Therefore, the width of regulationline and the water level are depended on transport capacity.
因此，其整治水位与整治线宽度的确定，是与悬移质泥沙冲淤平衡的挟沙力所决定。

The regulationline type is an important parameter to waterway regulation work, but there is no better method to design it except working according to experience.
整治线型对航道整治工程设计施工的意义重大，以往多根据经验确定。

Based on the morphological characteristics of riverbed of tidal estuaries, a calculation formula for the widening rate of the estuarine regulationline is derived.
