Nature based solutions (NBS) refers to the use of natural materials, and natural conditions, along with engineered structures that incorporate natural processes and materials. In the riverine environment, NBS can be used along with traditional, gray countermeasures to reduce the risk of lateral migration of stream channels, stream instability or erosion, and flooding, among other risks to transportation corridors in the riverine environment. Most of these risks are expected to intensify under changing precipitation patterns associated with climate change. The resulting increase in high flows and increased soil moisture exacerbates the risk of flooding and stream instability near transportation infrastructure, and can potentially increase delays and trip length while affecting structural integrity and accelerating deterioration. We discuss the different definitions of NBS and NBS strategies that can be installed in the riverine …
