Conclusions

The 14 papers in the Special Issue present novel developments and perspectives in catchment hydrological modelling enhancing our understanding of hydrological processes and contributing to solving real-life problems. The wide spectrum of approaches described in the papers illustrates that improved understanding of hydrological processes is not limited to better process equations but also can be achieved through model evaluation including one or more of the following approaches: tests on multiple catchments with varying hydrological regimes, calibration using multiple data types, analyses of alternative model structures and uncertainty analyses.
