- Two thirds of the world's total sediment transport to the oceans occurs in South and East Asia, UNEP said, and deforestation is adding to soil erosion and sediment loads in waterways. 凡得瓦表示,会议也希望促成政府、民间社团、地方政府、私人企业及其他非政府组织间的更多合作和联盟。
- total sediment load 总含沙量
- As all dams result in reduced sediment load downstream, a dammed river is said to be “hungry” for sediment. 水坝还会成为动物在上下游栖息地之间迁徙的障碍,比如美国和欧洲的鲑鱼。
- Adoptive constant discharge is 3 cm3/s. Suspended sediment load is 4.5 g/min in the first 3 hours and 1.2 g/s thereafter. 采用的定常流量为3 L/s;悬移质输沙量在前3小时为4.;5g/min;其后为1
- 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。
- According to Dou Guoren's similarity theory of total sediment transport modeling for estuarine and coastal regions, a generalized physical model of the north-trough of the Yangtze River Estuary deep channel is designed. 摘要根据窦国仁波浪潮流共同作用下的全沙模型相似理论,设计了长江口深水航道北槽概化物理模型。
- This article studies the characteristics of the water & sediment load from 1960 to 1997 and the longitudinal & transversal bed profile from 1977 to 2002 by employing statistic analysis. 本文利用黄河下游1960-1997年的水沙资料和1977-2002年的断面资料统计分析了黄河下游水沙历年、汛期和脉动变化特点以及主槽平均河床高程和河相系数变化特点。

- variety of discharge and sediment load 水沙变化
- The total sedimentation was that rivers were branching and migrating frequently,and the sedimentary structures and fossil of ichnite were growing generally. 其总体沉积特征为:河道频繁分支与迁移,发育各种沉积构造及生物遗迹化石。
- water and sediment load variation 水沙变化
- Finally, the soil erosion moduli were calculated in 34 subbasins delineated by the SWAT, and the effects of different landuse types on sediment loads were analyzed. 通过计算34个子流域内的侵蚀模数,对流域内的土壤侵蚀强度进行了分级,并分析了不同土地利用方式对产沙的影响。
- matching of flow and sediment load 水沙搭配
- Test Method for Determination of Total Sediment in Residual Fuels 测定剩余燃料中沉积物总量的试验方法
- The mass rally was a total fiasco. 那次群众集会彻底失败。
- I must say the news comes as a total surprise. 我得说这个消息来得太突然了。
- Ten years was the sum total of my education. 我受教育的年限加起来共十年。
- Variation trend of runoff and sediment load in Yangtze River 长江水沙变化发展趋势
- My small contribution was lost in the grand total. 我的小小捐献在巨大的总额中小得几乎看不见。
- The ship was wrecked and became a total loss. 船只失事,一切都损失了。
