2021 Fall Workshop Series

Probabilistic Flood Hazard Analysis - Tues thru Wed, Oct. 26-27, 9:00 am - 1:00 pm MDT, Eligible for 8 PDHs

Risk analysis for dams and levees requires a probabilistic flood hazard analysis (PFHA) to estimate the magnitude and frequency for a range of floods. The resulting flood hazard curve is summarized by plots and tables of peak stage (or flow, volume, depth, duration) versus annual exceedance probability. PFHA requires a different knowledge base and skill set compared to the traditional approach of using a single design flood estimate, such as the Probable Maximum Flood (PMF). The workshop provides an overview of methods and tools used to develop a flood hazard curve for use in a dam or levee risk analysis. The theory and fundamentals behind stochastic event flood models and Monte Carlo simulation are presented. A modeling framework and required inputs are provided for flow based PFHA models. The workshop emphasizes flow based methods. Precipitation based applications using NOAA Atlas 14 will also be presented. Example applications, exercises, and case histories provide students with some hands-on experience.

The target audience includes civil engineers and hydrologists who have education, knowledge, and experience in flood hydrology fundamentals such as performing flood frequency analysis following the Federal Guidelines and performing reservoir routings using standard methods and tools. The typical student should have a minimum of 2-5 years experience in flood hydrology. Students may have limited experience in risk analysis, but a basic understanding of risk analysis concepts is recommended.

Eligible for 8 PDHs
