The Jiangjiagou ravine, located in the Xiaojiang River Basin, was a frequent landslide occurring area. In 1961, an observation and research station of debris flows, known as Dongchuan Station, was established in Jiangjiagou area. Since then, several generations of researchers have observed and studied debris flows, and established a comprehensive disaster reduction model of "stabilizing, blocking and draining", which has laid the foundation of debris flow science in China.
A large-scale dynamic simulation experiment platform for mountain disaster was recently put into use in Dongchuan Station. The completion of this scientific device will reveal the natural law of debris flow outbreak, tackle the problems on prevention and control, and reduce the harm on human.
