The construction of flood evolution models for small and medium-sized rivers is often restricted by river terrain data.Through the refined digital terrain constructed by drones and remote sensing,a flood evolution model for the Gancun-Shangyao town section of the Zhuozhang river was constructed to simulate the evolution of multi-year floods in the area.The results show that:the greater the flow,the faster the flood evolution and the larger the inundation range.The cross-sectional flow is closely related to the inundation range,and small flow accumulation floods are prone to inundation.The flood risk of Shizidao village and Beidi middle school is the greatest.
