Abstract:Natural and Nature-Based Features (NNBF) have been used for decades to support a variety of objectives in coastal and riverine systems. Some types of NNBF, such as river restoration, use of bio-engineering, wetlands and beach and dune projects, have been a longstanding part of flood risk reduction strategies in Europe, the United States and elsewhere. However, stimulated by the outcomes of recent major storm events, there has been a growing interest in developing a more technically sound engineering approach to support the ‘mainstreaming’ of all types of NNBF into more comprehensive and sustainable flood defense systems (in conjunction with conventional flood defense systems). The U.S. Army Corps of Engineers is leading a collaborative project to develop international guidelines to inform the planning, design, construction, and operation or NNBF projects. Participants in the international team come from several countries and organizations including the United Kingdom and the Netherlands and include representatives from government, academia, and the private sector. This paper will describe the emerging issues and likely content of the guidelines including aspects such as guiding principles, design rules for more novel forms of NNBF, spatial upscaling of flow-slowing measures across catchments and adaptive management of NNBF measures.
