An investigation is made into the celerity of reservoir flood wave propagation.
本文对水库洪水波传播的波速进行了研究。
If the flood wave is deformed on its way of propagation, there exists acceleration term or inertia force that equals to internal friction.
波体在传播途中变形，则有加速项或惯性力，内摩阻力等于惯性力。
The flood characteristic of the main stream of Songhua river is that the flood is mainly from Nenjiang river, the flood hydrograph is gently, the time of propagation of flood peak is longer.
松花江干流洪水特征是：洪水主要来自嫩江，洪水过程平缓，洪峰持续时间长。
