main stream channel的意思|示意

The simulated results indicate that when the stream field begins steady, there is a steady main flow channel from the east part of the lake to the west part.

结果表明，在引水期水库的流场达到稳定状态时，水库流场有一个自东向西的水流主要通道。还对水库出口处有初始水体流速的情况进行了模拟。

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。

In the inner shelf, the main geomorphic types have the accumulational plain, shoreface terrace, ancient costal line, ancient stream channel, mamelon and pit-and-pots.

内陆架地貌主要有陆架堆积平原、水下阶地、古海岸线、古河道、小丘和坑洼群等；

The model is applied to forecast the variation process of main stream direction, cross section and channel slope of a conceptualized curved river under the erosion of clear water.

应用建立的水沙数学模型以及河岸冲刷模型，模拟了一概化弯道在持续清水冲刷下的主流线位置、断面形态、主槽比降的变化过程，模拟结果符合弯道演变规律。

内陆架地貌主要有陆架堆积平原、水下阶地、古海岸线、古河道、小丘和坑洼群等；

The second stage is to close the left bank main river bed, divert the stream to the right bank open channel and build the spillway section in the mian river bed and the powerhouse on the left bank.

二期工程围左岸主河床 ，右岸明渠 （建于一期 ）导流 ，建主河床泄洪坝段及左岸电站厂房。
