摘要
通过对水位~流量关系拟合曲线的研究,利用计算机对水位~流量关系进行拟合曲线,绘制出水位~流量关系拟合曲线,并且得出水位~流量关系计算公式,计算出相应时段水位对应的流量值。
Through study on stage-discharge relation fitting curve, computer technology is used to draw stagedischarge relation fitting curves. In this article, calculation formula for stage-discharge relation is given out, which can figure out discharge values according to corresponding water levels.
