| 研究実績の概要 |
To achieve the 1st year’s target, I have finished downloading historical data from the ECMWF center. After that, decoding the original data for running the land surface model, MATSIRO, and CaMa-flood is finished from 2001 to 2020. Decoding ECMWF forcing data involves spatial and temporal downscaling. Simulation of the land surface model and CaMa-flood have been smoothly carried out. Using this forcing dataset, we successfully get more than eight days of forecasting, which is more than five times longer than our previous flood forecasting achievement (39 hours by MSM, in Japan only).These historical results will contribute to analyzing historical river water depth worldwide. The automatic system is partly built and will finish construction in the 2nd year.

理由
Due to the impact of the slow delivery of electronic chips and other products in the spring of 2021, the scheduled server received it at the end of July, four months later than the project expected. However, after receiving the device, the forcing data preparation and analysis proceed as scheduled.

| 今後の研究の推進方策 |
This year, I will finish constructing the automatic data decoding in real time to provide near-real-time flood forecasting results. Also, based on the historical flood results analysis, the return period on a global scale will be prepared. After that, the first version of high accuracy flood forecasting system is expected to be available.
