Research Abstract

In this study, more advanced measurement technique for accurate estimation of rainfall profiles and water mass balance in slopes during torrentialrainfall (so-called guerrilla-like rainfall) was developed to investigate the mechanism of rainfall infiltration and rainfall-induced surface failure. The advanced numerical simulation tools were also developed to evaluate the slope stability and simulate the slope failure/collapse processes during torrential rainfall. The newly developed numerical simulation tools were applied to the real surface failure in the slope and their validity was investigated.
