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.

This book was the first broad exposé of the social and environmental damage inflicted by the growth of corporate agriculture in California. Factories in the Field—together with the work of Dorothea Lange, Paul Taylor, and John Steinbeck—dramatizes the misery of the dust bowl migrants hoping to find work in California agriculture. McWilliams starts with the scandals of the Spanish land grant purchases, and continues on to examine the experience of the various ethnic groups that have provided labor for California's agricultural industry—Chinese, Japanese, Mexicans, Filipinos, Armenians—the strikes, and the efforts to organize labor unions
