In the first two project phases of GLOWA-Danube the integrative decision support system DANUBIA was successfully implemented, sectoral as well as integrative validated and first scenario calculations were performed. These show that the coupling of the submodels was successful and DANUBIA can be used for relevant global change question.

The third phase of funding was aimed to use the entire system DANUBIA to simulate together with stakeholders (decision makers from policy, economy and administration) integrated scenarios of future change in the hydrological cycle, water consumption and water availability in the Upper Danube basin for evaluation, for scientifically interpretation, and finally for the discussion in an iterative Stakeholders dialogue. Major points of interaction were thus between DANUBIA and the stakeholders, the responsible authority for and affected by the regional water management.

The scenario results for the period 2011 to 2060 showed e.g. that the result of climate change expected slight decrease in rainfall and increased evaporation due to the temperature rise simultaneously with the reduction of snow storage in the Alps lead to a pronounced forward displacement of the seasonal availability of water from summer to spring and to a decrease in the low flow discharges of the main rivers in the Upper Danube catchment. The reduction of hydropower production and restrictions on navigation in low water periods are inter alia the consequences.

DANUBIA is at the end of the 3rd project phase "open source" and is therefore available for further use and development. Moreover DANUBIA is in principle transferable to other mountain regions with similar complex structures.
