Development of Test Procedures for Unbalanced Head Operation of Slide Gates

by K. Warren Frizell, Bureau of Reclamation, Denver, United States,



Document Type: Proceeding Paper

Part of: Management of Irrigation and Drainage Systems: Integrated Perspectives

Abstract:

This paper will discuss the steps taken by the Bureau of Reclamation to develop a standardized procedure for testing unbalanced head operation of high-pressure slide gates for outlet works at dams. Largely driven by a Safety of Dams requirement, the test procedures evolved from an extensive review of literature, a hydraulic model study, and two field tests of prototype installations. The test procedures, now instituted, are simple to carry out and are part of regularly scheduled inspections. There is currently a program to extend the test procedures to include different types of gates, such as fixed-wheel and ring-followers.
