Abstract
This chapter summarizes methods for incorporating risk and climate change into hydrologic design procedures based on the new guidance document from the Federal Highway Administration: Hydraulic Engineering Circular #17 (HEC-17), “Highways in the River Environment—Floodplains, Extreme Events, Risk, and Resilience.” The document includes suggested levels of analysis for risk and vulnerability assessments of riverine transportation infrastructure. The guidance draws on the best actionable engineering and science methods, as well as data found in technical publications and reports, accepted manuals and standards, and federal and state agency reports. HEC-17 encourages the use of confidence limits whether or not climate change, or other sources of potential nonstationarity, is explicitly considered. It introduces a quantitative indicator—the climate change indicator—to assess whether projected climate change might be significant compared with the underlying variability and uncertainty in the historical record.
