A historical timeline will be presented that describes the significant seepage-related failure case histories and how various technology developed for seepage analyses and evaluations, including potential failure modes. The history of seepage technology begins in the 1800's but accelerates in the early 1900's and through the late 1980's. Each critical milestone in the evolution of seepage technology will be identified along with key published...

This webinar will provide training on using the PMP to generate the PMF, including a walk-through of the rapidly evolving US Army Corps of Engineers HEC-HMS and HEC-RAS modeling processes to transform rain into runoff. The methodology was updated in 2023-2024 based on major software improvements and is cutting-edge. This webinar will include both theory and case study examples. This is Part II of a webinar by Bill Kappel related to the develop...

This webinar aims to provide an introduction to CFD modeling by focusing on the following: History of CFD modeling Fundamentals of CFD modeling Critical components of a CFD model Application of CFD models for dam and levee safety Benefits of CFD modeling How to setup a CFD model - A step-by-step guide Role of the Modeler in CFD modeling Why not CFD modeling? Learning objectives attendees will receive from this webinar: Understand the basics of...

This webinar will introduce the attendees to the thousands of low-head dams in the country by describing their purpose, operation, and non-jurisdictional nature – that is, apart from national, state, and local dam safety programs. Dangerous countercurrents that can form at low-head dams, responsible for approximately 1,000 drownings, will be explained and illustrated. Legal case histories involving drownings will be examined and the best...
