Traditional knowledge about the rule of backwaterlength variation is reasonable, which is a special case of analytic solution to backwaterlength.
有关回水长度变化规律的传统认识有其合理性,它是回水长度解析理论的一种特殊情况。

Criterion for the terminal of backwater may have effect not only on backwaterlength, but also on the rule of backwaterlength′s fluctuation with discharge.
水库回水末端判别标准的精度不仅影响回水长度的大小,在有些情况下甚至影响回水长度随流量变化的规律;
