Real-time flood projection system to be tested in Tokyo

A team of scientists from Waseda University, the University of Tokyo, and the Remote Sensing Technology Center of Japan devised a computer system that predicts flood levels 30 minutes into the future in Tokyo’s 23 wards in real time.

The new system, called Sekine’s urban inundation Prediction System (S-uiPS), provides more accurate forecasts than currently existing ones. Waseda Professor Masato Sekine, an expert on hydraulics and river engineering whom the system is named after, hopes that the system will ease damages caused by floods.

S-uiPS is scheduled for launch on a trial basis by the end of June this year, and its stable operation is expected to be ready by the Tokyo Olympic and Paralympic Games in 2020.
