该数据集包括对单株盐沼植物所受力以及植物草甸上的水流结构和波能耗散的实验室测量结果。单株植物实验（IE）中测得的数据表现为植物阻力和自由表面位移的同步测量值，以及三维速度剖面图的原始数据、相位平均数据和统计数据。草甸实验（ME）提供沿草甸 10 厘米和 15 厘米间隔的自由表面位移时变数据，以及草甸上游和草甸内部 1 至 2 厘米垂直分辨率的速度剖面图。此外，还计算并报告了每次测量的湍流动能以及所有条件下的波浪衰减系数。

The meadow experiments (ME) provide time-varying data of free surface displacement along the meadow at 10 and 15 cm intervals, as well as velocity profiles upstream of and within the meadow with 1 to 2 cm vertical resolution. In addition, the turbulent kinetic energy for each measurements and the wave decay coefficients for all conditions were calculated and reported.
