What are 'leaky dams' and how do they protect Gloucestershire?

As autumn gets under way and the rain starts coming down, communities across Gloucestershire are preparing for potential floods.

Rivers are being monitored, sandbags are being stacked up and natural flood defences are being created.

Shropshire Wildlife Trust has been making "leaky dams" to slow the flow of water downstream – this involves placing branches and twigs across small waterways – to try to reduce flooding in Gloucestershire.
