闽江潮汐河口汊道浅滩整治

闽江河口属多岛式强潮河口,河道内多有汊道,在汊道口或汊道内均出现有浅滩,水深一般都在2.5 m左右,严重阻碍了船舶的通航,为此对闽江通海航道进行了一期和二期整治。通过整治各浅滩水深都有较大幅度的提高,取得了整治工程的成功。文中介绍了闽江河口水文泥沙的形势,并着重介绍了汊道浅滩整治成功的实例。

Regulation of Branch Channel Shoals in Minjiang River Tide Mouth

Minjiang River belongs to multiple islands strong tide river mouth. There are many branch channels in this river, and there are shallow shoals in bifurcation or branch channel, where the water depth is 2.5 m generally, which impeded seriously ships navigating. So the 1st Stage and 2nd Stage Regulations of the seaward channel of Minjiang River have been conducted. After regulation, the water depth of shallow shoals has been deepened in a large range, and achieved success of regulation project. In this paper, the hydrology and sediment situation of Minjiang River Estuary is introduced, and emphasized the success examples of branch channels regulation.
