洪水

It is impossible for all bankfull floods to have the function of silting floodplain and scouring the channel. It deems through study that the main channel of the Yellow River will be obviously scoured only when flood discharge reaches to 1.5 times of bankfull discharge.

并非所有的漫滩洪水都具有淤滩刷槽作用，研究认为，对中低含沙洪水，只要当洪水流量达平滩流量的1.5倍以上，黄河主槽才出现明显冲刷。

To study and evaluate the impact of different frequency's floods on social and economic development of the area of Lower weihe River in shaanxi province up the San-men-xia reservoir Employ the method of items of direct loss,namely,to exact all kinds of loss percents of everythings on the earth submersed by the flood by empirics and practical datas ,and ultimately evaluate the flooded loss of some flood standard.

In this dissertation, as for some problems in flood forecast andreservoir regulation, the research had been done based on the special research topic dynamiccontrol on limit water level in flood season using theories of fuzzy optimizing theory,maximum entropy theory, entropy-weighted multi-objective decision making method, geneticalgorithm etc. And the research focused on evaporation calculation, fuzzy description ofcatchraent impoundage, fuzzy similarity calibration method, nolinear watershed concentrationmodel and error distribution maximum entropy model and risk computation of dynamiccontrol reservoir water level in flood season when the flood forecast and precipitation forecastare taken into consideration.

本文从洪水预报和汛限水位动态控制两个研究方向着手，以汛限水位动态控制研究专题的试点水库为工程背景，运用模糊优选理论、极大熵理论、熵权多目标决策法、遗传算法等理论，研究了蒸散发计算和流域蓄水容量的模糊描述、洪水预报模型参数的模糊相似校正方法、流域非线性汇流模型、误差分布的极大熵模型以及考虑洪水预报和降雨预报动态控制水库汛限水位的风险计算方法。

So many drops their plud insurance has this 22 levees in the 3 flood states, have already on top by flood quarters this week, there are concern doesn't more could of flood.

本周，在三个洪水受灾州至少有22个大坝的洪水已到达顶端。估计超过数十个大坝的洪水将溢出。

Elite that there is little they can do to protect or maintain the populace during such a catastrophe,and thus they wish to avoid any such discussions. China's greatest worry comes from rain, thecontinuous deluges that will occur during the days that follow the pole shift. Denuded of forest

中国最大的忧虑是洪水，连续不断的大洪水将会在极移后的那些日子里发生，人口过剩时代以来森林的大量砍伐及围湖造田等原因，导致这些天然的海绵无法发挥其吸水的作用，中国内陆地区将发现自己全部被冲到洪水和肆虐的河水里。

Firstly the paper digitalizes relief map and analysis the "non-source flood" and "source flood",then using self function of ArcMap or ArcView to calculate flood submerged area of source flood and non-source flood area respectively;next,for proving means feasible,the paper takes 2003 flood data of lower reaches of Weihe River as example to contrast or validate.

因此，快速、准确、科学地模拟预测洪水淹没范围以及计算洪水淹没面积，对防洪减灾具有重要意义。20世纪90年代以来，特别是近几年来，在水动力-水文模型基础上，利用GIS强有力的空间分析和可视化功能，模拟显示洪水淹没区，一直是一个研究热点。

The study of the depositional structure of ancient crevasses splays by means of sedimentology and paleomagnetism is important for the floodplain. While the research on ancient trees, peats and pollens caused by paleoflood is useful to paleoflood discrimination.

在洪泛平原区，对古溃口扇采用沉积学、地球物理学方法研究其沉积结构，对确定古洪水事件具有积极意义；通过古洪水所产生的埋藏古树、泥炭及沉积物中花粉的研究也有助于对古洪水事件的识别。

This year's autumn, the original green trees have become bare, and a great flood came, and floods indiscriminately smashed houses, washed away with people, that loggers come to the moment the flood suddenly thought: If I listening to woodpeckers, then there will not be such an outcome, hey ......

这一年的秋天，原本绿色的树林变得光秃秃的了，一场极大的洪水来了，洪水肆意地冲破了房屋，冲走了人，那个伐木工人在洪水来的一刻突然想到：如果我听啄木鸟的话，也不会有这样的结局，哎

The Blanchard River was close to 7 feet above flood stage at Findlay on Wednesday morning, the highest since a 1913 flood, and it was likely to rise another half-foot or more, the National Weather Service said.

周三早上，芬尼镇布莱切特河水已经高出洪水水位接近7英尺，成为了自1913年洪水以来的最高水位。而且，根据国家气象服务提供的信息，洪水还将可能上涨半英尺甚至更多。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.
