VERTICAL DISTRIBUTION OF SEDIMENT UNDER WAVES

<正> Based on the theoretical and epxerimental studies, a distribution equation of sediment concentration at a water depth under the equilibrium condition is derived. In practical cases, there may be three distribution patterns of Sediment concentration. (ⅰ) Concentration is lower at the upper surface, higher at middle depths, and the highest at greater depths. (ⅱ) Concentration is higher at the upper surface, lower at middle depths, and the lowest at greater depths. (ⅲ) Coneentration is higher at the upper surface, lower at middle depths, and higher again at greater depths.Finally, a new concept of wash load under the wave action is discussed.
