Watch Professor Ian Maddock's video biography
Professor Ian Maddock joined Worcester in 1993 and has teaching and research interests in River Science, Hydromorphology and the use of drones or Uncrewed Aerial Vehicles (UAVs) for high resolution surveys and to assess environmental change.
His University learning and teaching experience includes being a tutor for BSc Geography and the newly created BSc Environmental Management and Sustainability degree, and he led the development of and is course leader for the MRes in River Science. He teaches on a range of courses including generic modules (e.g. Environmental Investigations, Dynamic Earth, Geographical Investigations) and subject specific modules (e.g. River Conservation and Management, River Monitoring and Assessment, The Physical Geography of Mountain Environments, the Mountain Environments Field Course). His teaching is characterised by three key features, i.e. 1) the integration of practical work, especially fieldwork, labwork and computer practicals in module content to encourage student engagement for skills development and to enhance student employability, 2) research-informed teaching, and 3) working with students as academic partners for the development of new engaging and immersive learning and teaching resources. Ian endeavours to make module content relevant to real-word issues and the workplace, experiential (through fieldwork, labwork and the use of virtual reality) and promote deep-learning and student engagement.
Ian has been leading on the development of using drones for environmental monitoring, topographic surveying and geomorphic change detection in the Geography and Environmental Science curricula and has enhanced undergraduate skills through the use of real-time telemetry at UW river monitoring sites for flow and water quality monitoring. He has also collaborated on the development of virtual fieldwork with Dr Des McDougall.
Ian’s primary research roles are postgraduate research supervision in Physical Geography and Environmental Science and carrying out and project managing funded research and consultancy contracts. He supervises numerous PhD students and has a 100% track record for successful completions of his PhD students. He was awarded the University's Excellence in Doctoral Supervision Award in 2021. Ian leads the ‘River Science and Uncrewed Aerial Vehicle Surveys ‘area of distinction’ that forms part of the Sustainable Environments Research Group.
The main focus of his research is on developing methods for i) measuring, mapping and monitoring the hydromorphology of streams and understanding how this influences habitat hydraulics and ii) the use of UAVs for ultra-high resolution remote sensing of river morphology, the measurement of river velocity and river discharge, and to quantify soil erosion for conservation agriculture and Natural Flood Management (NFM).
Ian often works collaboratively with river scientists in multidisciplinary teams, especially with ecologists, biologists and engineers and with stakeholders and community groups to develop sustainable solutions to river management and water resource issues. He has had a UK Civil Aviation Authority approved Remote Pilot Qualification small (RPQ-s) and managed the School of Science and the Environments Permission for Commercial Operation from 2011, including updating his pilot competency with additional ground school training to maintain currency in 2016. Ian has flown the University's drones for research in the UK, Chile, Switzerland and Slovenia.
Ian has developed an externally funded research program that has generated field experience and publication based on work in the UK and internationally, having conducted research and consultancy in Australia, Slovenia, Chile, Ireland, Switzerland and the USA. He has provided research and scientific policy support to government organisations (e.g. Environment Agency), research institutions (e.g. Centre for Ecology and Hydrology), research councils (e.g. NERC), local authorities (e.g. Worcestershire County Council) and environmental consultancies (e.g. ENTEC UK, CDM Ireland) and has a range of publications in international refereed journals and edited book chapters.
