Research on Simulation Method for Incoming Flood of Tianyi Reservoir Considering the Influence of Karst Geomorphology
Published 2022-01-01“…The karst in karst areas leads to a more complex runoff formation process,and the construction of water conservancy projects has aggravated the complexity and uncertainty of the production and confluence process in the basin.On this basis,a semi-distributed incoming flood simulation model of Tianyi Reservoir in the Nanpanjiang River was built by the Xin'anjiang model for karst geomorphology,considering the influence of upstream karst geomorphology.The results reveal that:① the built Xin'anjiang model for karst geomorphology can well simulate the incoming flood process of Tianyi Reservoir,and the simulation accuracy index of each zone is greater than that of the traditional Xin'anjiang model;② the Nash-Sutcliffe efficiency (NSE) coefficient in the series incoming flood simulation of Tianyi Reservior based on the model constructed in this paper is greater than 0.86 during both the calibration period and the validation period,and the volume error is within 12%,which indicates that the simulation results of the constructed model are good;③ the forecast accuracy is evaluated for six typical incoming floods of Tianyi Reservoir from 2018 to 2020,and the evaluation suggests that the built zonal forecast scheme meets the specification accuracy requirements.Thus,the results of the study can provide a reference for hydrological simulation in the upstream karst area of Tianyi Reservoir.…”
