Simulation of flood processes in small watersheds based on the InfoWorks ICM model:a case study of the Yili Mountain Area in the Taihu Lake Basin
摘要
Abstract
It is difficult to accurately reflect the influence of hydraulic structures,such as bridges and culverts,on the flood routing characteristics of rivers when using traditional hydrological methods to derive the flood process in small watersheds in hilly areas.In this paper,through the application of Infoworks ICM model,the typical small watershed in Yili Mountain Area of Taihu Lake Basin is selected to construct the hydrological and hydrodynamic model.Meanwhile,hydraulic structures such as bridges and road culverts along the river course were generalized and incorporated into the derivation of the flood process.The results of model calibration and verification show that the deterministic coefficient between the flood simulation process and the measured process is greater than 0.90,the relative error of flood peak flow is less than 20%,and the peak current error can be controlled within 1 hour,which meets the accuracy requirements of model application and provides a technical support for the calculation of flood process in small watersheds in the hilly area.关键词
