Abstract: An experimental multidisciplinary study was applied to three watersheds inside the national park of Belluno Dolomites (Veneto region, Northern Italy) to verify experimentally the hydrological and ecological effects on river base-flow regime and fluvial functionality of water abstraction for energy supply. For a total of 15 sites (13river sections and 2 main head-water springs), located upstream and downstream of main water abstraction plants, a hydrological (whole year) and ecological (growing season) monitoring scheme has been applied during 2006-2007. Minimum Acceptable Flow (MAF) was calculated through different empirical and analytical tools and compared with monitoring results. A high resilience of river ecosystems in response to water abstraction was highlighted; indeed major ecological effects were due to other factors, either of anthropic (preventing erosion weirs) or natural (geomorphology of river bed) origin.
