    Model Studies - Foothill Feeder Project Metropolitan Water District Of Southern California Part II. Big Tujunga Gate And Spillway Structure
    (St. Anthony Falls Hydraulic Laboratory, 1968-02) Anderson, Alvin G.; Anderson, David J.
    The Foothill Feeder Project of the Metropolitan Water District of Southern California incorporates a long tunnel that will be part of the system which will supply water to a large area in Southern California. In this system head control devices are needed to regulate the discharge through the tunnels and the appurtenant structures, and for this purpose gated structures open to the atmosphere were chosen. The gate structures, circular in plan with the necessary emergency overflow weirs, were made large enough so that machinery access into the tunnel for maintenance could be incorporated in the structure. The circular plan also provided certain structural advantages. The research described in this report was carried out to study in detail the hydraulic characteristics for a wide variety of flow conditions for one of these structures, the Big Tujunga Gate and Spillway Structure.

    Model Studies-Foothill Feeder Project, Metropolitan Water District of Southern California, Part IV. San Dimas Reservoir Turnout Structure
    (St. Anthony Falls Hydraulic Laboratory, 1968-08) Anderson, Alvin G.; Anderson, David J.
    The Foothill Feeder Project of the Metropolitan Water District of Southern California consists of a large tunnel which incorporates various types of head control structures as well as other appurtenant structures. Each structure was designed to serve a prescribed function at a particular location. Since the functions were rather similar in nature, that is, to provide a differential head through the structure, the designs were of necessity also somewhat similar. This is particularly true of the San Dimas Reservoir Turnout Structure and the Morris Reservoir Turnout Structure. Detailed experiments were carried out with regard to the operation of the Morris Reservoir Turnout Structure so that some rough projections could be made as to the operation of the San Dimas Structure based upon these experimental results. It should be quite clear, however, that a detailed knowledge of the operating characteristics of the San Dimas Reservoir Turnout Structure can only be obtained by a model study an which all of the geometrical details are incorporated into the model and which is operated in accordance with the proposed operating scheme of the prototype.
