The Energy & Environment Institute and international partners hosted this three-day theoretical and technical workshop, addressing non-contact surface velocity methods for the determination of river and floodplain flows.
View recorded presentations via the workshop youtube playlist
The event was co-organised by:
University of Hull
University of Sheffield
UK Centre for Ecology and Hydrology
With the support of: :
The International Association for Hydro-Environment Engineering and Research (IAHR)
The UK Fluids Network
The World Meteorological Organization (WMO) HydroHub
Topics covered during the three-day workshop series include:
• Camera based methods • Radar methods • Acoustic methods • Thermal imaging • Drone based methods • Velocimetry using satellite imagery and earth observation • In-channel and floodplain hydrodynamics • Software tools and data processing • Site considerations and site selection • Practicalities and legalities of drone flying • Uncertainty and verification in results • Innovation to improve results and overcome practical limitations
Over 400 global experts and experienced practitioners attended the workshop sessions to to share their knowledge through presentations, training and discussions. The final day focused on innovation, and overcoming limitations with these methods.
It is hoped that the workshop will become an annual event. Please check back on this page for news of future plans.
