Structural Behavior of Dams for Managers
8 PDHs
Bruce Brand’s “Structural Behavior of Dams” is a 3-day course on Dam Engineering. This Manager’s Version is cut down to 1 day. Its purpose is to inform managers who review the work of those who have taken the 3-day intensive course just what Bruce has been teaching them. It is similar to the 3-day course with less math and less discussion of software. Bruce originally developed the course for FERC engineers, but now is offering it to the dam engineering community.

Introduction to Immersion Vibrated Roller Compacted Design Construction
2 PDHs
Immersion vibrated roller-compacted concrete, or IVRCC is a new concept for constructing RCC dams. Simply put, IVRCC is a single RCC mixture that can be consolidated by both immersion vibrators and smooth drum vibrating rollers. This allows a single, durable RCC mixture to be utilized for the dam, exterior dam facing, and interface contacts at foundations and other concrete elements. A single mix and more continuous RCC construction process can improve production and reduce costs. The range of Vebe consistency of this type of RCC is typically from about 8 to 12 seconds, considerably more workable than in early RCC dams. The transition from extremely dry RCC to stiff IVRCC consistency in dams has allowed several improvements in RCC mixtures and IVRCC can simplify dam construction. The improved workability reduces the tendency for segregation and allows for more effective use of air-entraining, water reducing, and retarding admixtures. This webinar will trace the trends in RCC mix consistency allowing IVRCC to be feasible for new dams and in dam safety modifications. Design considerations, mixture proportioning requirements, quality control, and construction means and methods will be discussed. Three North American dams will be highlighted to introduce IVRCC for design and construction.

Infrastructure Resiliency Through Risk Management
USSD invites you to join more than 700 dam and levee professionals in the beautiful city of North Charleston, SC at the Charleston Area Convention Center.
The conference agenda is packed with over 100 technical sessions, two plenary sessions, a Legacy lecture, and six workshops. Of course, while the purpose of the conference is technical knowledge exchange, there will be plenty of time to network with colleagues and industry leaders with two exhibit hall receptions and lunches. The Exhibit Hall, now known as the Marketplace, will be the place to view the latest products and services from exhibitors. Spend time in the Marketplace to win prizes donated by USSD and our exhibiting companies. Plan on staying through Friday to take advantage of Thursday’s workshops, included in your full registration, and Friday’s field tour (additional fee).
Be sure to check out information on the International Symposium on Dam Safety that will be held on Thursday, April 20, 2023 in conjunction with the conference.
Find more detailed conference, symposium & hotel information, plus attendee registration on our conference website.
