Comparison and Calibration of Canal Gate Automation Algorithms

Abstract

Several canal gate automation methods and devices were selected for comparison and analysis. Algorithms that simulate gate operation were developed for the P+PR, BIVAL, Littleman, Colvin, Zimbelman, CARDD, and UMA methods. The algorithm for each method was evaluated in newly developed software, which was integrated into an unsteady hydraulic simulation model. Three small and three large canal systems were used to determine appropriate parameter values for each of the different automation methods. Each of the systems included both threeand five-pool versions, allowing comparisons with previously reported results by the developers of some of the methods. An analysis and comparison of the applicability of the respective methods is presented, along with recommendations for determining calibration constants, as determined from experience gained in performing more than 1,000 simulation runs.
