River Nar: Felled trees used to slow flow and stop flooding

30 January 2014 Last updated at 15:50 GMT

Eight land owners have joined an experimental project to restore a river in West Norfolk.

Over hundreds of years rivers have been squeezed into straight fast-flowing channels to speed up rainwater drainage from fields, but that has contributed to the flooding of prime agricultural land downstream.

On the River Nar trees have been felled into the channel of the river, forcing it to change direction, meander and eventually lengthen in the hope of reducing the threat of flooding further downstream.
