Abstract In order to improve the water management in the farmland and reduce the influence of waterlogging damage on crops, the intelligent warning system for farmland waterlogging was designed based on the real time monitoring of water information in crop root areas. The system is composed of 6 parts: water information sensor, data acquisition and wireless transmission module, data processing module, farmland damage prediction and disaster release module, which can continuously monitor farmland water accumulation and soil moisture status, and transfers the data through the wireless transmission system, then evaluates and forecast the waterlogging. Based on the field experiments, parameters in the mathematical model are determined, and a method for evaluating and predicting farmland waterlogging damage is proposed. Result of application indicates that the real time monitoring results and warning accuracy can meet the demand of farmland water management, and moreover the monitoring module of this system is small and portable, and the software module has friendly interfaces and simple operations. Applicating this system has the striking effect on improving the drainage management level and reducing the damage of farmland waterlogging.
