| Abstract | Most of the Wenchuan earthquake affected areas had no debris flow before the earthquake, but abundant loose deposits induced by the earthquake have served as the source materials for debris flows, resulting in a dramatic increase of debris flow occurrences after the earthquake (2008-2014). Therefore, most of the earthquake affected areas have few rainfall and hazards data before. Moreover, a huge amount of loose deposits are present in the channels and slopes, causing dramatic changes on the environmental development for the occurrence of debris flow. The study of rainfall threshold has become more complex, and the traditional methods cannot satisfy the need for debris flow early warning and mitigation in these areas. |
