摘要：
This paper develops a slope susceptibility map for an Orchard district in Singapore using GIS-based prediction models. Regional-scale slope susceptibility was assessed based on the contributions of the important parameters, e.g., rainfall intensity, soil-water characteristic curve (SWCC), unsaturated permeability function, elevation and slope angle map as well as groundwater table spatial distributions. As a result, an appropriate slope susceptibility map was established by incorporating the unsaturated characteristics of soils.
