RestorationWhat is floodplain restoration?

Floodplain restoration involves reconnecting a river or stream to its natural floodplain, giving rivers more room to safely accommodate flood water. Floodplains spread out and slow down flood water and surface runoff, reducing streamflow by 20%, recharging groundwater, and reducing the flooding risk to riverside and downstream communities. Restored floodplains act as filters for nutrients and other pollutants and reduce the sediment load by decreasing the erosion potential of flood water. Floodplains provide recreational space and habitat for fish and birds. Protecting regularly inundated areas reduces the costs associated with flooding, such as loss of life, structures and crops, as well as the costs to maintain flood control infrastructure.
