Risk Management for Dam Construction (2017)

Risk Management for Dam Construction was prepared by the USSD Committee on Construction and Rehabilitation.  This White Paper uses and adapts accepted Project Risk Management techniques for new dams and dam rehabilitation projects.  It discusses the formal Risk Management process, identifies risk categories for dam construction, reviews strategies to manage risks, and presents several case studies where risk management strategies were employed.  It was written for engineers, owners, and contractors engaged in the planning, design, and construction of dam-related projects anticipated to cost anywhere from $20 million to over $500 million.

Improving Reliability of Commonly Used Hydraulic Valves (2017)

USSD recognizes that with an aging infrastructure, additional demands are being placed on dam owners to ensure safe and reliable operation of their dams.  In support of this goal, proper equipment selection, regularly scheduled maintenance, and test-operation of equipment are key elements in determining condition and operational capability of valves. Failure to operate valves upon demand can affect the overall dam safety of a project.  The USSD Hydraulics Committee commissioned its Subcommittee on Gates and Valves to develop this technical report as a source of practical experience and information to achieve long-term reliability of valves at dams.

Guidelines for Dam Decommissioning Projects (2015)

The USSD Committee on Dam Decommissioning has prepared these Guidelines to provide dam owners, dam engineers, and other professionals with the information necessary to help guide decision-making when considering dam removal as a project alternative. The Guidelines will help in the development and execution of a successful dam decommissioning project, which would include all necessary activities associated with the removal of a dam and restoration of the river, from project planning through design and implementation.

Modeling Sediment Movement in Reservoirs (2015)

This report, prepared by the USSD Committee on Hydraulics of Dams, Subcommittee on Reservoir Sedimentation, describes application of mathematical models to reservoir sedimentation, including the issues of selecting an appropriate transport function, sediment delivery to reservoirs, deposition patterns, and modeling specific reservoir sediment management strategies.

Guidelines for Construction Cost Estimating for Dam Engineers and Owners (2012)

Guidelines for Construction Cost Estimating for Dam Engineers and Owners was prepared by the USSD Committee on Construction and Rehabilitation. The White Paper provides support for responsible cost estimating for new dams and dam rehabilitation projects. It has been written for engineers and owners engaged in the planning, design and construction of dam-related engineering projects anticipated to cost up to $100 million. This represents the collaborative effort of representatives from federal agencies, public utilities, private engineering companies and construction contractors. Stages of project design and associated estimates, the development of a work breakdown structure, direct and indirect project costs, overhead, contingency, profit, and other owner costs are addressed as they relate to responsible cost estimating. Examples of Work Breakdown Structures for various sized projects are also presented.

Observed Performance of Dams During Earthquakes

The USSD Committee on Earthquakes has published three reports on this topic since 1992. Volume I includes general observations on the performance of embankment and concrete dams, along with 11 case histories and a table with a comprehensive listing of dams affected by earthquakes. Volume II (2000) provides an updated commentary, and contains 12 case histories and an updated table. Volume III (2014), as with the earlier two volumes, includes general observations, an updated table and detailed descriptions of observed performance for 12 selected dams. In addition, a Bibliography on Performance of Dams During Earthquakes was published in 1984.

There are three volumes available for download here:

  1. Volume I, July 1992
  2. Volume II, October 2000
  3. Volume III, February 2014


Materials for Embankment Dams

Is a report prepared by the USSD Committee on Materials for Embankment Dams. The report provides an outline of important points that need to be recognized and understood when selecting material for use in embankment dams.

The Aging of Embankment Dams

Is a White Paper prepared by the USSD Committee on Materials for Embankment Dams. The White Paper is of interest to owners of dams and those responsible for the safety of existing dams. The report notes that there are aging processes, and a project may develop aging characteristics which need to be examined, studied and remedied to preclude a safety issue.

Strength of Materials for Embankment Dams

Is a white paper prepared by the USSD Committee on Materials for Embankment Dams. The paper is intended to be a “living document” that presents the “state of the practice” for determining fill strength parameters for earthfill embankment dams and the static analysis of embankment dams.

The Executive Summary of Planning Processes

The Executive Summary of Planning Processes for the Development of Dams and Reservoirs – Public Involvement and Alternatives Analysis: A Framework for Successful Decision-Making is based on a USSD White Paper that is now available. The White Paper presents a multidisciplinary decision-making process for the development of dams and reservoirs focusing on public involvement and the analysis of alternatives.

USSD White Paper on Dam Safety Risk Assessment: What Is It? Who's Using It and Why? Where Should We Be Going With It? 

The 2003 White Paper’s overall purpose is “To assess the state-of-the-practice in dam safety risk assessment, and to provide commentary on appropriate types of applications and ways to facilitate and strengthen its use.” The White Paper is neither a “how to” guide nor a standard of practice.
