Abstract
To assess climate change impacts and study adaptation measures in the water sector, development of macro scale hydrological model covering an entire nation or a vast regios is effective. By using the H08 global water resources model, one may efficiently proceed model development in data scarce regions. In this study, we applied H08 to the Kyusyu Island, Japan, and found the past observed hydrology was well reproduced with a standard simulation protocol which was originally designed for major continental rivers in the world. Then we extended our knowledge on the relationship between the observation density of input meteorological data and the simulation performance utilizing the benefits of good availability of accurate input and validation data.
