  • Reservoir Sedimentation and Sustainable Management

    Contains 4 Component(s), Includes Credits Includes a Live Web Event on 11/18/2021 at 10:00 AM (MST)

    This webinar is for dam operators, consultants, and decision makers who may not have expertise in sedimentation, but who are interested in sustaining reservoir storage capacity. Management solutions include reducing sediment yields from the upstream watershed, passing inflowing sediments through or around the reservoir, or removing previously deposited sediments from the reservoir. Economic analysis of reservoir sedimentation management will also be discussed.

    Ever wonder what happens when a reservoir reaches the end of its sediment design life? Ever thought about what it would take to replace the current water storage benefits of a reservoir? The problems and solutions to reservoir sedimentation will be described in the USSD webinar on reservoir sedimentation and sustainable management. This webinar is for dam operators, consultants, and decision makers who may not have expertise in sedimentation, but who are interested in sustaining reservoir storage capacity. In 2018, the USSD Board of Directors passed a resolution that “encourages all dam owners to develop long-term reservoir sediment-management plans for the reservoirs that they own or manage by 2030.” (https://www.ussdams.org/wp-content/uploads/2018/03/Sustainable-Reservoir-Sediment-Management-Plan.pdf)

    All rivers naturally transport sediment (clay, silt, sand, and gravel) and reservoirs tend to trap this sediment, reducing water storage capacity. In addition, continued reservoir sedimentation will eventually threaten the reliable operation of dam outlets, reservoir water intakes, boat ramps and marinas. There are no early warning signs of sedimentation problems. The first symptom may be a dam outlet or water intake plugged with woody debris and sediment.

    Sustainable sediment management begins with monitoring, normally through repeat bathymetric surveys of the remaining storage capacity. Management solutions include reducing sediment yields from the upstream watershed, passing inflowing sediments through or around the reservoir, or removing previously deposited sediments from the reservoir. Economic analysis of reservoir sedimentation management needs to compare all costs and benefits associated with each alternative. Although some people assume that ignoring sedimentation is the cheapest option, the cost of sustainable sediment management can be less than the cost of upstream channel aggradation (increased groundwater and flood stage), downstream channel degradation (erosion of habitat, infrastructure, and property), diminishing reservoir storage capacity, eventual dam decommissioning, and the construction of replacement reservoir storage.

     2-hour webinar, including three 30-minute presentations, followed by a 30-minute question and answer session

  • Performance Based Earthquake Engineering and Fragility of Dams

    Contains 4 Component(s), Includes Credits Includes a Live Web Event on 11/16/2021 at 10:00 AM (MST)

    Workshop Objectives -Will go step by step on probabilistic seismic analysis of dams and will provide a clear distinction between different types of analyses, sources of uncertainties, and interpretation of the results. -Provide attendees with the fundamentals needed to expand on the PFMA and perform a sound PBEE on dams. -This workshop is useful for beginners in probabilistic structural and seismic analysis of dams (as the road map will be provided), and those have limited experiences (as the current gaps will be filled out and the future trend will be explained). At the end of this workshop the engineers will be able to develop their own seismic fragility models for dams, and the managers will be able to understand and connect those engineering models with decision-making elements.

    Although the potential failure mode analysis (PFMA) is an standard and well accepted method in Dam Engineering, the complementary one, i.e., performance based earthquake engineering (PBEE) is widely used in building, nuclear, and bridge industries. While these two approaches have some similarities, the PBEE quantifies the results of numerical simulation in a more rational way and ultimately presents results it in the form of seismic fragility curves (SFC). A SFC is a sigmoid type curve in which the horizontal axis present the uncertain variable (e.g., peak ground acceleration or first-mode spectral acceleration), and the vertical one could be probability of exceedance of a particular "limit state" (such as tensile stress or crest displacement). The SFC is one of the final products in PBEE which is very useful for both engineers, managers, and dam owners. It provides a direct connection with loss model elements (e.g., monetary loss, fatalities, and downtime), and is a great asset for risk-based safety assessment of dams.

    Developing SFC requires some knowledge about: (1) finite element model development, (2) different uncertainties sources in a typical case study dam, (3) different probabilistic analyses techniques and their differences, (4) optimal model development as the dam-foundation-water system is computationally expensive, and (5) developing the SFC using the raw data from structural simulations. 

    This workshop will briefly cover all these topics and will provide a rich step by step framework for dam engineers on their journey to develop and interpret the seismic fragility curves. 

    The application of probabilistic methods and fragility functions in Dam engineering seems to be inevitable. Therefore, we expect attendees with medium level of experience in structural engineering, earthquake engineering, dam safety, and even geothectical engineering.

    - Understand the fundamental multidisciplinary knowledge areas involved in instrumentation monitoring - Understand the role of risk in a dam instrument monitoring program: o What are the risks / hazards associated with a site? What should you be monitoring for? o Through the use of risk informed thresholds, how will you know if your data is safe? - Understand best practices when evaluating instrumentation data - Understand the role of automation in a modern dam monitoring program: o Additional considerations, equipment, and expertise needed to install and operate an automated instrumentation system - Be introduced to new emerging instrumentation and monitoring technologies - Practice the above topics in exercises and share knowledge through group discussions - Participate in discussions with instrument suppliers about specific issues of interest.

    This Workshop will include presentations, exercises, and instrumentation equipment displays/demonstrations which all are intended to provide workshop participants with improved insight, understanding, and comfort with respect to instrumentation. 

    The Workshop aims to cover a variety of topics related to dam instrumentation monitoring. Attendees will learn the fundamentals, what questions need to be answered by an instrumentation system, considerations to remember when evaluating the data, how does automation improve monitoring program, and be exposed to emerging technologies.

    Workshop exercises will allow discussion of real-world scenarios. The scenarios will involve both embankment and concrete dams, planning of instrumentation system as well as data evaluation. A significant portion of the instrumentation workshop will be devoted to hands-on exercises design to walk participants through the entire scope of instrumentation from planning to design to evaluating data. 

    Instrumentation equipment suppliers will have displays that will be used to enhance the "foundational" presentations, and the workshop will offer time for one-on-one discussions with equipment suppliers regarding general or special questions, issues, challenges, etc. 

    Fundamentally, the Workshop will seek to maximize the opportunities for educational discussions among the participants, presenters, and instrumentation equipment suppliers about real-world situations, and how they might best be addressed.

    The workshop will provide a general overview for the understanding of the factors that influence the accuracy and reliability of dam instrumentation data. Novice to seasoned professionals will all benefit from the workshop. Engineers, dam owners, geologists, technicians, and government agencies should all attend.

  • Reviewing HEC-RAS 2-D Models: Pretty Colorful Animations are Not Always Accurate

    Contains 4 Component(s), Includes Credits Includes a Live Web Event on 11/03/2021 at 10:00 AM (MDT)

    Workshop Objectives 1. Learn good modeling practices for HEC-RAS 2-D modeling and dam breach analysis 2. Identify commonly overlooked mistakes in HEC-RAS 2-D modeling 3. Obtain a checklist to review HEC-RAS 2-D model 4. View live demonstration of HEC-RAS 2-D capabilities and new tools 5. Learn about upcoming changes in future version of HEC-RAS

    For past five years, the H&H community is delighted to use HEC-RAS 5.0 and its subsequent versions, which are public domain, free, and meticulously tested software from HEC and include fully 2-dimensional (2-D) and combined 1-dimensional (1-D) and 2-D unsteady flow modeling in addition to its traditional 1-D modeling capabilities.  In this period, use of HEC-RAS for 2-D modeling has increased exponentially.  HEC-RAS version 6.0, released in May 2021, has many added capabilities and features over previous versions including faster speeds, variable time step, and pre-processing tools.  This will attract even more users using this software.  There are many advantages of using a 2-D HEC-RAS model, including the ease with which a 2-D model can be set up. Does that mean all 2-D models that run and provide results are justified and correct? That is the most important question when tasked with reviewing a 2-D model. This workshop will discuss good modeling practices and identify common mistakes that are overlooked in creating a 2-D HEC-RAS model.  The workshop will include a live interactive demonstration of HEC-RAS 2-D during which participants will play a reviewer’s role in finding model problems.  This workshop is not intended to teach attendees how to use HEC-RAS 2-D; instead, it will focus on providing information for those who review HEC-RAS 2-D models. The workshop will also cover best practices for conducting dam breach analysis and discuss new pre-processing and advanced modeling features of HEC-RAS version 6.0. All participants will receive a checklist for HEC-RAS 2D model reviews.

    This workshop will be of interest to Engineers, H&H modelers (all levels), government employees (model reviewers), dam owners.

  • Underwater Inspection Technologies and Construction Techniques for Dams

    Contains 3 Component(s), Includes Credits

    This webinar provides overviews of manned diving and successful remote technologies; underwater construction techniques to make structural repairs of concrete structures and mechanical equipment; and will wrap up with 3 relevant case histories.

    The average age of dam in the United States is about 60 years. With passing years, underwater structures in dams face integrity issues. These include:

    1) Cavities/cracks/defects in the dam face. These defects could impact the integrity of the dam and create a dam safety issue.

    2) Leakage / concern of operability of emergency gates and seals

    3) Grooves for lowering gates could be corroded and broken

    4) Cement lining of penstock could be compromised thus leading to water leakage

    5) Over years, silt could have been deposited in the reservoir (and Tail race channel) thus giving the dam owners a deceptive reading of water availability in reservoir

     Engineering assessments of existing dams require inspections of submerged structures such as intake structures, gates, valves, waterways, tail races and stilling basins.  Underwater manual inspections have been typically performed by divers. Though divers have historically carried out underwater inspections, they are hampered by water depth / bottom time, differential of pressure (Delta P) potentials and subjectiveness of observation. Remotely operated vehicles (ROVs) are gaining popularity for inspection of dams: unaffected by depth, able to be put in harm’s way, able to ‘see’ through turbidity. New technologies in underwater robotic inspections are continually being developed and upgraded. The first session of the webinar will focus on presenting manned diving as well as remote technologies that are available and been used successfully for performing a variety of underwater inspections. The second session will be devoted to underwater construction techniques utilized to make structural repairs to concrete structures as well as mechanical equipment.  The third session will present 3 case histories.

  • InSAR – Dam Safety Considerations and Applications

    Contains 3 Component(s), Includes Credits

    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

  • 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
