怎样从控制沿岸总输沙率的观点去控制海滩的侵蚀,像公式(8)所表述的那样,沿岸总输沙率可用下式表示。 Q_x=c′d~2B(gdB sin2θB)(1/2)(10)此处C′是常数;而沿岸总输沙率可用破碎波水深或破碎波高来表达,破碎波的倾角和另外一些参数包括在公式(10)的常数C′中,此公式显示出如前解释的,沿岸总输沙率直接与沿岸波能分力成正比。控制沿岸总输沙率的设想,可以从海岸泥沙来源的变化提出来。对海岸泥沙来源减
How to control beach erosion from the standpoint of controlling total coastal sediment yield, as expressed in Eq. (8), can be expressed as follows. (10) where C ’is a constant, and the total sediment transport rate along the coast can be expressed as the depth of the broken wave or the height of the broken wave. The dip of the broken wave and some other parameters Included in the constant C ’of Eq. (10), this formula shows that, as previously explained, the total coastal sediment transport rate is directly proportional to the coastal wave energy component. The idea of controlling the total sediment transport along the coast can be put forward from the changes in the sediment source of the coast. The source of sediment on the coast minus
