flood routing

基本解釋

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.
計算結果均表明，本文的一維水動力學模型能較好地模擬漫灘河道的過流特征，并改善了漫灘河道洪水演進的模擬與預測能力。
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.
在處理洪水演進過程中支流與干流洪水的相互影響時，以前的模型僅將支流流量迭加到干流同時刻的流量上。

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.
根據(jù)該系統(tǒng)的特點，將模型分解為三峽庫區(qū)和壩址至湖口兩大子系統(tǒng)，采用水文學方法進行洪水演進計算。

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.
對含有多個沙洲的天然河道，由于河道分汊，不便采用一維或平面二維模型計算洪水演進過程。
調洪演算
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.
根據(jù)擬定的汛限水位調整方案,通過調洪演算得出各方案下的最高水位,再利用所建立的模型計算相應的極限風險率。
