Riverscape – sediment dynamics and connectivity

The research project ‘Riverscape – sediment dynamics and connectivity’ combines the topics of hydraulic engineering and ecology. Researchers have worked together to establish fundamental principles and propose solutions for the restoration of sediment dynamics and habitat connectivity. The most important results relevant to practice are presented in this publication.
