DOWNLOAD EBOOK →The objective of this good practice note (GPN) on dam safety is to provide additional guidance to World Bank staff on the application of relevant requirements under the environmental and social framework (ESF). This GPN provides guidance on using a risk management approach to the application of the dam safety requirements. The guidance contained in this note is designed to enhance the quality of practice without creating new requirements for the application of the ESF. The GPN provides guidance on compliance requirements, a risk management approach to dam safety, risk analysis tools, quality of information and capacity, application to World Bank operations, and procedural aspects. The GPN pertains to: (a) construction of new dams or dams under construction (DUC) under investment project financing (IPF); (b) rehabilitation of existing dams under IPF; and (c) existing dams or DUC that are not financed under IPF, on which the project relies or may rely.

DOWNLOAD EBOOK →This book addresses current international practices applied for dam safety assessments by looking at a portfolio of dam safety projects in various developing countries (Armenia, Georgia, Tajikistan, Mauritius, Madagascar, Sri Lanka, Myanmar and Vietnam) spread across three continents (Europe, Africa and Asia). Safety assessment involved the review of 134 existing dams and comparison with the best international practices. A large part of dam safety assessment involves understanding of dam hazards, standards applied in the design and maintenance, as well as expectation and social circumstances under which the dams have been designed and constructed in a particular country. For example, standards for design floods, ground investigation, selection of design soil parameters and design earthquakes etc. used are often either non-existent or inadequate, which could lead to an unsafe design. If there are no standards to be applied in dam design and construction, consultants are often under pressure from clients to come up with minimalistic investigation and designs, which, after a few years after dam construction, show signs of deficiencies. Very often countries have no regulations and standards for requirements that should cover the maintenance and operation of dams. The book also describes the Portfolio Risk Assessment of Dams, which can be used as a tool by clients and the funding agencies to identify priority assessment and rehabilitation projects that consider societal and economic losses. It also demonstrates how the implementation of Emergency Preparedness Planning could significantly reduce the number of people at risk. This book aims to help clients, consultants and funding agencies which are engaged in dam safety assessment projects in developing countries to focus on issues that are based on past lessons learnt.

DOWNLOAD EBOOK →Dam safety is central to public protection and economic security. However, the world has an aging portfolio of large dams, with growing downstream populations and rapid urbanization placing dual pressures on these important infrastructures to provide increased services and to do it more safely. To meet the challenge, countries need legal and institutional frameworks that are fit for purpose and can ensure the safety of dams. Such frameworks enable dams to provide water supplies to meet domestic and industrial demands, support power generation, improve food security, and bolster resilience to floods and droughts, helping to build safer communities. Laying the Foundations: A Global Analysis of Regulatory Frameworks for the Safety of Dams and Downstream Communities is a systematic review of dam regimes from a diverse set of 51 countries with varying economic, political, and cultural circumstances. These case studies inform a continuum of legal, institutional, technical, and financial options for sustainable dam safety assurance. The findings from the comparative analysis will inform decisionmakers about the merits of different options for dam safety and help them systematically develop the most effective approaches for the country context. By identifying the essential elements of good practices guided by portfolio characteristics, this tool can help identify gaps in existing legal, institutional, technical, and financial frameworks to enhance the regulatory regime for ensuring the safety of dams and downstream communities.

DOWNLOAD EBOOK →'Regulatory Frameworks for Dam Safety' was conceived and prepared in response to growing concern over the safety of dams. Given the large number of dams around the world, the safe operation of dams has significant social, economic, and environmental relevance. A dam failure can result in extremely adverse impacts, including a large-scale loss of human life. For countries with large stocks of dams, the issue of dam safety is critical. The book examines the dam safety regulatory frameworks of 22 countries. It draws comparisons and highlights similarities among the various systems. Most important, it identifies essential elements, desirable features, and emerging trends for dam safety regulatory frameworks. The authors are leading experts in their fields. Daniel Bradlow is professor and director of the International Legal Studies Program at the Washington College of Law at American University and was a consultant to the World Commission on Dams.

DOWNLOAD EBOOK →While dams have multiple benefits, they also represent a risk to public safety and economic infrastructure. This risk stems from two sources: the likelihood of a dam failure and the damage it would cause. While dam failures are infrequent, age, construction deficiencies, inadequate maintenance, and seismic or weather events contribute to the likelihood. To reduce the risk, regular inspections are necessary to identify deficiencies and then corrective action must be taken. To identify deficiencies that could cause dam failures, the federal government established inspection requirements for the nation's federal dams. Once deficiencies are identified, most agencies finance repairs through their operation and maintenance accounts. Funding mechanisms vary for larger rehabilitation activities. At the Bureau of Reclamation, for example, most larger repairs are conducted with annual appropriations to its dam safety program. At some other agencies, dam rehabilitation must compete with other construction projects for funding. At non-federal dams, safety is generally a state responsibility, though some federal assistance has been provided. Funding through the National Dam Safety Program, which is authorized through FY2006, helps states improve their dam safety programs and train inspectors. In addition, the Federal Energy Regulatory Commission and the Department of Labor, Mine Safety and Health Administration require regular inspections at the non-federal dams within their jurisdiction. Even so, there are concerns that most state dam safety programs have inadequate staff and funds to effectively inspect or monitor all of the dams for which they are responsible. Further, there are concerns that states, local governments, and other non-federal dam owners may not have the financial resources to maintain and rehabilitate their dams. Following the failure of the levee at Lake Pontchartrain in 2005, it is likely that there will be increased scrutiny of flood control infrastructure and the structural stability of high hazard-potential dams. Further, there has been periodic pressure for Congress to pass legislation authorizing federal support for rehabilitation work at non-federal dams. Demand for such assistance is likely to increase, but there is currently no federal policy that describes the conditions under which federal funding is appropriate, nor has Congress established criteria for prioritizing funding among non-federal projects. To help inform discussions on the federal role in dam safety, this report provides background information on the nation's dam safety activities and funding mechanisms. It will not be updated.

The Act of 2002 states that the Director of the Federal Emergency Management Agency (FEMA), in cooperation with the National Dam Safety Review Board (Review Board), shall carry out a program of technical and archival research to develop and support: improved techniques, historical experience, and equipment for rapid and effective dam construction, rehabilitation, and inspection; devices for continued monitoring of the safety of dams; development and maintenance of information resources systems needed to support managing the safety of dams; and initiatives to guide the formulation of effective policy and advance improvements in dam safety engineering, security, and management. With the funding authorized by the Congress, the goal of the Review Board and the Dam Safety Research Work Group (Work Group) is to encourage research in those areas expected to make significant contributions to improving the safety and security of dams throughout the United States. The Work Group (formerly the Research Subcommittee of the Interagency Committee on Dam Safety) met initially in February 1998. To identify and prioritize research needs, the Subcommittee sponsored a workshop on Research Needs in Dam Safety in Washington D.C. in April 1999. Representatives of state and federal agencies, academia, and private industry attended the workshop. Seventeen broad area topics related to the research needs of the dam safety community were identified. To more fully develop the research needs identified, the Research Subcommittee subsequently sponsored a series of nine workshops. Each workshop addressed a broad research topic (listed below) identified in the initial workshop. Experts attending the workshops included international representatives as well as representatives of state, federal, and private organizations within the United States. Impacts of Plants and Animals on Earthen Dams; Risk Assessment for Dams; Spillway Gates; Seepage through Embankment Dams; Embankment Dam Failure Analysis; Hydrologic Issues for Dams; Dam Spillways; Seismic Issues for Dams; Dam Outlet Works. Based on the research workshops, research topics have been proposed and pursued. Several topics have progressed to products of use to the dam safety community, such as technical manuals and guidelines. For future research, it is the goal of the Work Group to expand dam safety research to other institutions and professionals performing research in this field. The proceedings from the research workshops present a comprehensive and detailed discussion and analysis of the research topics addressed by the experts participating in the workshops. The participants at all of the research workshops are to be commended for their diligent and highly professional efforts on behalf of the National Dam Safety Program. The National Dam Safety Program research needs workshop on Hydrologic Issues for Dams was held on November 14-15, 2001, in Davis, California. The Department of Homeland Security, Federal Emergency Management Agency, would like to acknowledge the contributions of the U.S. Army Corps of Engineers, Hydrologic Engineering Center, which was responsible for the development of the technical program, coordination of the workshop, and development of these workshop proceedings. A complete list of workshop facilitators, presenters, and participants is included in the proceedings.
