Conditions leading to rainfall-induced debris flows were investigated by a field study of the hydrologic response and a laboratory testing program of soil strength and behavior. The laboratory test program consisted of direct shear (DS) tests, isotropically consolidated undrained (ICU) triaxial tests, anisotropically consolidated undrained (ACU) triaxial tests and field stress path (FSP) tests.
