针时现有明渠流量测量方法的不足,提出一种规则断面明渠流量的自动测量方法-"流速-水位法".首先基于断面流速分布经验公式,给出"流速-水位法"测量明渠断面流量的基本原理、计算公式及测量步骤;然后应用该法对某实际灌区的两个典型断面进行流量测量,并与流速-面积法的实测结果作对比,两者符合的较好,说明本文所提出的"流速-水位法"是准确可行的.实例应用成果表明,所提出的"流速-水位法"可用于规则断面明渠流量的自动测量.

An automatic discharge measurement method for open channels with regular sections,i.e.,velocity-water level method,was presented in view of the shortcomings of the current discharge measurement methods for open channels.Firstly,basic principle,calculating formula and measurement procedure of the velocity-water level method were presented based on the laws of velocity distribution.Then,discharge measurement of two typical open channel sections of a real irrigation district were conducted by using the velocity-water level method.The discharge measurement results were compared well to the measured results by the velocity-area method.which shows that the velocity-water level method presented herein is accuracy and feasible.The real application results show that the velocity-water level method can be used in the automatic discharge measurement of open channels with reguhr sections.
