Community-based Natural Flood Management training

If you love your local environment and interested in how the waterways can be improved for wildlife while reducing the risk of flooding, sign up for our accredited 2-day training.

Thames21 are committed to enabling communities to care for and improve their local waterway. As part of our work to trial natural flood management interventions around London we are providing fully funded, accredited training to local residents who are keen to learn about how natural flood management functions and to gain the practical skills and confidence to be River Keepers in their own area.

A leaky dam – one example of natural flood management

This course will be taking place in the London Boroughs of Hillingdon, Enfield, Harrow and Havering between June 2019 and March 2021.

On Day 1 you will learn about different natural flood management methods and what type of locations they are suitable for. You will take part in a site visit with the Thames21 or local authority Natural Flood Management Officer for your area and gain experience in using the ‘Slow Flow Catcher App’ to assess locations and monitor natural flood management installations. 

On Day 2 you will take part in building appropriate natural flood management installations such as woody leaky dams using local materials. You will learn about the process for getting permission from the local authority and Environment Agency to undertake this work and the health and safety considerations of working around watercourses. 

A short assignment accompanies each day of the course in order for you to practice data collection and consider the process for implementing natural flood management in your local area.

By the end of the course you will be able to talk to other people in your community about how natural flood management can be implemented in the local area and take part in monitor its effectiveness at a local scale.
