  • 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

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

    Contains 3 Component(s), Includes Credits Includes a Live In-Person Event on 10/07/2021 at 8:00 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.  The newest version of HEC-RAS 5.0.7, released in March 2019, has many added capabilities and features 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 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 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 5.0.7; 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 features of upcoming 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.

  • Performance Based Earthquake Engineering and Fragility of Dams - Wednesday Afternoon

    Contains 3 Component(s), Includes Credits Includes a Live In-Person Event on 10/06/2021 at 1:00 PM (MDT)

    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.

  • Flood Consequence Modeling with HEC-LifeSim

    Contains 4 Component(s), Includes Credits Includes Multiple Live Events. The next is on 10/06/2021 at 1:00 PM (MDT)

    Attendees will gain an overview of approaches to flood consequence estimation with the focus on gaining familiarity with HEC-LifeSim, a software tool for estimating flood damages and life loss.

    Several Federal agencies have made significant efforts over the last decade to understand and quantify the risk of their dam and levee portfolios. The dam and levee safety community is familiar with probable failure mode analysis and estimating the probability of failure, but there is less familiarity with consequence estimation. 

    Risk is estimated through the combination of the probability of an event, the performance of the structure, and the consequences of failure.  Quantifying consequences can be done at various levels of detail, with the HEC-LifeSim model providing a detailed look at flood impacts and evacuation. The model considers warning delays, traffic, vertical evacuation, and vehicle and structural stability.  

    This workshop is appropriate for water resources engineers, economists, early career practitioners. Also other dam safety professionals seeking familiarity at more senior experience levels.

  • Probabilistic Flood Hazard Analysis

    Contains 3 Component(s), Includes Credits Includes a Live In-Person Event on 10/05/2021 at 8:00 AM (MDT)

    Upon completion of the workshop, the student will be able to summarize the theory behind PFHA models, list the required inputs and analyses, run a flow-based PFHA model, portray results, and communicate findings.

    Risk analysis for dams and levees requires a probabilistic flood hazard analysis (PFHA) to estimate the magnitude and frequency for a range of floods. The resulting flood hazard curve is summarized by plots and tables of peak stage (or flow, volume, depth, duration) versus annual exceedance probability. PFHA requires a different knowledge base and skill set compared to the traditional approach of using a single design flood estimate, such as the Probable Maximum Flood (PMF). The workshop provides an overview of methods and tools used to develop a flood hazard curve for use in a dam or levee risk analysis. The theory and fundamentals behind stochastic event flood models and Monte Carlo simulation are presented. A modeling framework and required inputs are provided for flow based PFHA models. The workshop emphasizes flow based methods. Precipitation based applications using NOAA Atlas 14 will also be presented. Example applications, exercises, and case histories provide students with some hands-on experience.

    The target audience includes civil engineers and hydrologists who have education, knowledge, and experience in flood hydrology fundamentals such as performing flood frequency analysis following the Federal Guidelines and performing reservoir routings using standard methods and tools. The typical student should have a minimum of 2-5 years experience in flood hydrology. Students may have limited experience in risk analysis, but a basic understanding of risk analysis concepts is recommended.

  • Leveraging PFMA to Perform SQRA

    Contains 5 Component(s), Includes Credits Includes Multiple Live Events. The next is on 10/05/2021 at 8:00 AM (MDT)

    Part of the 2021 Fall Workshop Series -- This in-person course will take place over three full days and will cover review of the PFMA process, TRG’s, using the PFMA results to perform a SQRA (including additional required input and how to obtain it), estimating consequences including but not limited to life safety, assessing the results, building the dam safety case, and prioritizing risk reduction actions.

    Despite the criticism that Potential Failure Mode Analysis (PFMA) has received following the Oroville Dam spillway incident, it has been viewed as a standard of care for dam safety evaluations in the U.S., and with some possible improvements to be more expansive, is expected to be so into the future.  Many PFMA’s have been performed for state- and federally-regulated dams, and as a result of that investment, considerable knowledge has been obtained about vulnerabilities associated with specific dams.  As the federal dam owners have embraced risk assessment as the next step in ensuring that dam safety risks are properly evaluated and managed, it is expected that private and state dam owners will benefit from following suit.  Indeed, the Federal Energy Regulatory Commission (FERC) has recently adopted Risk Informed Decision Making (RIDM) as part of their engineering guidelines.  The intent of this training is to leverage and improve on the significant investment that has already been made in performing PFMA’s, and use this information to perform semi-quantitative risk assessments (SQRA) for individual dams or dam portfolios.  These assessments can then be used as a screening tool to identify PFM’s and overall risks which are not likely to meet Tolerable Risk Guidelines (TRG) based on life safety, and as a prioritization tool for reducing risk, performing additional investigations or studies, or performing quantitative risk assessments.  A simplified method for categorizing additional consequences such as those incurred at Oroville is also presented in this training.

    Eligible for 20 PDHs

    Target Audience

    The target audience for this training is dam owners and regulators who are familiar with the PFMA process, and are wanting to move these types of evaluations into the risk arena.  This would include FERC licensees and their consultants; private, municipal, and state dam owners; and state and federal dam safety regulators.
