  • Asphalt Core Embankment Dams (ACED)-Why, Where & How

    Contains 3 Component(s), Includes Credits

    Asphalt has been used to impound both liquids because of its longevity, strength, impermeability, and flexibility. This webinar will provide an overview of the use of asphalt in dams and makes the case for considering its use when appropriate.

    Description

    Asphalt has been used in engineering to impound both liquid and solid substances for millennia. The secret to its longevity is its strength, impermeability and flexibility. These qualities make hydraulic asphalt - dense asphalt concrete (DAC) - an ideal material to produce impermeable lining systems.

    Hydraulic asphalt has been vastly refined and improved, making it highly versatile and widely utilized around the world for dams, reservoirs, channels, lining landfill cells and for central core liners for large embankment dams. In this webinar you will learn:

        1.  The use of Dense Asphalt Concrete (DAC) for the provision of impermeable barrier systems for hydraulic structures
        2.  DAC materials, their physical and performance characteristics
        3.  The use of asphalt as an internal impermeable diaphragm to embankment dams - (Hydraulic Asphalt Core Embankment Dams - HACED’s)
        4.  Hydraulic Asphalt Core Embankment Dams

          -  Why would you consider using DAC as core to an embankment dam?
          -  Where (and when), would you consider using asphalt in a HACED?
          -  How do you construct a HACED?

  • InSAR – Dam Safety Considerations and Applications

    Contains 4 Component(s), Includes Credits Includes a Live Web Event on 04/22/2021 at 10:00 AM (MDT)

    Learn how InSAR can be useful for monitoring dam safety.

    InSAR Mosul Dam


    This webinar will be focused on interferometric synthetic aperture radar (InSAR) applications for geotechnical engineers engaged in dam safety. InSAR is a satellite-based, remote sensing technology capable of measuring ground & infrastructure displacement with mm-scale precision. The technology is deployed as an ongoing monitoring tool to help mitigate geotechnical risk across a number of verticals. InSAR is being adopted by geotechnical engineers in mining, oil & gas, transportation, government and urban infrastructure sectors as a means to feasibly identify subtle surface displacements both in the past and present. Such surface displacements provide insights into potential slope instability, internal erosion, landslide induced damage to assets, settlement related failure modes of assets etc. The webinar will introduce the technology methodology, and work into real industry examples/results. Outline:

    The InSAR methodology used on a hydroelectric dam may change depending on the target application. Therefore, in order to maximize the success of a program, users must understand the appropriate risk mitigation in which this technology should be applied, and should be equipped with the knowledge of it’s relative strengths/weaknesses. As such, the following topics will be discussed: 

    1. Introduction to InSAR
    2. SAR Satellite Data (Frequencies, wavelengths, precision, resolution)
    3. InSAR Methodology
    4. Strengths/Limitations
    5. Operational case studies

      Eligible for 2 PDHs

    For all live webinars, you will join the meeting by coming to this product page at the date and time listed and selecting the Contents Tab.  There you will be able to access the live meeting.

  • Low-head Dams: Explained, Purposes, and Inventory

    Contains 3 Component(s), Includes Credits

    Topics Covered • Low head dams – defined, purposes, issues • What can be done – rehab, removal, signage • Our task group work and involvement Learning objective: Learn how to participate in creating a National Inventory of Low-head Dams Target audience: Dam Safety Directors, staff, and those in industry who support public safety efforts

    A low-head dam is a structure that is designed and built such that water passes over the crest continually from bank to bank.  These structures, also known as diversion dams and grade control structures, serve to provide a reliable water surface elevation upstream for diversion purposes or to control streambed incision.  There are thousands of these structures in the U.S. dating from colonial times to the present.  Besides presenting a barrier to upstream aquatic organism passage, conditions on the downstream side of the dam can present serious dangers to recreationists.  Hydraulic jumps form on the downstream side of low-head dams, and if the downstream depth is deep enough, the jump becomes submerged and forms a powerful reverse current called a “hydraulic.”  In these conditions, anyone passing over these innocuous-looking dams becomes trapped with very little chance of survival.  Those involved in attempted rescues also risk their lives.  These issues will be illustrated with examples and basic hydraulic theory.  Potential actions for those responsible for these structures include installation of signage, dam rehabilitation, or dam removal.  Many of these dams are no longer used for their original intent, while others continue to provide essential services.  To increase public awareness of the dangers and issues associated with low-head dams, the work of a national Task Force on the Creation of an Inventory of Low-head Dams will be described.  Opportunities to assist in this work will be explained to webinar participants.  Eligible for 2 PDHs

  • Reclamation Consequences Estimating Methodology (RCEM)

    Contains 3 Component(s), Includes Credits

    This webinar provides the basics of dam failure life loss estimation for risk analysis, as illustrated through the application of the RCEM method.

    Description

    The Bureau of Reclamation (Reclamation) Consequences Estimating Method (RCEM) is an empirically-based method for estimating life loss consequences from dam failure in support of dam safety risk analysis. This RCEM methodology considers the intensity of flooding and warning time to be the most important factors when selecting ranges of fatality rates for a given exposed population. The method is a simplified approach which relies on a data set comprised of dam failure, flash flood, and other flood-related case histories as a basis for fatality rate selection. Consensus results are developed through a team approach to life loss estimation and confidence in life loss estimates are evaluated. RCEM is the primary method currently used by Reclamation to estimate dam failure life loss.

    Objectives

    The attendee will learn the basics of dam failure life loss estimation for risk analysis, as illustrated through the application of the RCEM method.

    The course agenda will cover an introduction to concepts regarding dam failure consequences estimation, discussion of dam failure case histories, interpretation of inundation modeling output data, warning and evacuation, and the estimation of downstream population at risk. The RCEM method will be introduced and discussed in some detail, and an example RCEM analysis will be conducted as a hands-on exercise for participants.
