Focusing on island-type region

this article developes a model platform for comprehensive simulation and prediction of small island basin based on multi-source heterogeneous data

multiple hydrological and hydrodynamic models such as flood and tide

coupled with digital twin technology

with an emphasis on key technologies such as model accurate forecast scheduling and data interaction

realizing real-time accurate forecast and dynamic hierarchical early warning of small island basin. Taking the southern part of Dongtou District in Wenzhou City as the experimental area

after 6 months of actual operation verification

the model has achieved scientific and efficient prediction and accurate and effective scheduling

which can improve the ability of small basin torrential flood warning and the efficiency of island water resource utilization

and provide scientific basis for precise management of water resources in island-type region. The results have certain reference value for regions with similar island environments.
