Abstract: This paper discusses the impact of environment change on hydrological cycle, hydrological proc- esses and hydrological modeling. The paper starts with a review of the history of the hydrological models’ development, the current state and the main challenges. Emphases are then paid to the following issues: the non-stationarity of hydrological processes and the rainfall-runoff relationship, the transferability of hydro- logical models (structure and parameters) across time periods, across spatial regions, across spatial and time scales, and coupling of hydrological models with climate models.
