A joint team from the University of Tokyo and Waseda University has developed a real time flood projection simulator. They team claims their new model is able to more accurately predicted flooding compared to previous models. The Beta phase of the new model will be launched in Tokyo’s 23 wards with the hope of having full flood prediction operations up and running before the Olympics next year.

The new system called S-uiPS, short of “Sekine’s urban inundation system” uses data of sewage systems, street structures and connectivity to rivers in addition to rainfall projection data from the Meteorological Agency and transport authority to predict flooding in real time. The real-time predictions can help municipal authorities make important life saving decisions.
