本文系从流域的調节特性探討設計洪水过程綫放大方法。根据流量过程綫綜合性的反映流域汇流特性的特点,推求它的积分曲綫(蓄洩关系曲綫,W=KQ~n),并依其研究流域特性与洪水演变的关系。經过例証,得到下列結論: 当洪水峯(Q~′)、量(W)对应增加,在洩放能力强而蓄水能力弱的如山区河流(n<1):(1)峯倍此(K_(Q~′))大于量倍此(K_W);(2)涨水面倍此大于落水面倍比;(3)洪峯偏态前扭,洪峯滞时t_P縮短。而蓄水能力强洩水能力弱的如湖沼草滩河流(n>1)适相反。只有蓄洩能力介于两者之間的河流(n≌1)才是峯、量同倍比,而洪峯偏态也不变。文中并指出:在任何河流,洪水加大,則洪水历时应加长。最后建議了应用这些規律的放大方法。
In this paper, we discuss the method of designing flood process line amplification based on the regulation characteristics of watershed. According to the characteristics of the flow process curve which comprehensively reflects the characteristics of catchment, it deduces its integral curve (storage-discharge relation curve, W = KQ ~ n) and studies the relationship between the characteristics of the catchment and flood evolution. After the demonstration, the following conclusions can be drawn: when the flood peak (Q ~ ’) and the amount (W) increase correspondingly, in mountainous rivers where the discharge capacity is strong and the water storage capacity is weak (n <1) (K_ (Q ~ ’)) is greater than the amount of times this (K_W); (2) the water surface times times greater than the surface water ratio; (3) before the peak skew, peak t_P shortening. The weak water storage capacity of the drainage capacity of lake lakes and grassy rivers (n> 1) the opposite. Only the river (n≌1) between which the capacity of the reservoir is located is the peak and the same amount of times, while the peak deflection is not changed. The article also pointed out: In any river, floods increase, the flood duration should be extended. Finally, the proposed application of these laws of the amplification method.
