在该模型中,可考虑到天然来水的洪峰流量、洪水总量和洪水过程线的不确定性。
In this model, the peak discharge of flood, flood total outflow and flood process are to be considered.
洪水总量减少,洪水历时延长,洪峰流量显著降低,洪水过程线表现为涨洪陡、落洪慢的特点;
The total flood volume is reduced, the flood duration is prolonged, the peak flow is decreased dramatically, and the flood hydrograph is characterized by the rapid rise and mitigatory recession;
考虑洪峰流量、洪水总量对洪水频率的共同决定作用,计算机软件中洪水资料频率的判断,采用综合分析法。
Considering the combined action of peak flood and flood volume, flood frequency use analysis by synthesis method in computer software.
目前的降雨总量与往年持平,洪水的危害也不是特别的严重。
So far rainfall has been low compared to recent years, and the damage from flooding has not been particularly severe.
洪水已经淹没了泰国的中部平原地带并继续向首都曼谷蔓延,曼谷地区经济总量占全国的40%。
Floodwaters that had already submerged Thailand’s central plains moved towards Bangkok, the nation’s capital and home to 40% of the country’s economy.
“东太湖”的面积只占整个大太湖总面积的5.6%,而汛期时,其行洪水量却占整个太湖行洪总量的71.9%。
Although thesurface area of the East Taihu Lake constitutes only 5.6% of the total area of LakeTaihu, in flood season its flow amounts to 71.9% of the total flood flow of LakeTaihu.
流域植被度增大,可降低洪水径流总量和输沙量,显著削减洪峰流量,且减沙效益大于减水效益。
The benefit of sediment reduction is greater than that of runoff reduction with increase of vegetation.
