PhD position “The impact of nature-based solutions on hydrodynamic and morphodynamic processes in small rivers”

Western Europe and other parts of the world seem to experience more severe floods and droughts recently. These extreme events are not random, but are the manifestation of a changing climate. As a result, such events are anticipated to occur more frequently compared to the past. To reduce the impact of these extreme events, measures in river systems are needed to ensure flood safety and the availability of water for irrigation, navigation and other uses. To enhance water conveyance and water retention in rivers and at the same time restore the ecosystem functions of rivers, the Building with Nature (BwN) concept is often used. BwN promotes the utilization of natural processes to create a resilient water infrastructure that simultaneously satisfies societal and ecosystem needs. Such nature-based solutions include creating space for water retention and periodic flooding, re-meandering of straightened river sections, increasing flow resistance by promoting vegetation growth, which also improves water quality, and installing natural structures such as dead wood, which increases the flow variability and provides habitat for a wider range of species. Although these measures are expected to help preventing floods and droughts and to promote ecosystem services, they are being implemented on “ad-hoc” designs and it is not clear how they will affect the river biogeomorphology.

This PhD project aims to explore the impact of nature-based solutions on small river systems in the Netherlands. The River Dinkel and the River Vecht will be used as case studies to investigate how recent nature-based interventions have affected the hydro- and morphodynamics of these small rivers. The research will be carried out by a combination of field measurements, using acoustic instrumentation (ADCPs and ADVs), to evaluate the current situation and numerical modelling to investigate the future development of the systems. In addition, this research will develop tools to generalize the knowledge from the case studies and to assess the impact of different nature-based designs. The PhD project is part of the Growthfund NL2120 program, which includes many partners from academia, consultancy, and governmental organizations.

The PhD candidate will be based at the Marine and Fluvial Systems (MFS) group at the Department of Civil Engineering of the Faculty of Engineering Technology of the University of Twente (UT).
