Hydrogeomorphology-ecology interactions in river systems

The European Union-funded REFORM (REstoring rivers FOR effective catchment Management) project has developed guidance and tools aimed at making river restoration and mitigation measures more effective. A major component of this work has been to investigate functional linkages between the hydrogeomorphology and ecology of rivers. This special collection presents some of the outputs from this work concerning interactions between hydrological, geomorphological and ecological processes in naturally functioning river systems. Together, this set of five papers reviews some of the existing knowledge on interactions and feedbacks between hydrogeomorphology and ecology in river systems and outlines how hydrogeomorphological processes, ecological processes and plant traits contribute to driving river corridor dynamics that create and sustain a diversity of aquatic and wetland habitats that support fish communities.
