摘要：已经建立了不同的 SWAT 模型来预测欧洲规模的排水量，应用了一种创新的建模协议，包括敏感性分析、多变量校准和校准参数的区域化。在本应用中，考虑了两个大区域：斯堪的纳维亚半岛和伊比利亚半岛，主要目标是：（a）研究为选定的子流域获得的校准参数集的空间变化，以及（b）识别每个区域中最相关的水文过程。分析结果强调，降雪过程在斯堪的纳维亚半岛占主导地位；地下水过程在斯堪的纳维亚半岛和伊比利亚半岛都很重要，而侧流在这两个地区都不重要。校准后的土壤水力参数在每个区域具有不同的值范围，反映了两个研究区域之间径流生成机制的差异。该分析的贡献是评估整个欧洲水文过程之间的主要差异以及了解污染物的主要传输路径。编辑 Z.W.昆泽维奇；客座编辑 V.

Abstract Different SWAT models have been set-up to predict water discharge at the European scale, applying an innovative modelling protocol that involves sensitivity analysis, multi-variable calibration and regionalization of the calibrated parameters. In this application, two large regions have been considered: the Scandinavian and the Iberian peninsulas, with the main objectives: (a) to study the spatial variation of calibrated parameter sets obtained for selected sub-basins, and (b) identification of the most relevant hydrological processes in each region. The results of the analysis highlight that snow processes are dominant in Scandinavia; groundwater processes are significant in both the Scandinavian and Iberian peninsulas, while lateral flow is not significant in either region. Calibrated soil hydraulic parameters have different ranges of values in each region, reflecting a difference in runoff-generating mechanisms between the two studied regions. The contribution of this analysis is the assessment of the main differences between hydrological processes across Europe and understanding of the major transport pathways for pollutants. Editor Z.W.
