Runoff simulation by modified SWAT model with multi-source remote sens-ing images of river parameters
Runoff simulation is of great significance in the fields of water resources manage-ment,flood forecasting and agricultural irrigation.By simulating and predicting hydrological processes,sustainable water resources utilization and management can be promoted.The Lishui River Basin is taken as the research area,and the multi-source remote sensing image data is used to extract the main channel parameters of the Lishui River Basin.The modified channel parame-ters are applied to the SWAT model and the runoff simulation experiment is carried out.By comparing and analyzing the runoff simulation results of the original model and the improved model,it is found that the modified SWAT model shows better accuracy and precision in runoff simulation.The NSE of the runoff simulation values of Jinshi station and Shimen station in the verification period is 0.84 and 0.80,and the R2 is 0.78 and 0.83.
