Abstract Water level variations have caused numerous dam slope collapse disasters around the world, illustrating the large
influence of water level fluctuations on dam slopes. The required indoor tests were conducted and a numerical
model of an actual earth-filled dam was constructed to investigate the influences of the water level fluctuation rate
and the hysteresis of the soil–water characteristic curve (SWCC) on the stability of the upstream dam slope. The
results revealed that the free surface in the dam body for the desorption SWCC during water level fluctuations was
higher than that for the adsorption SWCC, which would be more evident… More >
