Abstract: As non-engineering measures for mountain flood prevention in county scale expand, important issues have raised concerning strengthening the collaboration among prevention projects, improving the emergency response coordination among provincial, municipal, and county level, and enhancing the disaster prevention and management ability. In this article, the overall design scheme of monitoring and early-warning system for mountain flood disasters in Leshan city is presented. The data sharing and collection among four levels are described, and the functions of system modules are expounded. The system involves data sharing and information acquisition subsystem, information query subsystem, monitoring and warning response tracking subsystem, and subsystem of mobile data transmission, query, monitoring and early warning. The complete system could offer reference for the construction of municipal-level flood warning system.
