Flow velocity in the different scenarios (Phy = physical; Bio = biological), treatments and positions along the racetrack flume.

Data show the average for the canopy height (18 cm) ± SD. L, low shoot density; H, high shoot density and b, bare sediment. Flow velocity in the different scenarios (Phy = physical; Bio = biological), treatments and positions along the racetrack flume.本数据展示了冠层高度（18 cm）的平均值±标准差（SD）。其中L代表低植株密度，H代表高植株密度，b代表裸露沉积物。本数据涵盖不同情景（Phy=物理过程；Bio=生物过程）、不同处理组以及沿跑道式水槽各测点的水流流速。
