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...

The safe operation of dams and appurtenant structures is paramount to the communities they serve. Instrumentation is an important tool of a comprehensive dam safety and performance monitoring program that can detect changes that might otherwise be missed by visual surveillance. The objectives of this course are to provide the participants with a general understanding of dam performance monitoring and its purpose; instrumentation and measuremen...

This webinar will include a discussion of common challenges with the design review process for dam safety projects and present strategies to improve the efficiency and effectiveness of the process with a focus on early and regular engagement of the owner, regulator, and designer. Learning Objectives of This Webinar: Pitfalls to avoid during the design review process. Strategies to improve the efficiency of the design review process. Independen...

This webinar will review field inspection of concrete structures for dams, water conveyances, and levees. Specific topics to be covered will include foundation preparation, reinforcing steel inspection, embedded items, formwork, concrete joints, waterstop installation, and concrete mixes and placement. Five learning objectives of this webinar: Pre-construction preparation that should be completed prior to the start of construction of a concret...

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/...
