- Based on both shear force and stream power and through theoretical derivation, the incipient motion critical conditions of cohesionless uniform sediment are achieved. 通过理论推导,得出基于剪切力和水流功率的均匀沙起动临界条件表达式。
- The measured data show that the bedload sediment transport rate is related more closely to the effective stream power within the bed-surface layer than to the river stream power. 实测资料表明,推移质输沙率与床面层内有效水流功率有良好的相关性,且高于推移质输沙率与水流功率的相关性。
- The result shows that the stream power, mean velocity and grain shear stress are effective in predicting sediment transport rate and the unit stream power, Froude number and Velikanov parameter are better indexes for predicting sediment concentration. 结果表明 ,水流功率、平均流速、沙粒切应力能较好地预测输沙率而单位水流功率、佛汝德数、Velikanov参数则较好地预测输沙浓度。
