您要查找的是不是:
- river channel sedimentation 河道淤积
- The sediment load entering the Lower Yellow River is so larger than that transported to the deep sea that the siltation of the river channel and esturay is unavoidable. 由于进入黄河下游的沙量远大于能输往深海的沙量,黄河下游河道及河口的整体淤积是不可避免的。
- Next autumn, we will dig and dredge this river channel. 明年秋天我们就要开浚这个河道了。
- When WRT is reduced from 15km to 10km, the reduction of WRT has no influence on channel sedimentation rate. 当堤距由 15km缩窄到 10km时 ,堤距的缩小对沉积速率不发生影响 ;
- Comparing with the origin shape,the dredged channel can maintain narrower and deeper in a long time,which indicates that the river channel dredging is beneficial to sediment deliver and flood control. 挖槽河段在很长一段时间内保持比原平衡河道较窄深的断面形态,说明挖槽疏浚对河道输沙和洪水灾害防治是有利的。
- Self-formed river channels tend to be sinuous. 自动形成的河槽是趋向于弯曲的。
- Believed to be river channels or canals. 相信这些可能是河道或运河。
- Mud gravel is often found in the base of distributary channel sediment,plant root and lignite often develop in the swamp sediment. 三角洲平原分流河道沉积底部泥砾较发育,沼泽沉积中发育植物根和褐煤沉积;
- sediment accumulation on river channel 河道增淤
- Building structures within river channel or on river beaches is prohibited without approval from relevant competent departments. 未经有关主管部门批准,不得在河床、河滩内修建建筑物。
- sediment transport capacity of river channel 河道输沙能力
- Then workers opened a freshly dug river channel that?stranded small fish in ponds and marshes. 后来,工人挖开一条新河道,不料将池塘和沼泽中的小鱼困住。
- In the meantime, inside certain limit, the limit cost that inland river channel provides a service is 0 or dinky. 同时,在一定的限度内,内河航道提供服务的边际成本为零或极小。
- The mineral water resource origins from the Helong city East City Town Bapu River channel without pollution. 该矿泉水水源地地处和龙市东城镇八浦江沟,无污染。
- Chen Dong,Cao Wenhong and Hu Chunhong, On the Threshold of River Channel Shrinkage, 29th IAHR Congress,Beijing, 2001. 程义吉、曹文洪、陈东,黄河口挖河疏浚道路风沙污染分析,泥沙研究,2001年第4期。
- The lower reach of the Shing Mun Main Channel was originally a part of Tolo Harbour, but reclamation transformed it into a river channel. 城门河主河道下游原为吐露港的一部分,填海后才成为河道。
- After the river channel shifted, the discharging center of pressure was generated from the seabed erosion, on which the diapir came into being. 黄河口摆动后,海底快速冲刷,在最大冲刷中心也是最大压力释放中心刺穿体形成,随着海洋侵蚀速率减缓,刺穿作用将逐渐减弱,最终将被冲刷消亡。
- In coal-seam roof, distributary channel sedimentations mostly are vertical accretion, and the continuity of sand body evolvement is well. 顶板分流河道沉积作用以垂向加积作用为主,岩体演化具有较好的继承性;
- In this paper, the design scheme and calculation method of tailwater gate hoist bridge at power station in river channel was introduced. 简要介绍了黄河沙坡头水利枢纽工程河床电站尾水门机桥的设计方案和计算方法。
- To steady the Yellow River channel into the sea and to delay the floodtime of present Qingshui gully, the artificial outlet of Qing 8 was realized. 为稳定黄河入海流路,尽可能延长现行清水沟流路的行洪时间,进行了清8人工出汊。
