In order to resolve these problems, the setup of intelligent pre-warning system of debris-flow is very urgent. Moreover, three steps of work might carry out and first is automatically record instead of manual observation, second is real-time analysis and feedback, and third is applying Internet of Things and Big Data to automatically revising each evacuation warning value.全球氣候變遷極端降雨事件土石流預警物聯網智慧化防災global climate changeextremely rainfall eventdebris flowpre-warninginternet of thingsintelligent pre-warning system of debris-flow
