A PRELIMINARY STUDY ON LAND RESOURCES OF THE WATER LEVEL FLUCTUATING ZONE IN THE THREE GORCES RESERVIOR;
the high [low] watermark
(涨 [落] 潮时的) 最高 [最低] 水位标
A rough idea of the annual rainfall can be assumed from previous years, but the fluctuation in the rate of intensity of rainfall during a storm is unpredictable.
New Method of Single-valued Stage Discharge Relationship Effected by Flood Rise and Fall
Experimental study on the pile bearing capacity under the condition of reservoir water level fluctuation
A barrier constructed across a waterway to control the flow or raise the level of water.

(of the tide)start to come in or go out
The tide ebbs and flows twice in 24 hours.
tail up and down the stream
Every tide have its ebb.
Study on the Mechanism of Water-Rock Interaction and Stability Analysis under Rainfall and the Fluctuation of Reservoir Water Conditions for Reservoir Landslides;
Water level upstream is higher than that downstream during the ebb tide, and water level descent of ebb tide is one order bigger than that of flood tide.
The ventilation of a sewer is vital to prevent the concentration of dangerous and offensive gases and sudden fluctuations in the sewage level
That spring, after a whole week's rain, the river rose.
The rise and fall of the sea is governed by the movements of the moon.
