Abstract
Cross-sectional barriers in rivers cause, among others, an impact on the longitudinal connectivity of river ecosystems. It is frequent to build fish passes to palliate this impact and to enable free movements of the fauna (especially fish). However, even though they have been massively built during the last decades, their functionality has been scarcely assessed. Duero River Authority (Confederación Hidrográfica del Duero), Ecohydraulic Applied Group (GEA) of the University of Valladolid and Itagra.ct have developed a new assessment methodology of the functionality of stepped fish passes (Methodology AEPS). This methodology has been tested in 50 of these structures. It analyzes the suitability of the fish passes for target species attending to design parameters and eco-hydraulic aspects. It can be used in different areas and for different species with minor modifications. Its implementation has allowed to know the current situation of the fish passes in the Duero River basin, identifying their problems and how to solve them.
