Note générale : |
This chapter describes the procedures for measuring discharge in large streams by moving - boat technique. During the traverse of a boat across a stream, a sonic sounder records the geometry of the cross section, and a continuously operating current meter senses the combined stream and boat velocities. These data are converted to discharge for the cross section quickly, efficiently, an inexpensively. Measurements obtained by the moving - boat technique compare within 5 percent of measurements obtained by conventional means. A complete facsimile example of computation of a moving - boat measurement is given, and the determination and application of adjustment factors are described. |
