  • In order to conduct adaptive water management for an entire watershed, long-term hydrologic conditions must be clarified. In particular, the hydrologic process related to snow plays an important role in cold, snowy regions such as Hokkaido. Therefore, reliability of estimations of snow accumulation and snowmelt are needed to perform effective water management, while evapotranspiration relating to the conditions of soil and vegetation is also needed to clarify the water budget in an entire watershed. This paper focuses on the hydrologic process reproduced by the Two-layer model that deals with the heat balance in the atmosphere, the vegetation layer and the ground surface, as well as the long-term runoff characteristics calculated by the Tank model. In the model, the hydrologic process was evaluated in relation to the conditions of snow pack and snowmelt. Specifically, the parameters of the Tank model were effectively fine-tuned by applying the Filter-separation AR method and the Newton-Raphson method. Thus, the proposed model gives a promise to reasonably estimate the hydrologic process in cold, snowy region.
