【摘要】 采用我国《海港水文规范》公式和美国《海岸防护手册》的CERC公式对石臼湾的沿岸输沙率进行计算;石臼湾南部的净输沙率约为11～15万m3/a,输沙方向自南向北;湾中部净输沙率约为1万m3/a,方向自北向南,两者作用的结果将在湾中部形成淤积,实际情况亦如此。规范公式的计算结果要小于CERC公式,两者的比值在1～0 5左右变化,且随着深水波高的增大而减小。更多还原

【Abstract】 Longshore sediment transport rate of Shijiu Bay is calculated with the formula of Seaport Hydrology Criterion and the CERC formula of Shore Protection Manual. The net volume silt discharge rate is about 11×104～15×104m3/a (South to North direction) in the south bay while about 1x104m3/a (North to South direction) in the middle bay. Both factors result in siltation in the middle bay, which accords with practical circumstances. The calculated value by criterion is less than that by CERC formula and the ratio of them ranges from 1 to 0.5, which decreases with the increase of wave height.更多还原
