DLS-114 2.5: Precipitation-Frequency & Prior Distributions for Quantiles
Channel: USACE Risk Management Center
Date: 2022-05-20

Course Overview
Explore how U.S. Army Corps of Engineers (USACE) Risk Management Center (RMC) software can
be used to develop accurate and high-quality flood hazard analyses essential for dam and levee risk assessments. Building on a basic working knowledge of flood hazard theory and methodology, this course shows how RMC-BestFit and RMC-RFA software can increase the quality and timely delivery of flood hazard products, such as flow-, volume- and stage-frequency curves, understand how data can impact risk-informed decision-making when managing and mitigating flood hazards, and determine the importance of developing defensible flood hazard curves.

Learning Objectives
By the end of the training, participants will have the expertise needed to perform routine and non-routine flood hazard analysis for a dam or levee risk assessment using RMC software. In addition, participants will be able to:
• Perform and review flood hazard analysis using the RMC BestFit and RMC-RFA software
• Identify data needs for flood hazard analyses commensurate with the purpose, type and level of risk analysis
• Develop flow-, volume- and stage-frequency curves
• Interpret and communicate flood hazard analysis results
• Develop a network of peers for future collaboration

Module Objectives
Summarize a process for precipitation-frequency analysis
Describe prior distributions for quantiles
Demonstrate how to enter quantile priors in RMC-BestFit
