2015 Annual Meeting and Conference
Index of 2015 Conference Information
The 2015 USSD Conference theme is Managing Risk and Uncertainty — Ensuring a Sustainable Future for Dams, Levees and Reservoirs. With growth in population and development, many older dams and levees that were constructed to protect agricultural interests are now protecting people and personal property, and are being called upon to provide other benefits such as power generation, recreation and water supply. As a result, the risk associated with many of these structures has increased, bringing new costly challenges for owners to retrofit or modify existing dams and levees in response to the expanded role these structures now play.
Operation of dams and levees involves numerous uncertainties about potential extreme loading conditions, the consequences of failure, the condition of the structures themselves, the effectiveness of established operation and maintenance procedures, and human behavior. Safe operation of these facilities must take into consideration all of these uncertainties and simply meeting established engineering criteria does not necessarily mean that a structure will continue to perform safely. In addition, design and construction of new dams and levees or modifications to existing structures involves uncertainties, particularly with respect to the geological materials upon which the structures are constructed. Design and planning for new construction must take into account these uncertainties and how to equitably share the risk of unforeseen conditions.
Recent failures of coal ash storage reservoirs have highlighted the risks associated with waste impoundments, many of which are classified as low hazard relative to the potential for life loss. Safety of these structures has not always been at the forefront of awareness within the industries they serve, with the unfortunate result being that some do not receive the same level of regular inspection and maintenance as dams constructed for water supply, flood control and power generation. Although many of these impoundments do not pose a significant risk to human life, the economic and environmental consequences of failure can be extremely high.
The theme for this 35th Annual Conference highlights that, while dams and levees are critical components of the nation's infrastructure, there are always risks and uncertainties associated with ownership and operation of these facilities. Recognizing and effectively managing these risks and uncertainties is critical to ensuring that these structures will continue to provide the societal benefits that we depend on without posing an unacceptable hazard to life, property or the environment.
The Opening Plenary Session on Tuesday morning will include several presentations addressing contemporary topics of interest to dam professionals.
Five Concurrent Technical Sessions on Tuesday afternoon and Wednesday, and a Poster Session Tuesday evening, will feature the presentation of more than 100 technical papers.
On Thursday, three full-day workshops and two half-day workshops will take place. An afternoon field trip will take participants to nearby projects of the Corps of Engineers.
Elena Sossenkina, HDR, will discuss Lessons in Risk Policy Implementation in a Tuesday lunch presentation. USSD 2014 Scholarship recipient Beena Ajmera, Virginia Tech, will provide an update of her research during the Wednesday lunch.
Charles Yoe, Notre Dame of Maryland University Professor and expert on risk analysis, will be the Wednesday dinner speaker. USSD Awards will be presented, including the Outstanding Paper Awards, the President’s Award, and awards for Excellence in the Constructed Project and Lifetime Achievement. The winners of the 2015 USSD Scholarships will also be announced.
A Planning Committee, chaired by Alex Grenoble with assistance from various technical committees, will organize the Technical Program.

Risk Assessment Tools Applied to Coal Tailings Dams and Ash Impoundments
8:00 a.m. - 5:00 p.m.
Organized by the USSD Committee on Tailings Dams
Moderators — José J. L. Clemente, Bechtel Corporation; and Robert E. Snow, D'Appolonia Engineering
Mine operators and power plant owners have used a variety of methods to assess and rank the risk associated with operating impoundments for tailings and combustion ash. Company management frequently employ tools ranging from audits to risk screenings, performed within their regulatory compliance, environmental, dam safety or risk management departments, to assess potential exposure to release from impoundments as well as environmental impact. Are the risks adequately understood, and the pathways for potential release of tailings or combustion ash sufficiently recognized to support risk assessment? Are procedures for screening and analyzing risk capable of providing guidance in risk management programs? As impoundments are closed either because of service life exhaustion or regulatory decree, can risk assessment continue to be of service?
This Workshop will raise these issues with input from regulatory agency representatives commenting on the types of impoundment risk being encountered across the mining and power industry, owners who assess risk of their impoundments, researchers who characterize the behavior of the materials encountered, and practicing engineers working to maintain or close these structures.
Paths to Success — Environmental Permitting and Public Acceptance for Dam Projects
8:00 a.m. - 5:00 p.m.
Organized by the USSD Committee on nvironment and Sustainability
Moderators — Blaine Dwyer, HDR; and Denise Bunte-Bisnette, Santee Cooper
Throughout the U.S., public agencies and utilities are endeavoring to develop additional water storage as well as better use existing water storage to improve water supply reliability, enhance supply diversification and meet future demands. These processes are bringing forth important new strategies for addressing complex federal, state and local regulatory requirements, environmental needs, and diverse stakeholder and public interests. Owners are facing daunting challenges meeting the requirements of the laws and policies administered by resource and regulatory agencies that often result in lengthy and costly planning and permitting processes. Using examples from across the country, the speakers and panelists will compare and contrast key elements for successful project development including strategic engagement of stakeholders and the general public including impact avoidance and minimization, up-front mitigation implementation, adaptive management approaches, and alternative dispute resolution mechanisms to demonstrate how careful planning supports successful permitting.
Dams on Karstic Foundations
8:00 a.m. - 5:00 p.m.
Organized by the USSD Committee on Foundations
Moderator — Troy O’Neal, Corps of Engineers
Numerous dams in the U.S. have been constructed on sites underlain by bedrock prone to varying degrees of solutioning. The solutioning process is normally more pronounced in areas with increased water flow such as along joints and bedding planes. Initially, insoluble material in the form of residual soil remains. Over time the soft soil is eroded, and a network of open and soil filled voids are left in the rock. The term “karst” is typically used to characterize rock that is known to have solution features.
This Workshop will explain how karst is formed, (both in carbonate and evaporite rocks) and where it is found in the U.S. Attendees will be given an overview of poor performance of dams founded on karstic rock, investigative techniques and alternatives measures for these foundation conditions. Additionally, several case histories will be presented and will be followed by a panel discussion.
Current Uses of Roller-Compacted Concrete in Dams
8:00 a.m. - 12:00 noon
Organized by the USSD Committee on Concrete Dams
Moderator — Michael F. Rogers, MWH
The USSD Committee on Concrete Dams is currently engaged in a collaborative effort with ICOLD to publish an update to ICOLD Bulletin 126 — Roller Compacted Concrete for Dams. USSD will be leading the technical updates to three chapters in the RCC Bulletin: Construction; Performance; and Appurtenant Uses. This Workshop will present a general discussion of Bulletin 126 as well as the proposed updates. The Committee is soliciting USSD members and others with interest and experience in RCC to attend this Workshop and discuss the proposed updates. It is hoped that the Workshop leaders and participants will identify key aspects of these RCC design features that could be included in the updated Bulletin. The current version of Bulletin 126 can be downloaded from the ICOLD website.
Underwater Investigation and Construction
1:00 p.m - 5:00 p.m.
Organized by the USSD Committee on Construction and Rehabilitation
Moderator — Frank Immel, Global Diving & Salvage, Inc.
The purpose of this Workshop is to inform and educate the participants about what can and cannot be done underwater. The idea for this Workshop developed from a conversation about the kinds of work the commercial diving/marine construction community is doing. Members of the engineering community are often surprised to learn that most work that can be performed on the surface can also be performed underwater. It may cost a bit more and take a bit longer, but it can be done. A relatively recent development is the ability to “see” underwater using remote sensing technology to collect and present detailed information about an existing structure.
This Workshop will use presentations and case studies to discuss:
Thursday Field Tour, 1:00 - 5:00 p.m.
Following lunch in the Hyatt Regency Hotel, the Thursday tour will provide a visit to the Corps of Engineers’s McAlpine Lock and Dam and Taylorsville Lake Dam.
Located in the historic Portland neighborhood of Louisville, McAlpine Locks and Dam is a short drive from the Hotel. The original lock and dam was completed in 1830 as part of a 1.9-milelong canal system that was constructed to allow navigation past a falls on the Ohio River. The lock was constructed in 3 flights with a total lift of 26 feet. A hydroelectric powerhouse was added in the late 1920s when the locks were expanded. In 1960, the lock and dam was named for the only civilian to hold the position of Louisville District Engineer, W. H. McAlpine, and was in need of a major renovation. A second expansion project, completed in 2009, resulted in the project on the tour. The current configuration includes twin 1,200-foot-long locks that provide the capacity to accommodate current barge traffic along this section of the river with additional capacity to accommodate projected traffic increases. The 1990 expansion also included replacement of the existing swing and bascule bridges with a two-lane, high fixed span concrete bridge to provide access to Shippingport Island and the Louisville Gas and Electric hydroelectric generating station.
After visiting the McAlpine Locks and Dam, tour will go to Taylorsville Lake Dam, located approximately 45 minutes from downtown Louisville. The dam is one of twenty flood protection projects under the jurisdiction of the Louisville District. Constructed between 1974 and 1983.
Taylorsville Lake Dam is an earth and rockfill embankment with a crest length of 1,280 feet and a height of 162 feet. Taylorsville Lake has a surface area of more than 3,050 acres and provides outdoor recreation opportunities, fish and wildlife enhancement and quality water storage in addition to its primary function as a flood control reservoir.
Friday Field Tour, 7:30 a.m. - 6:00 p.m.
The Friday field tour will go to the Corps of Engineers’ Cannelton Locks and Dam and the adjacent American Municipal Power (AMP) Cannelton Hydroelectric Powerhouse.
The Cannelton Locks and Dam is located on the Ohio River, approximately three miles upstream of Cannelton, Indiana. The current project was constructed as a replacement for three smaller facilities known as Locks and Dam 43, 44 and 45. Construction of the current locks began in July 1963 and was completed in April 1967. The dam was constructed between 1965 and 1974. The Main Lock is 110 feet wide by 1,200 feet long and the Auxiliary Lock is 110 feet wide by 600 feet long. The dam is a concrete gravity weir with a crest length of 1,412 feet and is equipped with 12 tainter gates, each of which is 42 feet high by 100 feet wide.
The Cannelton Hydroelectric Project is the first of AMP’s four run-of-river hydroelectric projects currently under construction. A guided tour of the powerhouse, which is nearing completion, will be provided by AMP and the design engineer MWH. The powerhouse is equipped with three horizontal bulb turbines with a capacity of 28 MW each and is capable of generating a total of 84 MW at a gross head of 25 feet.
Lunch will be provided by the tour hosts, the Corps of Engineers, AMP and MWH.
Guests will have an opportunity to meet and mingle during a coffee reception on Tuesday morning. A representative from the Louisville Convention and Visitors Bureau will introduce guests to the city and its many attractions. This event will be an opportunity for guests to join others in activities or tours to be arranged on your own. Information on possible tours will be available at the Meet and Mingle event.
Guests will also enjoy the following Conference activities:
The Guest Registration Fee is $325.
