考虑融雪和降雨径流过程的网格化模拟方法及应用OA
Gridded simulation method considering snowmelt and rainfall-runoff processes and its application
针对目前考虑融雪的概念性水文模型大多为集总式水文模型这一问题,以网格新安江模型为基础,通过耦合融雪模块构建了考虑融雪和降雨径流过程的网格新安江模型(iRainSnowHydro 模型),以金沙江上游梨园流域和澜沧江上游乌弄龙流域为典型流域进行日径流模拟,并与集总式融雪径流模型(Hydromad 模型)进行对比分析.结果表明:iRainSnowHydro 模型在梨园和乌弄龙流域的日径流模拟效果均良好,率定期和验证期的决定系数和纳针效率系数均超过了 0.85,百分比偏差绝对值均小于 10%;iRainSnowHydro 模型的模拟性能优于 Hydromad 模型,且其分布式结构具有显著优势.
To address the issue that most conceptual hydrological models considering snowmelt are lumped models,a gridded Xin'anjiang model considering snowmelt and rainfall-runoff processes(iRainSnowHydro model)was constructed based on the gridded Xin'anjiang model by coupling a snowmelt module.Daily runoff simulations were conducted taking the Liyuan basin in the upper reaches of the Jinsha River and the Wunonglong basin in the upper reaches of the Lancang River as typical basins,and the results were compared with those of a lumped snowmelt runoff model(Hydromad model).The results indicate that the iRainSnowHydro model exhibits good daily runoff simulation performance in both the Liyuan and Wunonglong basins,with R2 and NSE exceeding 0.85 and the absolute value of PBIAS being less than 10%in the calibration and validation periods.The simulation performance of the iRainSnowHydro model is superior to that of the Hydromad model,and its distributed structure has significant advantages.
