Role of topography in the behavior of the matric suction of unsaturated fill slopes
Abstract This paper presents the result of a field study on the influence of topography on the distribution of the matric suction of the soil in unsaturated slopes subjected to rainfall. The matric suction was measured in the lower, middle and upper parts of planar, ridge-like and gullied slopes before and after two significant rainfall events. Jet-filled tensiometers were used for depths of >1.2 m and the filter paper method at depths of <0.9 m. It was found that in the dry season the matric suction of the soil at a shallow depth in the gullied slope is significantly less than that in the planar and ridge-like slopes while following a rainfall event the decrease in the matric suction is smallest in the gullied slope and greatest in the ridge-like slope, irrespective of the amount of the accumulated precipitation.
