Abstract��
Shangyao valley is located in Jin'an village of Songpan in Sichuan�� Many material sources are accumulated in valleys�� The debris flow will be triggered by a rain storm with short-duration and strong intensity�� which may threaten people's lives and property in downstream�� Based on the investigation��the formation conditions of debris flow and its dynamic characteristics are analyzed and its hazard assessment is investigated�� Research shows that there is the potential cause of debris flow in Shangyao valley��which is of the middle risk class�� |
