flood routing

基本解释

Calculation results show that this model can simulate the characteristics of water flow in a floodplain river and can improve the capacity of flood routing simulating and predicting.
计算结果均表明，本文的一维水动力学模型能较好地模拟漫滩河道的过流特征，并改善了漫滩河道洪水演进的模拟与预测能力。
When dealing with the relationship between tributary and main channel during flood routing, the general method is to add the discharge of tributary to that of main channel of the same instant.
在处理洪水演进过程中支流与干流洪水的相互影响时，以前的模型仅将支流流量迭加到干流同时刻的流量上。

The system is decoupled into two subsystems, namely the upper dam site subsystem and the dam site Hukou subsystem, according to its nature. The flood routing is carried out with hydrology methods.
根据该系统的特点，将模型分解为三峡库区和坝址至湖口两大子系统，采用水文学方法进行洪水演进计算。

洪水演进
For natural water course with multi-sandbank,it's inconvenient to simulate flood routing when adopting 1D or horizontal 2D flow model,because of the multi-branches of river.
对含有多个沙洲的天然河道，由于河道分汊，不便采用一维或平面二维模型计算洪水演进过程。
调洪演算
According to the adjustment schemes of limited water level, the top water levels of each scheme are determined by flood routing, and then the corresponding limited water level is calculated.
根据拟定的汛限水位调整方案,通过调洪演算得出各方案下的最高水位,再利用所建立的模型计算相应的极限风险率。
