DLS-104 Module G1: Failure of Radial (Tainter) Gates Under Normal Operational Conditions
Channel: USACE Risk Management Center
Date: 2022-09-12

Course Overview
Learn best practices for estimating dam and levee safety risks considering hazards, system response, and consequences. The basis for this course is the Best Practices in Dam and Levee Safety Risk Analysis Manual, developed jointly by U.S. Army Corps of Engineers (USACE) and Bureau of Reclamation (USBR).

Designed with cross-discipline experience in mind, this course summarizes the governance and guidelines relevant to dam and levee safety risk analysis, provides an overview of probability and statistics, and describes methodologies for estimating and portraying risks, and for building the case for risk estimates.

Learning Objectives
By the end of the training, participants will
be able to:
• Create potential failure mode descriptions and event trees and use them to develop risk estimates
• Describe the hazards that affect dams and levees and estimate hazard occurrence probability
• Identify relevant case histories and foundational research studies
• Apply principles of theory of probability and statistics to quantify, combine and portray risk estimates
• Identify essential elements of life loss consequence estimates
• Build the case for risk estimates
• Explain governance and guidelines of tolerable risk

Module Objectives
Describe trunnion friction failure mode and risk factors
Apply lessons from case histories to forecast potential failure of radial gates
Explain other failure modes that can lead to radial gate damage
