The current of the Niagara Falls rushs down cliff to come downstream and new confluent later, continue to roll in gorge buckjump, the with prep above cataract velocity of flow on the reach that in inadequacy 2 kilometers grow is horary the fall that 35.4 kilometers drop to swing and issue 15.8 meters, deduce a world to go up the maddest the the wild, most horrible, most dangerous eddy race, rush again deep the eddy pool of 38, next dragon of a flood dragon turns over, the elder brother that passes east bank Canada this, the Liweisidu of right bank United States, had rushed " devil hole race ", along final " Liweisidu affluent gorge " by enter eastwards on the west install rude lake.

尼亚加拉瀑布的水流冲下悬崖至下游重新汇合之后，在峡谷里继续翻滚腾跃，在不足2公里长的河段上以高于大瀑布的流速每小时35.4公里跌荡而下15.8米的落差，演绎出世界上最狂野。最恐怖。最危险的漩涡急流，又冲进深38的漩涡潭，然后一个蛟龙翻身，经过左岸加拿大的昆斯顿。右岸美国的利维斯顿，冲过"魔鬼洞急流"，沿着最后的"利维斯顿支流峡谷"由西向东进入安大略湖。

The suggestions employed on different river segments included buffer strips, wetland creation and restoration, habitat diversity creation and near-nature engineering, separately could alleviate human disturbances and canalization effects, link broken river corridor, and improve habitat quality and biodiversity.

此外，鉴於B河段河川渠道化日益加深，导致河流廊道潜在栖地消失与河廊联系中断的情形，建议以近自然工法护岸及护堤的规划加以改善。

According to the conflux flow zone in the previous modeling, we divided the upper section of Suzhou creek into three sections.

根据前面所模拟的集流区域，对苏州河上游段进行河网概化，通过GIRD软件建立网格与河段的对应-响应关系。

Meanwhile, a lot of contaminant has been discharged into the river, resulting in pollution in different parts of the river.

同时，大量的污染物排放到河中，造成不同河段的污染。

Eastern Himalaya Syntaxis is an important area in studying climatic-tectonic reciprocity. In this paper, single-crystal-high-precision laser ~(40)Ar/~(39)Ar method was used to build the thermal evolutional history of Eastern Himalaya Syntaxis by tests on river sediments on the lower reach of Yalung-Tsangpo River. The contrast of age statistical results against the figure showing the changes in rate and angle of convergence during India plate has been colliding against Eurasian plate since late Mesozoic and the diagram consisting of global deep-seaδ18O andδ13C records is done, for the purpose of revealing climatic and tectonic information on rock cooling and referring the relationship between thermal evolutional history and climate and tectonics.

东喜马拉雅构造结是气候与构造相互作用的典型地区，本文尝试使用单颗粒高精度单次全熔~(40)Ar/~(39)Ar法对采自雅鲁藏布江大峡谷下游墨脱县城以南约50 km处地东河段的细粒现代河沙进行年代学测试，建立东喜马拉雅构造结的热史演化序列，并通过与代表全球气候变化的18O、13C浓度变化曲线和印度大陆向北运动的速度、角度变化曲线的对比，揭示气候、构造因素与东喜马拉雅构造结热史演化的耦合，推定热史演化与气候、构造过程的关系。

In order to analyze the influence on flood control by Chenhu super bridge in Hanjiang River , a two2dimensional math2ematical model of water flow under non2orthogonal curvilinear coordinates is established , and then , the model is applied to Han2jiang River.

为了分析沉湖特大桥对汉江沉湖河段的防洪影响情况，建立了非正交曲线坐标下平面二维水流数学模型，并应用该模型对汉江沉湖特大桥修建前后的水流运动情况进行了模拟。

At the confluence zone, due to the jacking of current from main stream and tributary stream, the mixing and turbulence of current is so strong and the loss of energy is so large that the balance of water and sediment is broken which could causes sediment particle and coarse grain to deposit and forms shallow shoal at river mouth or eyot.

天然河流中存在着大量的干、支流交汇的河段，在干支流相汇处，由于干、支流两股水流相互顶托，交汇区内水流紊动掺混作用强烈，能量损失很大，干、支河流原有的水沙平衡状态被打破，可能导致泥沙颗粒、尤其是粗颗粒卵石在汇合口处大量淤积，形成河口浅滩或江心滩。
