丁坝冲刷长度的简捷计算

A brief calculation of erosion length for spur

  • 摘要: 本文根据丁坝作用后水槽中水流情况,采用动量方程结合试验资料,导出了丁坝下游主槽平均流速沿程变化的公式,以此为基础,提出了丁坝作用下河床冲刷段长度的计算公式。

     

    Abstract: According to the flow state in flume for spur and experimental data, the formulas for the mean velocity of main channel varying with distance downstream were derived with momentum principle. By using above formula, the erosion length of river bed for spur was discussed.
