基于半分布式GUH模型的台风期水库入库径流模拟
Reservoir inflow simulation during typhoons based on semi-distributed GUH model
摘要
Abstract
During typhoon periods,heavy rainfall is highly concentrated and intense,which renders watersheds susceptible to flood disasters.Accurate simulation of reservoir inflow runoff during this period is critical for scientific reservoir operation and flood control safety.Based on the General Unit Hydrograph(GUH)theory,a semi-distributed runoff simulation model was de-veloped.Two parameterization schemes,namely sub-basin-specific and basin-wide parameterization,were designed to system-atically evaluate the applicability of the GUH model for reservoir inflow runoff simulation during typhoon periods.Taking the Hedi Reservoir watershed in Guangdong Province as the study area,the watershed was divided into 8 sub-basins,and hourly rainfall data were extracted.Six typical typhoon events from 2006 to 2013 were selected for model calibration and validation.The results indicated that the GUH model with sub-basin-specific parameterization achieved superior simulation accuracy compared to the basin-wide parameterization across all validation events,with an average coefficient of determination of 0.71,demonstrating strong generalization capability.The GUH model provides stable simulation performance and reasonable flood peak response while maintaining structural simplicity.With relatively low data requirements,the model enables efficient simulation and is well-suited for rapid-response reservoir scheduling systems,providing technical support for flood control operation and reservoir manage-ment.关键词
