Book Description
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.

Book Description
Wetlands are a vital part of the landscape and ecology of the United States, providing food and shelter for species ranging from the beautiful wood duck to the tiny fairy shrimp. These areas provide critical habitat for fish and wildlife, protect communities from flooding, and recharge groundwater supplies—yet they continue to be destroyed at an alarming rate. A detailed analysis of wetlands management, Wetland Drainage, Restoration, and Repair is a comprehensive guide to the past, present, and future of wetland recovery in the United States. The book includes a historical overview of wetland destruction and repair over the past two hundred years and also serves as a unique resource for anyone, from novice to engineer, interested in the process of wetland restoration. Author Thomas R. Biebighauser draws from his own vast experience in building and repairing more than 950 wetlands across North America. Included are numerous photographs and case studies that highlight successes of past projects. Detailed, step-by-step instructions guide the reader through the planning and implementation of each restoration action. Biebighauser also provides a number of effective strategies for initiating and improving funding for wetlands programs. Wetland Drainage, Restoration, and Repair is essential reading for all who care about and for these important ecosystems.
