- flow and sediment process 水沙过程
- Since there are no large fluctuations in stream flow and sediment concentration in a lower-water season, the real process on the river network can be simulated by the steady solution of the model. 考虑枯水期水沙动力学过程类似于固定流量和含沙量条件下的稳态,用该模型模拟预测了水流携沙系数(表征携沙力)和冲淤量沿河道分布的标度规律。
- flow and sediment processes 水沙过程
- Evident backward erosion had appeared in the coastline of the delta region in recent years owing to decreaseof flow and sediment from the Yellow River. 近年来黄河来水来沙呈递减趋势,现行河流路海岸线淤进减缓,原行河流路海岸线出现了严重的蚀退。
- This model is used to simulate the movement of flow and sediment in Shashi reach in Yangtze River. 模型较全面地考虑了非均匀悬移质及推移质运动,具有较好的普遍适用性。
- The runoff and sediment volume increased with the increase of the overland flow and slope. 随着降雨量和坡度的增大,各地类径流量和泥沙量也随之增大。
- The trends of water flow and sediment changes at three hydrographic stations (Pingshan, Beibei and Yichang) in recent 50 years are analysed. 摘要初步分析了长江上游屏山站、北碚站以及宜昌站近50年来的水沙变化趋势。
- The massive computing is required since that the digital watershed model discussed in this paper is aimed to simulate the distributed hydrological and sediment process in a large-scale watershed. 数字流域模型因需要对大范围流域进行分布式的水文、泥沙过程模拟而提出了较大规模的计算需求。
- In a special circulating system with high velocity flow, boundary shear stresses in clear water flow, aerated flow and sediment laden flow are measured. 在高速水流循环系统中,用自行研制的剪切力传感器分别量测了清水、掺气水流及挟沙水流壁面上的剪切力;
- The formation condition, movement of flow and sediment as well as the characteristics of fluvial processes for different kinds of estuaries are analyzed. 随后对不同类型河口的形成条件、水沙运动和河床演变特征进行了初步分析。
- By means of mathematical models of wave, tidal flow and sediment, numerical study is carried out on deposit-promoting schemes in the reclamation project of Wenzhou shoal at Oujiang estuary. 建立了波浪潮流泥沙数学模型,对瓯江口温州浅滩围涂促淤工程效果进行了数值模拟研究。
- By jointly dispatching the input and output flow and sediment, the implementation of this scheme successfully formed the density flow and reduced the sediment deposited in reservoir. 通过水库水沙联合调度实践,2004年成功塑造异重流并排沙出库,达到了减少水库淤积、优化出库水沙组合等多项预期目标。
