| Abstract | In this study, a new predicting models that can considering the quantitative effect of antecedent rainfall on shallow landslide for shallow landslides prone area predicting at the basin scale. The hillslope hydrology model is used to construct the relationship of antecedent rainfall to the height of ground water, the infinite slope stability theory is used to construct the relationship of antecedent rainfall to slope stability. At last, the model was applied at a basin area. Comparisons are made between considered and unconsidered antecedent rainfall. The results show that in the basin area, the shallow landslides prone area for considered the antecedent rainfall is larger than that unconsidered the antecedent rainfall. It is can be concluded that the antecedent rainfall is quite important and should not be ignored in shallow landslide hazard assessment. |
