Assessing impacts of dam operations: interdisciplinary approaches for sustainable regulated river management

A special session of the European Geosciences Union General Assembly held in Vienna on 2–7 May 2010 was dedicated to the assessment of the impacts of hydropeaking, definition and implementation of environmental flows, implementation of experimental releases and flushing floods and proposal of mitigation measures, including dam removal and dam re-operation. This special issue contributes to the understanding of consequences of dam operations, promoting interdisciplinary works in the ecohydrology field and stimulating scientific exchange between ecologists, hydrologists, geomorphologists, engineers and end-users to develop a unified view of the problems of flow regulation below dams.
