Nature-based solutions (NbS) are increasingly a requirement and/or focus of federal natural disaster recovery and mitigation funding programs. They provide valuable tools toward resiliency of the affected communities and watersheds in the face of more frequent and intense weather-related disasters caused by climate change. However, federal guidance on NbS for flood risk mitigation and watershed resiliency in fluvial settings traditionally focuses only on prescriptions external to the stream channels themselves, such as land conservation, wetland restoration, onsite stormwater management, and floodplain reconnection/restoration.
