A volunteer flood conservation officer is being sought in the South East to help advise thousands of homes and businesses.
The Environment Agency wants to recruit a volunteer with "extensive knowledge" of conservation along the River Thames.
The warden would be responsible for advising the Thames Regional Flood and Coastal Committee on environmental issues, such as wildlife benefits.
The river was severely affected by flooding in 2007.
The Thames area to be covered by the volunteer stretches from Oxfordshire and Swindon to London and Essex, and from Buckinghamshire and Hertfordshire to Surrey and Hampshire.
Amanda Nobbs, chair of the Thames Regional Flood and Coastal Committee (RFCC), described the Thames area as being "vulnerable to climate change".
The Environment Agency said 20,549 homes benefited from reduced flood risk last year as a result of the work of the Thames RFCC.
Recent examples of the committee's work includes a £11.3m flood defence scheme, in partnership with Woking Borough Council, at Hoe Valley in Woking, Surrey.
