洪水演进洪水演进flood routinghongshu一yonJIn洪水演进(fl以〕drouting)研究洪水波沿河道(或分洪区、滞洪区)传播演变的计算方法。目的是根据上游干支流出现的洪水过程及区间来水，预报下游某断面的洪峰流量、出现时间、最高水位及洪水过程，为下游洪水预报及防洪提供依据。洪水波传播属河道不恒定流，其演变规律符合圣维南方程组。沿河道的洪水演进分水文学方法与水力学方法两类。水文学方法用河段水量平衡方程和槽蓄方程分别代替圣维南方程组中的连续方程和动量方程11一‘d.d一心I一O-(1)W=f(I，O)(2)式中I，O，W分别为河段人流、出流和槽蓄量;t为时间。联解(”式和(2)式可求得洪水演进方程。水文学方法简单直观，其成果精度取决于实测资料的可靠性与完整性。此类方法很多，比较常用的方法有马斯京根法(M、lskingum Meth记)与经验槽蓄曲线法等。(l)马斯京根法。其基本方程为02=CoIZ+C一11+C:01(3)其中系数Co=CI=0.5山一Kx0 .5山十K(l一工)0 .5山+Kx0.5山+K(l一x)K(l一x)一0.5山0 .5山十K(l一x)式中01，02为出流断面时段初及时段末流量;了l，12为人流断面时段初及时段末流量;山为时段长，K为蓄量常数，具有时间因次;x表示在求槽蓄t时人流t与出流量的相对权重;K，x值可由实测地形和水文资并确定。已知人流过程及起始出流量，可按式(3)求得出流过程。当洪水变化缓慢时，本法成果精度能满足工程设计及洪水预报要求，实际应用较广。(2)经验槽蓄曲线法。根据河段实测人流和出流及槽蓄量资料，建立关系(经验槽蓄曲线)，已知人流过程，经与水量平衡方程联立求解，即可求得出流过程线。水力学方法可分为详算法和简算法.详算法又称水动力学方法，按圣维南方程组(4)(5)式求解。、、少、，产汤任亡d产‘、了‘视丽卜连续方程动量方程就1 JV .V刁V .VZ二二一—X-=二十—X二苏十只;不dog叮g《几〕L“式式中，Q为流量，m“/s;A为过水面积，mZ .q为区间单位长度人流量，m“/(s .m);V为断面平均流速，m/s;h为水深，m;i为比降;C为谢才系数;R为水力半径，m;g为重力加速度;t为时间;S为距离，m。
