Video: Re-connecting floodplains – a case study

As part of Somerset’s award-winning Hills to Levels project, Lidar data has been collected in order to establish the whereabouts of old floodplains, and reconnect them.

Lidar data (Lidar is short for ‘Light detection and ranging’) allows FWAG SW to map the ground in 3D and assess different possibilities for moving and managing water.

This video, filmed next to the River Isle near Donyatt, shows how the beginning of an old silted-up channel has been dug out to allow huge amounts of floodwater to be stored in a field, as it once used to be.

Somerset Rivers Authority has been one of the main backers of Hills to Levels since 2015, initially using Growth Deal money from the Heart of the SW Local Enterprise Partnership and, more recently, council tax and contributions from Somerset’s Internal Drainage Boards.

The video is the seventh in a series demonstrating natural flood management techniques across Somerset. It features Joanna Uglow of FWAG SW and was filmed and edited by Watershed PR.
