The
mandatory provisions (i.e. the environmental flow, parks, etc.) and the technical constrains (plant efficiency, type of
turbine, etc.) reduce the number of exploitable rivers. The model is applied to the area of Gesso and Vermenagna basins
in the north west of Italy, in Piedmont Region. The potential sites obtained by the DSS have been analyzed and different
scenarios compared. We obtain a panel of different solutions depending on the optimization choices. In conclusion, this
decision support system can be a very important multi-disciplinary tool to support planning in the complex alpine area
territory and to find possible alternative energy solutions by taking into account the landscape and the environment.
