"Glowa-Danube: Integrative Modelling of Global Change Effects on the Water Cycle - the Groundwater Perspective"

GLOWA (Global Change of the Water Cycle,, funded by the German Ministry of Research and Education, addresses the manifold consequences of Global Change on regional water resources in a variety of medium sized watersheds. The Upper Danube Basin (A ~ 77.000 km²) represents a mountain-foreland situation in the temperate mid-latitudes. The major goal of “GLOWA-Danube” is the development of new water resource management modelling technologies integrating natural and socio-economic sciences. A university-based distributed network of experts are developing and utilizing the Decision Support System DANUBIA, a coupled system that is based on reuseable, refineable, well-documented sub-models. DANUBIA and its sub-components are object-oriented, spatially distributed, raster-based and developed using the Unified Modelling Language UML and Java. This paper describes the framework of GLOWA-Danube and the integrated model DANUBIA with a focus on the two models developed by the University of Stuttgart.
