[Objective] The early risk warning prevention and control platform for check dam systems under extreme rainfall conditions were studied for intelligent inspection of dams and protecting check dams from water damage and breakage, in order to provide professional, rapid, and accurate technical support for flood control management and early risk warning. [Methods] We developed a full-coverage and high-efficiency software system through the design and development of functional modules based on iVX language and using MySQL database. We used “family tree” theory and the FT-IWHR analysis program to determine the failure risk of check dam systems, and combined this with engineering practice. [Results] A check dam system early risk warning, prevention and control platform was established. The basic information for a check dam system, the inspection monitoring system, and the early failure risk warning system were applied to the daily risk management of check dam systems in a visual and mobile way. The platform was applied in Xiaogou small watershed, Xiangning County, Linfen City, Shanxi Province. [Conclusion] It is feasible to conduct early risk warning prevention and control in check dam systems through information construction. The method can provide a quick and intuitive information transmission platform that is convenient for staff to operate and manage check dam systems, and effectively prevent the risk of accidents in these systems.
