黄河河口清水沟流路自1976年5月行河以来,滨海淤积的宽度约53km,单一沙嘴主体淤积宽度25km左右。1976年至今平均每年造陆面积为43.5km~2。与其它流路相比清水沟流路排沙比较小,这主要是由于清水沟流路行河期间入海泥沙中粗沙比例较大,入海日附近海域潮流弱。沙嘴突出海域后(?)排沙比未见增大,除来沙较粗的原因外沙嘴南偏不利于泥沙向外海输送也是重要因素。
Qingshuigou Channel of the Yellow River Estuary Since the river was launched in May 1976, the width of silt in the coastal area is about 53km, and the sedimentation width of a single spit nozzle is about 25km. Since 1976, the average annual land area of 43.5km ~ 2. Compared with other flow channels, the sediment discharge of the Qingshuigou channel is relatively small, which is mainly due to the large proportion of coarse sediment entering the sea during the Qingshuigou route and the weak currents in the waters near the days of entering the sea. After the sand spout protruded sea area (?), The sediment discharge ratio did not increase. Except for the reason that the sediment was thick, the south spur was not conducive to the sediment transport to the open sea.
