logarithmic law

The results reveal that the sectional velocity distribution deviates from the logarithmic law in the core flow area. Meanwhile, the influence of roughness ratio of ice-cover bottom to bed, bed relative roughness and Reynold number on velocity distribution pattern is indicated.

研究结果表明，冰盖下水流的纵向流速在流动核心区并不遵循对数分布规律，同时揭示了冰盖底部与河床的相对粗糙比、河床相对粗糙度及雷诺数对流速分布规律的影响。
