基于模型参数移植的广西北部湾入海河流径流模拟
Runoff Simulation of Rivers Entering the Sea in Beibu Gulf,Guangxi Based on Model Parameter Transplantation
摘要
Abstract
Runoff from rivers entering the sea is critical to maintaining the ecological balance of the bay.In this study,the neighboring basins of Beibu Gulf that connect to the sea,namely Nanliu River and Qinjiang River,were used to simulate runoff using the SWAT hydrological model and validate the applicability of the model parameters between the two basins using the cross-transplantation method.The results indicate that:① The SWAT model can effectively simulate the monthly runoff of the Nanliu River and Qinjiang River basins,with Nash-Sutcliffe efficiency coefficients(NSE)greater than 0.83 and coefficients of determination(R²)greater than 0.84 during both the calibration and validation periods,as well as a relative error(PBIAS)of less than±12%.The simulated average annual runoff depth ranges from 763 to 1 033 mm,with the Qinjiang River being higher than the Nanliu River.② After parameter cross-transplantation,the simulation results are satisfactory(NSE values for the Nanliu River and Qinjiang River are 0.845 and 0.828;R² values are 0.909 and 0.846,and PBIAS values are 16.0%and-14.5%,respectively),which verifies the feasibility of cross-transplanting the SWAT model parameters for runoff simulation in the two basins.The hydrological model parameters of adjacent basins in Beibu Gulf,Guangxi can be used for runoff simulation.关键词
