The project, which resulted from the implementation agreement between the Po River District Authority, the Piedmont Region and the Po River Interregional Agency, involves the lowland section of the Pellice River, with a length of about 25 km. The project works fall within the Win-Win integrated interventions, i.e., they are able to simultaneously guarantee the reduction of hydrogeological risk, the improvement of the ecological status of watercourses and the protection of ecosystems and biodiversity, allowing the objectives set by the Water Management Plan (PdGPo), implementing Directive 2000/60 EC, and those set by the Flood Risk Management Plan (FMP), implementing Directive 2007/60 EC, to be achieved in an integrated way.
One- and two-dimensional hydraulic modeling of the Pellice stream in its actual and project state was used to define the necessary works.
The identified interventions, spread along the entire Pellice River shaft, are as follows:
- Intervention 1: Reactivation of secondary branches, bank defenses and forest conversion in the Municipalities of Bricherasio, Garzigliana and Cavour;
- Intervention 2: Bank defense, enhancement of existing defense and opening secondary branch in the Municipalities of Garzigliana and Cavour;
- Intervention 3: Reprofiling and reshaping existing natural branch in the Municipality of Cavour;
- Intervention 4: Widening of outflow section at the confluence with the Chisone Stream in the Municipality of Cavour;
- Intervention 5: Redevelopment and reconnection of the former quarry in Località Zucchea in the Municipality of Villafranca Piemonte;
- Intervention 6: Bank defense and secondary branch reactivation in the Municipalities of Vigone and Villafranca Piemonte;
- Intervention 7: Strengthening and reconnection of the Bosco Tetti Girone resurgence in the Municipalities of Vigone and Villafranca Piemonte;
- Intervention 8: Reinforcement of hydraulic defense built-up areas of Ruata Pellice and Mottura in the Municipality of Villafranca Piemonte;
- Intervention 9: Bank defense, secondary branch opening and environmental rehabilitation in the Municipality of Villafranca Piemonte.
