The depth of river channelscour is calculated by the scour rate and scour time.
河道冲刷深度主要决定于冲刷率和冲刷历时。
2
Because the pipeline diameter in platform is one third of that in tidal channel, so the limit scour length is less.
而平台区由于设计管径仅为潮汐通道区的三分之一,其极限冲刷长度远小于潮汐通道区。

The main channel bed will scour if sediment amount from tributary debris is less than that the main stream can carry and the river evolution exhibits the characteristic of mountainous rivers.
