Mitigation of landslide hazards:Case study of rainfall warning criteria

  • Rainfall is the main factor init iating landslide hazards.Because of the improvement of weather forecast technique many studies use rainfall warning criteria to prevent landslide hazards.Unfortunately, it is hard to use in practice owing to the inaccuracy of forecast, insufficiency of hazard historical data and uncertainty of geology.This paper analyzes the relationship between landslides and characteristics of rainfall.The results show that the suitable rainfall warning criteria should be developed in accordance with different landslide hazards and pattern of rainfall.Moreover, the integrated studies combining geomechanics, engineering geology and meteorology can improve the performance of rainfall warning criteria.Consequently, the inte grated studies about mitigation of hazards are the tendency toward hazard prevention.
