Reinstate floodplain connection
Many rivers have been disconnected from their floodplain. In addition to its many other functions, the floodplain is a natural water storage that can reduce the energy of flood water when the river breaks its banks, by increasing the roughness of the surface that the water is in contact with and facilitating infiltration into the floodplain soils. When floodplains are engaged with the river, they can provide significant reductions in the extent and severity of flooding and disturbance, such as erosion at a local and system-scale. Options to increase connection and floodplain storage include removing artificial levees and re-engaging wetlands. Activities to increase floodplain storage may be incorporated in both floodplain and river management strategies, particularly those relating to flooding. While the floodplain may be the focus the benefits are realised throughout the river channel.
