What are natural flood Defences?

At a local scale, this can involve installing ‘leaky dams’ in upland streams, or re-planting hedges on farms to slow water flow. At a larger scale, it can involve reinstating seasonally flooded grassland to store flood water away from high risk areas, or slowing flows by restoring river meanders.

How effective is natural flood management?

Flood mitigation dams can reduce downstream flood levels by temporarily storing and later releasing floodwaters. Most dams are used to supply water to the community, but they can, when purpose built, also provide some flood mitigation for events up to their flood storage capacity.
