Abstract
A prospective review on the contribution of hydraulics and fluid mechanics to various problems of global environment engineering is reported on behalf of The Committee of Hydraulics, JSCE. In the Committee, the Association for Global Environmental Hydraulic Research (AGEHR) has been organized to enhance researches of such important problems in hydraulic engineering. It is addressed strongly in this review that new research projects are nesessary to investigate the interaction mechanism between air and water surfaces in various water enviroment engineering.
