channel scour的意思|示意

The depth of river channel scour 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。

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.

当支沟泥石流输入主河的泥沙量小于主河的输沙量时，主河河床将下切，并逐渐恢复山区性河流的特征。

The strong scour resistance and stability of the Banks and coming big floods always with high sediment concentration are the key fators for forming a narrow and deep channel in the lower wei River.

河岸抗冲稳定性较强，并经常出现高含沙量大洪水，是形成渭河下游窄深河槽的关键。

High velocity of flow channel in the bottom mat, mat extended length according to the cage height and maximum scour depth to determine.

流速大的河道应在最下部设置网垫，网垫伸出的长度根据网箱高度和最大冲刷深度来确定。
