Kevin ObergKevin has been very involved in hydroacoustics for more than 30 years. He led a team that pioneered the use of hydroacoustic instruments in rivers and estuaries. His work included training in hydroacoustic methods, providing technical support in hydroacoustics, validation of instruments and software, and development of innovative applications of acoustic instruments for rivers, . He served as the National Coordinator for Hydroacoustics in the USGS until his retirement. Kevin has extensive experience in measuring floods and has measured some of the great rivers of the world including the Amazon, the Paraná, and the Mississippi Rivers. He also has expertise in streamgaging practices and methods, streamgage operation, and streamflow records. Kevin continues to work with colleagues and friends in Argentina, Canada, Uruguay, Peru, Brazil, Norway, Sweden, the UK and elsewhere on topics related to hydroacoustics and space-based measurements of rivers.Oberg Hydroacoustics

Nick EverardNick has 35 years’ experience in hydrometry, spending over 30 years working at the Environment Agency in the UK, including leading on river flow measurement technologies and techniques for over 10 years. Nick introduced ADCPs and uncrewed ADCP boats to the EA’s monitoring programmes, and led the development and delivery of training.
In 2020, Nick moved to the research institute UKCEH to dedicate more time to advancing hydrometric techniques, and now works extensively with drone and satellite based techniques.
Nick established and led the Yammer network that predated this forum.
