摘要
用流体力学的基本理论,论证了河流洪水的基本特性:洪水漫滩后,主槽过水能力降低;由于主槽过水能力降低,上游来水形成雍水;河流洪水运动的有旋性;河流洪水能量的耗散性。提出联解流体力学的基本方程组进行数值洪水预报。
Using of basis of fluid mechanics, the intrinsic property of the flood was demonstrated： such as discharge decrease in the main channel of river flood flow after flood over the bank, the phenomena of water level raising, river flood flow in rotating sys- tems, river flood flow in dissipating systems. Mathematical forecast of river flood flow using the solution of equations of fluid me- chanics was developed.
