Ice will not only influence shipping, transportation, hydraulic power, water and sewage, but also lead to ice flood and cause huge losses when ice blocks the river course severely.

河流中的冰凌不仅直接影响到冬季的航运、交通、引水发电、给排水等水利工程建设事业，而且当冰凌严重阻塞河道时，往往会导致凌洪泛滥成灾，给人民生命财产带来重大损失。

These machineries which develops for the adaptation different river course environment, although the model varies, but Wan Bian to its, its principle of work is not same, that is elects through the magnetic separation way the river sand in magnetic iron.

Un-equilibrium transport of sediment is the key of bed evolution of rivers and estuaries. The factors in sediment transport are very complex, for flows with sediments in nature are often turbulent flows.

泥沙输运的不平衡是河道、河口河床演变的物质基础，而影响泥沙输运的动力因素较为复杂，尤其是自然界存在的挟沙水流往往是紊流。

This paper introduce the reform of river-crossing simply brdge by using ultrathin lifting jack ,this mode avoided the foundation treatment under the bridge,reduced the influence of the river and the adjacent environment.

介绍了跨河简支梁桥采用超薄千斤顶少支架整体抬升的工艺，从而避免了桥下河底的地基处理，降低了对河道及周边环境的影响，并结合抬升施工对过河管线进行了相应改造，改善了桥梁景观效果。

On the basis of the researching of facies、 petrology、 cathodoluminescence analysis, this paper concludes that the terrigenous clastics in Pingyipu Formation were mostly originated from Motianling palaeo-peninsula lied to its north, and sands in distributary channels、 braidedriver in estuaries、 deltas and in littoral zone in hybrids could be derived from Middle-Sichuan Palaeoland with Peng-Guan Highland.

对早中泥盆世浑水陆源碎屑沉积及混合沉积的沉积相、岩石学、阴极发光等研究分析，作者推测，该区陆源碎屑主要来自北边的摩天岭古半岛，而分流河道、辫状河充填及混积滨岸砂则可能以川中古陆和彭灌高地为主要源区。这一点与过去通常认为的主要来自彭灌岛和轿子顶古岛差别较大。

Major changes in a river course result in both lateral shifts of the old meander belt and in the development of new belts.

河道中大的变动，造成老河曲带的侧向迁移和新河曲带的产生。

Gradually the river grows wider,the banks recede,the waters flow more quietly,and in the end without any visible break,they become mered in the sea,and painlessly lose their indivedual being.

渐渐地，河道变宽了，河岸拓展了，河水流得更平缓了。最后，河水一泻千里汇入了大海里，毫无痛苦地失去了自己。

Frame for the distributary channel sandbodies, reservoir for massive fine-grained sandstone with silty mudstones or mudstone deposits.

骨架砂体为分流河道，储层为块状细粒砂岩夹粉砂质泥岩或砂泥岩互层沉积。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.
