Incorporation of the Effects of Future Anthropogenically-Forced Climate Change in Intensity-Duration-Frequency Design Values

Abstract

Numerous scientific assessments have shown that human-induced climate changes are occurring, and more changes are expected as atmosphericcomposition is altered. This work focuses on how these changes affect extreme precipitation rates. In particular, design values are sought for extremeprecipitation rates ranging from sub-daily to multi-day events. These values are typically quantified as extreme precipitation Intensity-Duration-Frequencyvalues and, when plotted, are used by engineers and others for planning, design, and operations as Intensity-Duration-Frequency curves. The mostcomprehensive set of existing Intensity-Duration-Frequency curves developed over the past two decades is based on the assumption of a stationaryclimate. A key ultimate objective of this work is to transform Intensity-Frequency-Duration values into a new set that accounts for a non-stationary climatewith varying degrees of climate change.
