摘要

水文模型正在成为自然资源规划和管理的基本工具;然而，由于缺乏校准和验证数据，它们的应用受到阻碍。因此，本研究的目的是对SWAT模型在下马哈纳迪河流域进行标定和验证。使用SWATCUP进行敏感性分析、校准和模型验证。在灵敏度分析的基础上，利用SWAT-CUP对12个参数进行了标定。模型性能指标(R2、NSE和PBIAS)在校准时分别为0.76、0.78和6.6，在验证时分别为0.79、0.74和7.8，结果令人满意

Sensitivity analysis, Calibration and Validation of SWAT model for the Lower Mahanadi River Basin

Hydrological models are becoming a fundamental tool for natural resource planning and management; however, their application is hampered by a lack of data for calibration and validation. Therefore, the aim of this study is to calibrate and validate the SWAT model in the Lower Mahanadi River basin. The SWATCUP was used for sensitivity analysis, calibration, and validation of the model. Based on the sensitivity analysis, twelve parameters were calibrated by the SWAT-CUP. The model performance indicators (R2, NSE, and PBIAS) showed satisfactory results with 0.76, 0.78, and 6.6 during calibration and 0.79, 0.74 and 7.8 during validation, respectively
