Saitama University, in collaboration with the Disaster Prevention Research Institute, the National Institute of Information and Communications Technology, and the Japan Meteorological Society, signed an agreement on March 6, 2019 (the "Agreement on Collaborative Cooperation for Disaster Mitigation Utilizing MP-PAWR and Other Technologies"). This agreement aims to promote collaboration utilizing the Multi-Parameter Phased Array Weather Radar (hereinafter referred to as MP-PAWR: see photo), which was developed and installed as part of the research project "Research and Development of Heavy Rain and Tornado Prediction Technologies" under the first phase of the Strategic Innovation Creation Program focusing on "Strengthening Resilient Disaster Prevention and Mitigation Functions." The goal is to contribute to the creation of innovations in the field of meteorological disaster reduction and the establishment of a resilient society.
Recently, meteorological disasters have occurred almost every year, leading to flooding damage due to internal water overflow. Areas that experience flooding have microtopographical features. For example, around Saitama University, as shown in the diagram, natural levees have developed on both sides of the old river channel, surrounding the floodplain. By identifying areas where rainwater tends to accumulate due to such microtopography and estimating the rainfall in those areas using MP-PAWR, it is believed that it will be possible to predict flooding depth early on.
