This is an interactive seminar focused on the application and benefit of two-dimensional flow capabilities of HEC-RAS, specific to the dam safety industry. The course will maintain a balance between lecture-style presentations on model theory and hands-on workshop sessions for examples of model applications. Topics will include applications and benefits of HEC-RAS 2D modeling; RAS Mapper and terrain preparation; running 2D models including dam...

Join us on May 14, from 12:00 PM - 2:00 PM Eastern for Preventing Fatalities in Confined Spaces at Dams. Most dams have facilities that include permit-required confined spaces. These spaces can include towers, risers, galleries, manholes, vaults, conduits, instrument enclosures, tunnels, adits, drainage systems, etc., that are often unmarked and possess several unique hazards to dam inspectors, operators, and trespassers that are not intuitive...

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...

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/...
