| 1. | When flow velocity decreases below the corresponding incipient motion condition, no sediment movement occurs .
当水流速度小于相应的起始运动时，将无泥沙运动。 |
| 2. | Despite this attention; only modest progress has been made in the basic understanding of the bed phenomena and their relation to sediment movement .
尽管受到注意，但床面现象及其对泥沙运动的关系的基本理解却仅有不太显著的进步。 |
| 3. | Analysis on flow and sediment movement in approach channels of tidal river branches

| 7. | Considering the effects of both tides and waves , a2 - d numerical model was used to simulate the sediment movement in lianyungang harbor , and a large scaled average sediment concentration field of hai - zhou bay was computed
摘要以连云港进港航道为例，应用波浪、潮流共同作用下的二维泥沙数学模型，研究淤泥质海岸的泥沙运动及航道回淤问题。 |
| 8. | Finally , the equations of the velocity when the particles start to move , suspend and stop were gotten from the rule of silt sediment movement . the velocity with no depositting was gotten from a equation of silt sediment movement in drainage
最后又借用泥沙运动方面以及污水管道内泥沙运动方程的知识,得出了不同管径下颗粒的起动、扬动、止动流速与管道运行临界不淤流速。 |
| 9. | Based on the prototype observation and model test made for the periodic - flushing de - silting basin , the process and the division of the three - stage hydraulic flushing are put forward on the basis of the feature of water - sediment movement , and then the calculation formulas and the related parameters for the stages of emptying flushing ; retrogressive flushing and the flushing along the basin are given as well
