Join us on April 9, from 12:00 PM - 2:00 PM Eastern for Modeling Tailings Dam Failures with 2-Phase FLow. This webinar will cover the following: Failure modes of a tailing dam. Discussion of recent tailings dam failures. Use of Tailings Dam Tool and regression equations to estimate volume releases. Simulate tailings dam breach including tailings material and water volume using a two-phase flow model. Predict downstream mudflow inundation. Simu...

Join us on March 12, from 12:00 PM - 2:00 PM Eastern for Intrusive Activities in Dams and Levees – Are They Worth the Risk of Creating a Flaw? The U.S. Army Corps of Engineers has updated its regulation ER 1110-1-1807, Drilling and Invasive Activities at Dams and Levees, and related guidance based on what has been observed and learned during the last nine years of reviewing drilling program plans. This webinar will describe the update, w...

Join us on February 13, from 12:00 PM - 2:00 PM Eastern for Triaxial Lab Testing for Earth Dams. The triaxial test is the premier laboratory test to evaluate shear strength conditions for earthen embankment dams. This test is common practice in geotechnical engineering but requires a good understanding of the different laboratory steps and procedures. This webinar will present concepts of the triaxial test as it applies to embankment dams. Dif...

Many dam failures have been averted by dam owners and engineers taking quick and effective action to intervene and stop an active dam failure from progressing. The focus of this webinar is to present the most common failure modes at dams and provide information on actions that can be taken to prevent or delay each failure mode. Case studies will be used to show examples of successful interventions. Actions that could potentially do harm and ma...

Dam engineering is about dams, but is done by and for people. As a result, in order to achieve dam safety, we need to understand not just dams, but also the people (including ourselves) involved in designing, constructing, operating, maintaining, and benefitting from them. Social scientists have been studying people scientifically for more than a century, and we are now at a point historically where the social sciences have generated valuable...

Join us on October 13, from 12:00 pm - 2:00 pm for the Delhi Dam Failure. This webinar will involve the presentation of the Delhi Dam failure case history. Delhi Dam failed on July 24, 2010 during a record storm. The failure was a result of a number of factors all contributing to the ultimate failure. The review of dam failure by a forensic team allowed for a good understanding of the mechanisms that lead to failure. Analysis were performed wh...

Join us on August 11, from 12:00 pm - 2:00 pm Eastern for Low-Level Conduits – What Can Go Wrong, How to Inspect, How to Repair? This course will provide an overview of commonly observed issues associated with the most common type of spillway for relatively small dams (riser and low-level conduit). Importantly, the presentation will summarize methods to evaluate the condition of existing conduits and present common methods to repair and/...

Join us on June 9, from 12:00 pm - 2:00 pm Eastern for The 1979 Machhu Dam Disaster: Social Origins and Social Consequences. In this webinar, Utpal Sandesara and Tom Wooten will discuss their book “No One Had a Tongue to Speak: The Untold Story of One of History’s Deadliest Floods.” The course will cover the social causes and social consequences of the 1979 failure of the Machhu Dam-II in Gujarat, India. The flood wiped out d...

While there have been many notable dam failures throughout the past century, the failure of Teton Dam in 1976 led to significant changes at the Bureau of Reclamation, in the Federal Government, and in the dam engineering industry. This course will provide information about the dam, the failure, ensuing investigations, and the changes that were implemented in the years that followed. Five Learning Objectives of This Course: The failure of Teton...

Five Learning Objectives of This Course: Scour of rock is a dam safety concern that requires meaningful quantification It is possible to predict the scour potential of rock using data normally available for dam design High-resolution remote sensing and monitoring can facilitate improved scour assessment Course attendees should develop an understanding of processes and key drivers/controls for scour of rocks Course attendees should be able to e...
