一、河道基本情况高村至陶城埠河道全长146公里,是1855年铜瓦厢决口以后形成的河道,属于游荡向弯曲发展的过渡段,弯曲段与直线段相间,弯曲率为1.31,是黄河下游各段中弯曲率最大的一段,但比长江的荆江段小(上荆江为1.7,下荆江为2.84),河身基本上还是比较顺直的。河床束范于两岸大堤之间,堤距一般为4—8公里,主槽平均宽0.73公里,河道平均比降为1.5。河床组成绝大部分为极细沙和粉
First, the basic conditions of the river GaoCaoTaoChengBu a total length of 146 kilometers, 1855 copper tile burst after the formation of the river, belong to the wandering transition to curved development, bending and straight line phase, bending rate of 1.31, is The section of the lower reaches of the Yellow River, with the largest curvature, is smaller than the Jingjiang section of the Yangtze River (1.7 for the Jingjiang River and 2.84 for the Lower Jingjiang River), and the rivers are basically straight. River bed bundle Fan in the two banks of the embankment, the embankment is generally 4-8 km, the average width of 0.73 km main channel, the average ratio of the river is 1.5. The vast majority of riverbed composition is very fine sand and flour
