Abstract
Hydrological meta-modeling for watershed management has been proposed. A physically-distributed, surface and subsurface fully-coupled fluid flow code GETFLOWS was used to derive the metamodel. The metamodel has been well-trained the mutual interaction between surface water and subsurface water flow, and has predicted the water resources indicator without time-intensive computation. The adequate accuracy of the computed indicators for an actual river basin has been attained by using the metamodel. We proposed here a combined-application of the surface and subsurface coupled fluid-flow modeling and the meta-modeling concept to the practical water resources management.
