Analysis on the Asynchronous Measurement Method forSediment Discharge and Discharge at Wenquan Water Station Bortala River

在悬移质输沙率与流量异步施测法基本原理分析的基础上,根据河流特性建立了多年综合及相邻流量测次累积面积百分数与累积流量百分数相关曲线法不同的部分流量权重系数借用方案。经实测资料检验输沙率与流量异步施测法的计算误差符合《河流悬移质泥沙测验规范》精度要求,能满足悬移质泥沙测验的生产需求。

It is based on the basic principle of the asynchronous measurement method for sediment discharge and discharge, according to the borrowing precept of different weight coefficient of partial discharge that based on relation curve between the cumulative area percent of neighboring discharge measure in the comprehensive discharge measure of some years and the cumulative discharge percent correspondingly. The calculation error of asynchronous measurement method is correspond with the precision that is criterion for measurement of suspended sediment in open channels by observation. The method satisfy production requirements.
