水位面积曲线测绘方法浅析

The principle of the method of mapping the water level area curve

以常家湾水文站实测大断面为例,针对传统断面测绘、水位面积计算及其曲线绘制的不足,提出用全站仪测量、Excel计算和AutoCAD绘图取得水位面积曲线的方法;给出全站仪高程计算公式和Excel计算面积公式,绘制出水位-面积曲线,大断面图。创新一种工作思路,对实现水文工作标准化、高效化具有一定的意义,本方法可供水文测验参考和借鉴。

Taking the measured large section of Changjiawan Hydrological Station as an example,for the traditional section mapping,water level area calculation and the lack of curve drawing,the method of measuring the water level area curve by measuring,Excel calculation and AutoCAD drawing with the whole station instrument is proposed,and the formula of the elevation calculation and Excel calculation formula of the whole station instrument is given,and the water level-area curve and large section map are drawn.It is of great significance to innovate a working idea to realize the standardization and efficiency of hydrological work,and this method can be used for reference and reference in hydrologic test.
