| Abstract: | In discharge measurement by the velocity-area method, determining positions of velocity and depth-measuring verticals is a prerequisite condition to this measurement. The positioning error for cableway and theodolite methods is derived and analyzed in detail and the methods for reducing positioning error are pointed out. |
