River barriers made up of natural materials like trees, branches, logs and leaves can reduce flooding in at-risk communities by storing water upstream, new research has found. The study, led by scientists from Cardiff University and the University of Worcester, assessed the impact of leaky barriers at a natural flood management site on a small Shropshire river over a period of two years. Human-made leaky barriers, which are designed to imitate beaver dams, work in units of 50-100, deliberately raising water levels upstream to slow down river flow through storage and diversion, providing ecological benefits to the river corridor and on nearby farmland.
