河流中两站间的相应水位关系,是反映其一河段的某些特性的结果。由於它所考虑的因素很单纯,点绘和引用的步骤很简单,所以也逐渐地成为一种水位推求的办法。为了使这种方法能更趋完善,有助於今後的实际工作,特就水情科同志集体学习研究此一问题所得写成本文,并提出来和大家讨论。—、定义及点绘方法在一条没有支流加入,且区间迳流影响不大的河段,水流主要是从河段的上断面流传而经下断面(如图1—1);上图面设有测站甲,下断面设有测站乙,甲站的水位与错後一个传播时间(指甲站到乙站的洪水传播时间)的乙站水位关系,就称之为甲、已两站的相应水位关系。
The corresponding water level relationship between two stations in a river is the result of reflecting certain characteristics of a river section. Because of the simplicity of the factors it takes into account, the steps of plotting and quoting are straightforward and have gradually become a water-level approach. In order to make this method more perfect and contribute to the practical work in the future, we should write a text about the collective study and study of this issue by Comrades of Water Conservancy and put forward a proposal to discuss with you. -, Definition and Point-Painting Method In a section where there is no tributaries added, and the influence of the interval tidal flow is not significant, the water flow is mainly transmitted from the upper section of the river section to the lower section (Figure 1-1) There are stations A, B, under the section has a station B, A station water level and wrong after a propagation time (Nail station to B station flood propagation time) of the relationship between the water level of station B, it is called A, two stations have been The corresponding water level.
