This study was conducted to identify methods that have been used in the repair and rehabilitation of concrete dams. Information was obtained through literary searches, discussions with project personnel, and visits to project sites. Each case history includes a background of the project, the deficiency that necessitated repair or rehabilitation, and descriptions of materials and methods used in the repair or rehabilitation. When available, the cost of the repair project and the performance of the repair to date have been included. Case histories included in this report cover a range of deficiencies in concrete structures, including cracking, spalling, erosion, leakage, inadequate PMF capacity, expansion resulting from alkali-aggregate reaction, instability, and insufficient storage capacity.

During the life of a dam, changes in safety standards, legislation and land use will inevitably occur, and functional deterioration may also appear. To meet these challenges, these Proceedings from a panel of international experts assess, define and re-evaluate the design criteria for the construction of dams and the many attendant issues in on-going maintenance and management. Authors include international specialists: academics, professionals and those in local government, utilities and suppliers. Practitioners from these same fields will find the book a useful tool in acquiring a comprehensive knowledge of managing and retrofitting dams, so that they can continue to meet society's needs.

As dams age, they are subject to a series of external agents and processes which tend to deteriorate the qualities with which they were originally conceived to stand against these actions. At the same time, it is often necessary to respond to increased safety standards, either in the structural or hydrological fields. Reservoir sedimentation or wat

Based on a survey of inspection reports, 29 percent of the maintenance and repair problems at Corps dams were observed in intake structures and conduits. Repairs to these structures did not perform as desired in better than 40 percent of the reported efforts and with better than 21 percent reported as failed. A number of products whose manufacturer's literature indicated that their products were suited for application in a wet environment such as that found in intake structures and conduits failed. In some instances, the repair technique was at fault. In others, the product failed to perform as indicated. This report documents selected repair efforts to intake structures and conduits and presents them in a case history format that includes a project description and a history of the repair efforts. The project description identifies principle project features and gives a detail description of the deficiency being repaired to include its history and cause (if known). The descriptions of repair efforts are presented chronologically for each project and include a detailed description of the repair products and techniques used and the performance of the repair (if known). The two most common types of concrete deficiencies being repaired were leakage from cracks and joints and cavitation erosion damage to conduit passageways immediately downstream of gates.

As dams age, they are subject to a series of external agents and processes which tend to deteriorate the qualities with which they were originally conceived to stand against these actions. At the same time, it is often necessary to respond to increased safety standards, either in the structural or hydrological fields. Reservoir sedimentation or water quality issues within the reservoir also give raise to problems that must be addressed. Lastly, climatic change in the management of water resources, and the need for sustainability have clearly become new incidence factors with which Dam Owners will have to coexist in the future. Therefore it is obvious that an increase in budget allocation for remedial and conservation measures is required, in order to reach the increasing operation, supply and security measures which are being established. The relevance of this factor is mostly emphasized in developed countries which own an important heritage of aging dams. In this context, Dam Maintenance and Rehabilitation II constitutes a complete review of the state of art in techniques concerning dam retrofitting and conservation. Contributions are presented either in English or Spanish and correspond to a wide range of topics related to dam maintenance, behaviour evaluation and rehabilitation. This shared knowledge and experience will surely be highly relevant for dam academics and professionals at all technical and administrative levels.
