Earth-Dam Practice in the United States

This paper presents a brief history of earth and rock-fill clams, including a discussion of the types of failure to which such clams have been subject. General features of projects are covered including outlet conduits, spillways, riprap, and the earth embankment itself. Since, in many instances, adequacy of the appurtenant works determines the safety and economy of a project, these features are discussed. Best current practice in design and construction is described with detailed reference to slope stability, slope protection, cutoff and core walls, earthquakes, costs, maintenance, and grouting. Predictions of future advances are set forth, and helpful design criteria are outlined. An extensive Bibliography adds materially to the over-all value.
