navigation water level的意思|示意

The microcomputer control system for flow and water level on the model by the standards of navigation water technology of the Yangtze River between two dams is presented in this paper.

本文主要介绍长江三峡两坝间通航水流技术标准试验模型流量水位自控系统。

In late autumn, when the low water level makes navigation difficult, visitors are driven to Yangdi, where they then board a boat for the trip downstream to Yangshuo.

在晚秋，当低水位使得航行艰难，参观者就被用车送到杨堤，然后他们登船顺流到阳朔。

During the construction of Three Gorges Project, in some part of the river, due to the change of water level in fluctuating backwater area, the difficulty of navigation is intensified.

三峡工程施工期变动回水区河段由于水位变化，使部分河段碍航情况加剧。
