River simulation technology plays a crucial role in watershed digital twin.However,current precise mod-elling of physical rivers to virtual watershed faces several deficiencies.To address such deficiencies,a 3D hydrody-namic model was developed in this study based on terrain measurements,remote sensing images,hydrological data,and water surface line calculated by hydrological model.The UE5 engine and Fluid Flux plug-in rendering was em-ployed in the model.Blueprints were reconstructed and compiled,data assets were trained and coordinate system disparities were reconciled to finally achieve high fidelity simulation of the water flow of Hudu River.Calibration re-sults indicate that the present model accurately reflects real-world conditions with small errors.The simulation model depicts the water flow dynamics during different periods,the relative height difference between water level and em-bankment,the artificial flood diversion blasting,and underwater scenarios.Parameter adjustments enable compara-tive analysis of different scenarios,offering visualization support for flood control decision-making.
