This is caused by the tidal diffusion asymmetry in which the verticalturbulence diffusion in the ebb tides is weaker than the one in the flood tides.
动力分析表明这是由潮扩散的不对称性造成的，即落潮期间垂向湍流扩散比涨潮期间弱。

The turbulence intensity increases after the floodplain is vegetated. The lateral and verticalturbulence intensities are in the same order and follow the S-shape distribution law.
滩地种植植物后，水流的紊动强度增强，纵向和垂向的紊动强度相当，都服从S型分布。

Less turbulence would not only lead to less vertical mixing and therefore less climate impact, but also would be more efficient for energy generation.
