About the Book

Rivers form one of the lifelines in our society by providing essential services such as availability of fresh water, navigation, energy, ecosystem services, and flood conveyance. Because of this essential role, mankind has interfered continuously in order to benefit most and at the same time avoid adverse consequences such as flood risk and droughts. This has resulted in often highly engineered rivers with a narrow set of functions. In the last decades rivers are increasingly considered in a more holistic manner as a system with a multitude of interdependent processes. River research and engineering has therefore added to the river fundamentals also themes like ecohydraulics, consequences of climate change, and urbanisation.

River Flow 2020 contains the contributions presented at the 10^th conference on Fluvial Hydraulics, River Flow 2020, organised under the auspices of the Committee on Fluvial Hydraulics of the International Association for Hydro-Environment Engineering and Research (IAHR). What should have been a lively physical gathering of researchers, students and practitioners, was converted into an online event as the COVID-19 pandemic hindered international travelling and large gatherings of people. Nevertheless, the fluvial hydraulics community showed their interest and to be very much alive with a high number of participations for such event. Since its first edition in 2002, in Louvain-la-Neuve, this series of conferences has found a large and loyal audience in the river research and engineering community while being also attractive to the new researchers and young professionals. This is highlighted by the large number of contributions applying for the Coleman award for young researchers, and also by the number of applications and attendants to the Master Classes which are aimed at young researchers and students.

River Flow 2020 aims to provide an updated overview of the ongoing research in this wide range of topics, and contains five major themes which are focus of research in the fluvial environment: river fundamentals, the digital river, the healthy river, extreme events and rivers under pressure. Other highlights of River Flow 2020 include the substantial number of interdisciplinary subthemes and sessions of special interest. The contributions will therefore be of interest to academics in hydraulics, hydrology and environmental engineering as well as practitioners that would like to be updated about the newest findings and hot themes in river research and engineering.

About the Author: 1. Wim Uijttewaal, is a professor of experimental hydraulics at Delft University of Technology. He has more than 25 years of experience in research on shallow flow turbulence as well as the more generic hydraulic engineering topics, such as sediment transport and scour, interaction of waves and currents with vegetation, flows in embayments and groyne fields and fluid-structure interaction. He published over a hundred peer-review papers in high-ranked journals, initiated the series of conferences on Shallow flows in 2003 and contributed as co-organiser to a number of IAHR and Euromech conferences. 2. Mário Franca is Professor of Hydraulic Engineering for River Basin Development at IHE Delft Institute for Water Education and at the Delft University of Technology, the Netherlands. Before joining IHE Delft, Mario held academic positions at EPF Lausanne, New University of Lisbon and University of Coimbra. He worked for several years as consultant in hydraulic engineering. His research interests include turbulent processes in open channel flows; fluvial geomorphology and sediment transport; density currents; non-conventional and sustainable hydropower. He is an active member of IAHR and was part of the organizing committees of River Flow 2006 and 2014. He is associate editor of Water Resources Research (AGU) since 2016. 3. Daniel Valero holds a Civil Engineering degree (Master level) from the Universitat Politecnica de Valencia (Spain), from where he also obtained a Master's Degree in Hydraulic Engineering and Environment. He obtained his PhD at the Universite de Liege (Belgium) and worked in Aachen University of Applied Sciences (Germany), where he gained experimental and numerical modelling experience on multiphase flows. His main expertise is related to the fluid mechanics with a special focus on areas such as air-water flows and energy dissipation. His works have also advanced knowledge on multiphase flows instrumentation through the use of robust filtering and computer vision techniques. He has also participated in the organisation of several IAHR events. 4. Victor Chavarrias is an engineer and researcher in Deltares. He obtained his PhD in mathematical modelling of river morphodynamics in the Delft University of Technology 5. Clàudia Ylla Arbós is a PhD candidate at Delft University of Technology. She studied Civil Engineering at the Polytechnic University of Catalonia (UPC BarcelonaTech) and the Swiss Federal Institute of Technology (EPFL), specializing in Hydraulic and Geotechnical engineering. After experimental work on wave-structure interaction at EPFL, as well as consulting work in Switzerland, her current PhD research focuses on the long-term, large-scale morphodynamic response of the lower Rhine River to human intervention and climate change. 6. Ralph Schielen is senior expert on river management, focussing on hydraulic and morphological development of lowland river systems and is working at the Dutch Ministry for Infrastructure and Water Management-Rijkswaterstaat. He is also affiliated with Delft University of Technology. Within Rijkswaterstaat, he is PI of a large research programme Rivers2Morrow, where several universities combine research on hydraulic engineering, morphology and sediment management. Aim is to facilitate and improve Operations and Maintenance at Rijkswaterstaat, and contribute to long term policy development on river management. His own research interests include side channels dynamics, stability of river bifurcations, long term morphological development of lowland river systems and application of Natural and Nature Based Features for flood management. 7. Alessandra Crosato holds the position of associate professor of river morphology and river engineering at IHE Delft Institute for Water Education and is a research associate at the Delft University of Technology, the Netherlands. She has more than 20 years of experience in research and consultancy projects dealing with the morphological response of aquatic systems, for which she studies the effects of the interaction between water, sediment, vegetation and human interventions. Dr. Crosato has produced more than hundred publications in international journals and conference proceedings. She teaches graduate courses on river training, river restoration, river morphodynamics, numerical modelling, river bio-geomorphology and dam effects on rivers.
