Professor Ian Maddock joined Worcester in 1993 and has teaching and research interests in River Science, Hydromorphology, Hydroecology / Ecohydrology, Ecohydraulics and Aquatic Habitat Measurement, Mapping and Modelling. Ian is the leader of the University’s River Science Research Group

The primary focus of his research is on the methods for measuring, mapping and monitoring the hydromorphology of streams and how this influences habitat hydraulics. Ian also has a research interest in the use of Drones or Unmanned Aerial Vehicles (UAVs) and Terrestrial Laser Scanners (TLS) for ultra-high resolution remote sensing of river morphology and river discharge. He has had a UK Civil Aviation Authority approved Remote Pilot Qualification – small (RPQ-s) and has managed the Institute of Science and the Environment’s Permission for Commercial Operation since 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 and Slovenia.

Ian has international experience, having conducted research and consultancy in Australia, Slovenia, Chile, Ireland 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) and environmental consultancies (e.g. ENTEC UK, CDM Ireland) and has a range of publications in international refereed journals and edited book chapters.

He has supervised numerous PhD students and Research Assistants in hydromorphology and habitat hydraulics, hydroecology, ecohydraulics, bank erosion, and river habitat studies. He is currently part of the EU COST Action 15113 on the Science and Management of Intermittent Rivers and Ephemeral Streams (SMIRES) and the COST Action on the Harmonization of UAS techniques for agricultural and natural ecosystems monitoring (Harmonious: COST Action 16219). He was also member of the European Union Aquatic Habitat modelling group (COST Action 626) Ian was lead editor with three other colleagues on a major research volume on Ecohydraulics published by Wiley-Blackwell in 2013. Details are available here.

His University learning and teaching experience includes being a tutor for BSc Geography, BSc Physical Geography and BSc Environmental Science degrees, enhancing undergraduate skills through the use of real-time telemetry at UW river monitoring sites for flow and water quality monitoring, the use of drones for high resolution topographic surveying and geomorphic change detection, and the development of virtual fieldwork (with Dr Des McDougall).
