Research Interests
In our laboratory of sanitary engineering, the computer applications to water-works, sewage-works and studying with the methods of systems analysis and applied mathematics, and also the experiments in a laboratory and the field surveys are assisted. Our subject is a practical study for an ideal future of the urban environment.
Nowadays, a lots of environmental problems in the cities are very complicated, and such problems are difficult to solve only on a viewpoint of civil engineering, therefore we must consider them on the economical and sociological viewpoints and etc. The purpose of our study is to find the compromised better solution for the problems in the fields of water and wastewater engineering and also municipal solid wastes engineering.
