About the webinar<\/h3>\r\n\r\n\r\n\r\n

Stream simulation (SS) culvert design integrates fluvial geomorphology, hydrology, civil engineering, and biology to create natural, dynamic stream channels through culverts or bridges at road\u2013stream crossings. While originally developed to facilitate fish and aquatic organism passage, SS can also produce highly flood-resilient designs. Key requirements include: sizing a single-span structure wider than bankfull channel width; developing a natural streambed and banks at an appropriate slope; and checking hydraulic capacity to ensure a headwater-to-depth ratio < 0.8 at the 1% annual exceedance probability flood.<\/p>\r\n\r\n\r\n\r\n

The July 2016 flood in northwest Wisconsin\u2014driven by over 8 inches of rain in roughly 6 hours\u2014caused major damage in the Chequamegon\u2013Nicolet National Forest, including failures at numerous road\u2013stream crossings. During flood recovery, high-water marks and peak flood-flow estimates were obtained at 26 crossing sites. These estimates helped quantify flood severity and differences among watersheds. Seventeen of the 26 sites were designed using SS; 16 survived, even though 13 overtopped.<\/p>\r\n\r\n\r\n\r\n

A case study of these observations was published by the US Forest Service: https:\/\/doi.org\/10.2737\/NRS-GTR-231<\/a>.<\/p>\r\n\r\n\r\n\r\n

Join the authors to discuss flood drivers, factors affecting culvert survival and failure (including SS design and site characteristics), watershed influences on flood response, implications for vulnerability to future flood flows, and how SS culvert\/bridge designs can be further enhanced for flood resilience\u2014along with potential long-term cost benefits.<\/p>\r\n\r\n\r\n
