一、引言不少港口的入海航道都是位于浅滩水域之内.就淤泥质浅滩而言,因其组成物质较细,水下岸坡十分平缓,浅滩航道往往较长.淤泥质浅滩又与沙质浅滩不同,受到波浪和水流扰动的底部泥沙,大多以悬移质的形式悬浮于水中,为水流携带搬移.我国淤泥质海岸长达1800多公里,随着四化建设的飞速发展,各地正在加速建设新的港口,因此,对淤泥质浅滩航道的回淤进行估算,有着十分重要的意义.

I. INTRODUCTION In many shallow sea ports, the inlet channels of many ports are located within the shallows waters. In the case of silt shallow shoals, because of their fine composition, the underwater bank slopes are very gentle and the shoal channels tend to be long. In the shallow shoal, the bottom sediment, disturbed by waves and currents, is mostly suspended in water as a suspended sediment, which is carried by the water. The silt coast in China is over 1,800 km long. With the rapid development of the four modernizations, Is accelerating the construction of new ports. Therefore, it is of great significance to estimate the siltation of the silt shoal channel.
