- 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。
- 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。
- 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。
- The tide began to flow and our footprints were covered. 开始涨潮了,潮水遮住了我们的脚印。
- 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。
