To study temporary rivers’ hydrology and ecology, to create new tools to improve their management and to facilitate decision making considering the EU Water Framework Directive (WFD) are the main objectives of the European project LIFE Trivers, an initiative fostered by a consortium led by Professor Narcís Prat, from the Department of Ecology at the University of Barcelona (UB). The Institute of Environmental Assessment and Water Research (IDAEA-CSIC), the Catalan Water Agency (ACA) and the Júcar Hydrographic Confederation (CHJ) also participate in the project. Tools will be developed considering the results obtained by researchers involved in the project MIRAGE —which is part of the Seventh European Framework Programme in order to provide water managers and citizens with scientific knowledge.
