[1] Research on the deployment of mathematical optimization methods in flood forecasting models
Joint research for which PWRI publicly solicited partners, and for which Fujitsu Laboratories applied and was accepted. PWRI provided the flood forecasting simulation technology, as well as a simulator and data, and Fujitsu Laboratories provided mathematical optimization technology.
[2] Nash-Sutcliffe model efficiency coefficient
A coefficient that assesses how well calculated values from a simulation model match observed measurements.
Nash-Sutcliffe efficiency coefficient = 1 - (residual variance between predicted and observed values) / variance distribution of observed values
[3] Integrated Flood Analysis System (IFAS)
An integrated analysis system for flood forecasting simulations developed and publicly released by PWRI: http://www.icharm.pwri.go.jp/research/ifas/
Public Works Research Institute accurately identifies social requirements, the people's needs and international needs and, by producing quality research results, aims to return benefits of its research results to society. In order to attain those achievements, the research departments of four institutions, Tsukuba Central Research Institute, Civil Engineering Research Institute for Cold Region, International Center for Water Hazard and Risk Management and Center for Advanced Engineering Structural Assessment and Research, implement research on prevention and reduction of natural disasters, improvement of living environment, advanced social capital stock management, measures regarding global environment issues such as energy/ resource saving, development of social capital suitable for the snow piling cold climate, advanced research and development such as new materials/ new construction methods for development of Hokkaido's agricultural and fisheries foundation and research and development in basic areas such as phenomenon/ mechanism analysis and general technologies that forms the foundation of the entire public works technologies.
