汛期庫區線路災害的原因進行了分析,並探討了利用數量化理論對路基防護工程抗洪能力進行預測的意義;第五,提出從風險的角度對交通線路的防災減災進行管理,對風險估計的相關問題進行了論述,並探討了交通線路水害危險區段的劃分問題。
Dynamic control of the limit water level belongs to non - structural measures of reservoir operation. with the analysis of the cause and rule of flood in the catchments and taking advantage of hydrology and metrology information, the operable method can be obtained which not only satisfies the flood prevention but also takes full advantage of flood resources, and the upper and lower limits of the limit water level are determined with serial hydrology calculation. then, the rule of using the upper and lower limits is put forward to reach a beneficial flood operation with small risk

The persistent downpour in chifeng since the start of the rainy season has caused a severe flood disaster rarely seen in history. the heavy casualties and damage to personal possessions and local farming include 3. 85 million acres of farmland submerged, over 70, 000 houses destroyed, and 1. 62 million people affected with more than 60, 000 homeless
今年入
汛以來,我市由於連降大暴
雨,遭受了歷史罕見的特大洪澇災害,給人民群眾生命財產和農牧業生產造成嚴重損失,致使385萬畝農作物被沖淹, 162萬人受災,倒塌民房7萬多間, 6萬多人無家可歸。
Also, it is only relatively recently that models have been developed with the required resolution to sufficiently capture the storms and weather patterns associated with the autumn 2000 floods
這個模型是最近製作出來的,它能顯現造成2000年秋

We focus particularly on the united kingdom autumn 2000 floods because, aside from causing widespread damage, they occurred during the wettest autumn since records began in 1766
我們特別聚焦在英國2000年秋
汛,不只是因為它所造成的巨大災害,更因為那是自1766年有紀錄以來
雨量最多的秋天。
A reliability evaluation model which based on the reliability theory and method is also bring forward to prove that the rainfall alarm system is a kind of high reliable alarm system. in the second part, a new kind of decision technique : extension decision technique is applied to the decision for the debris flow disaster mitigation planning. a kind of matter - oriented method, which is called extenic mode, is set up in this paper to design, compare and optimize the disaster mitigation planning
