Optimal structures of hydrological models for the regionalization of model parameters
Hydrological models are intended to describe runoff processes, depending on the characteristics of the basin areas. Universal models, however, are often over-parameterised. The large number of parameters with similar effects on the outcome results in equifinality. Often the model concepts can hardly be proved in reality as the scale problem (measurements can be done only at single spots, but have to be generalized over large areas) is a constrain. Therefore the regionalization of the model parameters is difficult. With step-by-step model extensions based on data and knowledge about the heterogeneity of river basins, this problem should be solved. The goal is to derive a model for unobserved basins with the knowledge of important properties of the watershed.
