Short summary
The objective of this study is to improve the reliability of large-scale hydrological models. In environmental policies, many decisions are based on prognosis simulated by models. The parameterisation of these models is challenging due to the scarcity of available data. Particularly, parameters of soil properties are rare, but have a strong influence on model results. To account for the heterogeneity of soil properties, we developed a methodology that does not need additional field data.
