Based on the climatic conditions and flood characteristics of the Puhe River Basin, this paper used Tank model to simulate 10 rainstorm flood processes in the basin from 2019 to 2020, constructed a conceptual rainstorm flood meteorological risk early warning model suitable for the basin, and carried out simulation and accuracy evaluation. The results show that the improved water tank model can intuitively simulate the water level change process curve of Shijiao hydrological station under different time scales and different basic water levels, reduce the uncertainty of area rainfall threshold, and the prediction accuracy is class B; Meteorological risk warning is issued level by level according to the simulation results, and the skill score and hit rate are 100%; The average early warning release time is more than 3 hours in advance, which can be substituted into the predicted precipitation to further extend the flood forecast period.
