DLS-208 07 Concentrated Leak Erosion
Channel: USACE Risk Management Center
Date: 2022-05-12

Course Overview
Through this training course, establish the essential skills for assessing internal erosion potential failure modes in support of dam and levee risk assessments. This course provides pertinent background related to physics and mechanics of the internal erosion processes, summarizes important case histories, and identifies best practices for estimating probabilities of failure. Physics-based analytical models are central to assessing internal erosion potential failure modes, and an in-depth understanding of their application is essential to informing judgment for sound and consistent risk-informed decision-making. This training course includes demonstrations and hands-on practice with the U.S. Army Corps of Engineers (USACE) Risk Management Center (RMC) Internal Erosion Suite of toolboxes.

Learning Objectives
By the end of the training, participants will have the expertise and background needed to participate in facilitated team quantitative risk analyses. In addition, participants will be able to:
• Describe the physics and mechanics associated with internal erosion mechanisms
• Develop an internal erosion event tree and estimate probabilities for each event
• Identify how internal erosion has occurred in the past using relevant case studies
• Use the spreadsheet tools in the RMC Internal Erosion Suite

Module Objectives
Identify the internal erosion process 

Explain situations where concentrated leaks may occur

Assess the likelihood of initiation
