Hankin, B., Arnott, S., Whiteman, M., Burgess-Gamble, L. and Rose, S. (2017). Working with Natural Processes: Using the evidence base to make the case for Natural Flood Management. Report SC150005. Bristol: Environment Agency.
Part of the Environment Agency’s Working with Natural Processes evidence program. It presents leaky woody dams, floodplain vegetation and wetland creation as flood measures, warns that poorly placed measures can raise flood risk, and treats baseflow support on permeable ground as “an additional benefit” without quantifying it. The wiki cites it to show that the strongest public evidence base for retention structures is built around floods.
