Abstract

In this paper we propose the use of a distributed rainfall-runoff model for a real-time forecast of shallow landslides. The proposed model calculates the distribution of soil water in each 50 m grid cell and predicts the factor of safety using the soil-water information, slope angle and soil properties at each cell. For the landslides in the upper Abukuma River basin caused by heavy rainfall in August 1998, the forecast model was able to display the dangerous areas a few hours before actual landslides occurred. The calculation completed in about 20 seconds after the input of rainfall. Although the forecast contained some errors, the model would provide useful information for the reduction of landslide disasters.
