Abstract: Current water revetment design focus only on landscape and ecology, there is the lack of study on the influence of the dynamic change of water level on revetment seepage field and the stability. On the basis of hydrogeological data of Lishui River during 2007-2012, from the angle of the rate of change of dynamic revetment level, slope safety factor, the variation law of revetment stability was studied for different rates of rise and fall of water level. Studies show that the dynamic change of water level had significant effect on revetment seepage field. Water level changes fast, free water surface of revetment lags more obviously. When the water level rises in revetment, the stability coefficient is from large to small and then stable. With the gradual decrease of water level, stability coefficient of revetment decreases firstly, when the water level reaches a certain height (minimum stability factor at this time), stability coefficient rises again gradually. The conclusion of the research can be used to guide the water revetment design and has practical significance for the safe operation of the water revetment under conditions of dynamic change of water level.
