Finding solutions to support your decision making in water related issues.
The brief overview of national-scale water circulation model of Japan.
The newly developing world terrestrial fluid-flow models.

GETFLOWS is a three-dimensional finite difference, multi-phase & multi-component fluid-flow simulator with the fully-coupled surface and subsurface fluid-flow. GETFLOWS provides fast & robust numerical solutions to simulate all types of terrestrial fluid-flow system together with the distributed setting of precipitation, evapotranspiration, hydro-geology, land use, water use and so on.
