Dr Robert (Bob) Grabowski is an interdisciplinary scientist specialising in the interactions between physical processes, ecological communities and humans within river-floodplain systems.
Bob’s background lies in quantitative aquatic ecology. He received a BSc in Biology (Illinois Wesleyan University) and an MSc in Marine Biology (University of Maine – Orono). His interest in biological-physical interactions, particularly for organisms living within and on the sediment bed, led him to fluvial geomorphology and a PhD investigating fine sediment transport processes in vegetated chalk streams (Queen Mary, University of London). Later, Bob was a Research Fellow on the EU-funded project REFORM (Restoring rivers FOR effective catchment Management), where he helped to develop an open-ended, pan-European framework to assess and monitor river hydromorphology in line with the Water Framework Directive. The REFORM website and wiki are an excellent resource of information on river restoration, hydromorphological assessment, and the ecological effectiveness of restoration (www.reformrivers.eu; wiki.reformrivers.edu). He joined Cranfield as Lecturer in Catchment Science in 2014.
Bob leads a variety of pure and applied research projects in fluvial geomorphology, aquatic ecology, and integrated land and water management. His expertise lies in fine sediment transport, for which he uses a broad range of tools and approaches to quantify erosion from land surfaces, transport fluxes and dynamics through river networks, and ecological impacts in rivers and floodplains, including remote sensing data, field surveys and monitoring, laboratory experiments, and hydrological and hydraulic modelling.
Bob and his research students are working on a range of topics in fluvial geomorphology, aquatic ecology and catchment science. Current and recent projects include:
- Social, economic and environmental trade-offs in managing the land-river-interface (PI, NERC, Towards a Sustainable Earth, 2019 - 2021) - The project is investigating how land and river management can be harnessed to achieve sustainable development goals.
- Improved prediction of cohesive sediment erosion based on inter-particle forces (PI, EPSRC, 2020-2022)
