| Research Abstract |
In order to capture the ongoing drought and flood events globally and to detect the forthcoming risks, real time simulations were conducted using a global water resources model termed H08 and frequently updated global meteorological data. First, we conducted a hydrological simulation for 30 years in the late 20th century and evaluated the reproducibility of major drought and flood events of the largest river basins in the world. The results indicated that major flood events were fairly reproduced. Next, we developed a system that regularly retrieves the global meteorological data by JCDAS and successively update simulations. The system enables us to simulate up to two days before present. This is a first step toward the realization of early warning for droughts and floods using global water resources models
