This course will present potential failure modes for chute spillways and ways to design these spillways to minimize the potential for failure. 1. Understanding failure modes such as cavitation and hydraulic jacking that can affect chute spillways. 2. How to evaluate potential spillway design and construction details that could lead to failure modes. 3. How to evaluate potential spillway failure mode4. Understanding design details that can hel...

Many dams and levees have embankment drains, structure underdrains, and relief wells to control seepage through and beneath the dam and piezometers to monitor the performance of these features. Dam and levee owners, managers, and maintenance staff may be uncertain about the function of these features and what maintenance is required. This webinar will summarize seepage principles and terminology in layman's terms and describe the purposes and...

During recent years the use of unmanned aerial vehicles (UAVs) or drone technology for the inspection and monitoring of dams and levees has increased. This rate of integration is, in part, due to FAA regulation revisions and the advantages regarding personnel safety, flexibility, speed and volume of data acquisition, and cost. This webinar presents an overview of drones and how this technology can be incorporated into dam safety inspections an...

Oroville Dam is the tallest dam in the United States. On February 7, 2017, a section of the concrete chute slab of the service spillway failed during spillway discharge, and several days later the emergency spillway was activated for the first time in the half-century history of the dam, resulting in rapid and severe erosion of the hillside below the emergency spillway weir, and prompting precautionary evacuation of nearly 190,000 downstream r...

The seminar provides comprehensive instruction in inspection and evaluation techniques for dams. The principles, concepts and procedures taught will be readily adaptable to any organization conducting dam inspections and evaluating their compliance with current design standards. Participants learn about a variety of dam types and their appurtenances, the function of typical dam features, and common dam failure modes and the conditions that can...

The conference program will focus on issues of importance to dam owners, government officials and engineers in the west region with applicability to the greater dam and levee safety community as well.

Together Paul Schweiger and Dean Durkee have offered this seminar 13 times in 12 states and it has been attended by more than 800 students. The seminar provides comprehensive instruction in inspection and evaluation techniques for dams. The principles, concepts and procedures taught will be readily adaptable to any organization conducting dam inspections and evaluating their compliance with current design standards. Participants learn about a...

Join us at Conference Chicago at University Center, June 12-14, for Seepage Through Earthen Dams. This 2.5-day introductory course is designed to be a participatory, interactive workshop, which will cover the basic elements required to understand and evaluate seepage-related issues for earth dams. The first day begins with providing an understanding of why seepage mechanisms in earth dams are important to dam safety. Discussions of basic princ...

Join other dam safety professionals for an array of technical and non-technical presentations. This conference is geared towards dam safety engineers and dam owners/operators in the northeastern states.
