| Outline of Final Research Achievements |
In this study, we developed a new dynamic flux system to measure and estimate evaporation flux. Secondly, the field measurements were conducted to evaluate turbulent velocity fields within urban canopy layer in a field measurement site. Lastly, we conduced both numerical and experimental studies to build datasets to evaluate rare but high-risk events indoor and outdoor areas. By developing the system of the evaporation flux using infra-red spectroscopy, we successfully determined the mass transfer coefficient from a surface behind a building obstacles. This system help determining the transfer coefficient. In addition, we also proposed evaluating methods of rate but high-risk event within an urban area using both wind-tunnel experiment and field measurement fo the turbulent flow fields within urban areas. The proposed method enables to determine the rate wind speed magnitude and frequency based on the probability density distribution.
