Abstract

Civil Engineering

groundwater

piezometers

slope stability

preferential pathways

landslides

Piezometric response in several hillslope hollows was compared for small and large storms at sites in coastal Alaska and Japan. During smaller storms with dry antecedent conditions there was evidence of a "wedge" of groundwater accumulating from the base of the slope. For wetter antecedent conditions and larger storms, piezometric response was less affected by slope position, possibly because of the contribution of preferential pathways in the soil to groundwater fluctuations. Piezometric response was more rapid and generally higher in more dissected hollows.
