Abstract For a more accurate understanding of the impact of climate change and human activities on the hydrological cycle, a hyper-resolution global water resource assessment is necessary. Functions such as intergrid water transfer and medium-sized reservoir operation, which are essential for hyper-resolution simulations, are also available in the latest version of global hydrological model H08. In this study, we conducted a series of global hydrological simulations at spatial resolution of 5 minutes and 0.5 degrees in H08. By comparing the model responses with different resolutions, we obtained insight into the importance of water allocation functions and changes in water withdrawal sources in a hyper-resolution global hydrological model. In addition, our results showed a certain level of feasibility of water supply and demand assessment in large irrigation areas and large cities by using the hyper-resolution global hydological model.
