摘　　要：文中针对坝下水文站洪水流态不稳定的特点,从水面流速系数入手,着重分析了水面流速系数的多样性,提出对于坝下测站的特点可以采用流速分段式确定水面流速系数的方法。According to the instability characteristic of flood flow regime of hydrometric station under dam, the variety of water surface velocity is emphatically analyzed from water surface velocity coefficient, and the velocity segment mode is proposed to determine water surface velocity coefficient based on the characteristic of hydrometric station under dam.

关 键 词：水面流速 流态 系数研究
