Subsurface drainage has been widely accepted to mitigate the hazard of landslides in areas prone flooding. Specifically, use wells with pumping systems recognized as an effective short-term solution lower groundwater table. However, this method not well considered for long-term purposes due potentially high labor costs. This study aims investigate idea autonomous system subsurface by leveraging...

The effect of preferential flow on the stability of landslides is studied through numerical simulation of two types of rainfall events on a hypothetical hillslope. A model is developed that consists of two parts. The first part is a model for combined saturated/unsaturated subsurface flow and is used to compute the spatial and temporal water pressure response to rainfall. Preferential flow is s...
