Abstract

The application of an interdisciplinary approach to river management in some fluvial environments is presented. Three large rivers in Mediterranean climate have been studied: Russian River in northern California (drainage area of 3,846 km2), Ebro River in northeastern Spain (85,530 km2) and Volturno River (5,550 km2) in southern Italy. The aim is to compare hydrological and geomorphic features to highlight natural and human-based evolution, considering climatic crises and river basin management in the last decades. Moreover, improvement strategies held in the last years to increase their ecological status and to reduce pressures on hydromorphological attributes are analyzed. These rivers have been facing increasing changes in hydrogeomorphic aspects, mainly due to river damming, coastal retreat and floodplain occupation. These changes have deeply altered the fluvial dynamics, modifying aquatic and riparian habitats and imposing large alterations in their ecomorphological connectivity. However, they are being actively managed nowadays to improve their ecohydrological status: habitat restoration for protected species and amelioration of flow regime in Russian River, improvement of river connectivity and reduction of hydrologic alteration in Ebro River, river banks and mouth recovery to reduce erosion in Volturno River are some of those strategies. Application of these tools shows that an integrated, adaptive approach suitable for Mediterranean rivers improves their ecological status restoring natural processes.
