河口泥沙 meaning in English
estuarial sediment
estuary deposit
Examples
- Density currents generated by saline and fresh water interactions are also important in the transport of sediment in estuaries .
由盐水和淡水相互作用所产生的异重流，在河口泥沙输移中也是很重要的。 - Sedimentation and optimal operation of three gorge reservoir in yangtze river
永定河河口泥沙淤积对官厅水库供水的影响分析 - Study achievement appears as following aspects : ( 1 ) yellow river estuary gate river flow and tide flow mixed area is not keep standing deposition status , on special income water and sediment conditions , boundary conditions and oceanic power conditions , this area may on the scour status ; ( 2 ) observed from estuary sediment deposition distributing process : delta and sea offing area sediment deposition vary trend is similar , each part sediment deposition scale varies as wave shape ; ( 3 ) on estuary gate , affect the sediment deposition factors , primary factors are tide prop , the gate widens gradually , estuary gate have branches , brine induced flocculation . this paper study the estuary gate widen , estuary gate have branches to affect the river channel deposition in quantity ; ( 4 ) based on field measured data , for the first time , deduce the estuary sediment deposition and distributing regress formula which can estimate estuary different areas sediment deposition volume ; ( 5 ) this subject demonstrate the estuary delta coastline dynamic balance conception , build the relationship between the estuary income sediment with deposition land area , draw the following important conclusion : when estuary years - averaged income sediment keeps at 345 million tons , the delta coastline may on the dynamic balance status . ( 6 ) this subject firstly brings up estuary sediment optimized control conception , and has the primary study on the macroscopically optimized control conception method
研究认为： ( 1 )黄河河口口门迳流潮汐区域并非持续保持淤积状态，在特定的来水来沙、边界条件和海洋动力条件下，该区域可以处于冲刷状态； ( 2 )从河口泥沙沉积分配的过程来看：三角洲与滨海区泥沙的沉积变化趋势是基本一致的，各部位的泥沙沉积比例变化基本呈波动状态，且三角洲与滨海区泥沙的沉积比例与来沙量密切相关，基本成正比关系； ( 3 )在口门处，影响泥沙沉淤的因素主要集中在潮汐顶托、口门逐渐加宽、河口门分汊、盐水造成絮凝等，本报告主要对口门加宽，口门西妥理工大学工程硕士专业学位论文分汉对河道淤积的影响进行了定量分析: (一扣根据实测资料首次建立了河赎流路泥沙沉积分配的回归计算式，据此可以预估计算河口不同区域泥沙的沉淤量; 、 5 )本项研究首次论证了河口三角洲岸线动态平衡的概念，并建立了黄河河口来沙量与造陆面积的相关关系，得出了当河口多年平均来沙量维持在3 . 45亿t时其河口三角洲岸线则可能处于动态平衡状态的重要结论; ‘ 6 )本项研究首次提出了河口泥沙优化调控的概念，并对其宏观优化调控模式进行了初步探讨。 - This paper summarize the estuary sediment management methods also , analyze and the following aspects and give evaluations : estuary dredging and lead the flow , lead water to scour the river channel , build the xihekou reservoir , estuary gate deposition management , dike reinforced etc
本文还对河口泥沙的处理途径和措施进行了概括总结，对河口疏浚与导流、引海水冲刷河道、建设西河口水利枢纽、拦门沙治理、人工有计划改道和出汉、加高堤防和加固防护工程和挖河固堤工程等进行了分析评价。 - Yellow river estuary is typical weak tide and high sediment deposition estuary , the yellow river sediment transport and settling deposition process is the capital factor to determine estuary evolvement characteristics . any method provided for estuary management , there is no exception to have tight relationship with estuary sediment transport and settling deposition process . this paper summarized the yellow river estuary basic characteristics firstly , point out existing problem in this research domain
黄河河口系典型的弱潮多沙堆积性河口，黄河河口泥沙的输移扩散和沉积过程是决定河口演变发展特征的首要因素，黄河河口任何一项治理措施的提出，无一例外均与河口泥沙的输移和沉积分布状况存在密切关系本文首先对黄河河口的基本特性进行了概括总结，在简略回顾黄河河口泥沙输移与沉积的有关研究成果的基础上，指出了当前在此研究领域内存在的问题。
