Aims of the projecta) An important aim is to enable research on hydrodynamic, sediment transport, morphodynamic, and ecological processes in the various reaches of the Danube River by means of adequate hydraulic laboratories that provide a significant discharge (up to 10 m³/s without pumping) and space (large scale models).b) On the basis of an improved understanding of the processes, derived from large-scale physical models in the labs, computer-based simulations should improve, leading to hybrid models. A further aim is to establish commonly agreed upon field study sites and stations along the Danube River for calibrating and validating physical and computer-based models and for developing and testing advanced river engineering measures under 1:1 conditions.c) The cooperation of research institutions and laboratories along the Danube River is essential to improving scientific progress and stimulating the transfer of information from Basic Research to the Knowledge Society.DREAM will lead to basic improvements in research infrastructure and cooperation between research institutions in the Danube basin. The two new laboratories, combined with the existing ones, offer a unique opportunity for large-scale physical laboratory investigations involving both fundamental and applied research.Description of Activities(1) Construction of two large Responsible River Modelling Centers/hydraulic engineering laboratories (>5000 l/s)(2) Cooperation of existing hydraulic engineering laboratories(3) Formation of a cluster/network of river engineering simulation tools(4) Establishment of a network of field study sites along the Danube River and tributaries(5) Construction and operation of a research vessel with diving shaft for the whole Danube(6) Establishment of a network of existing and extended Danube River Research Institutions throughout all riparian countries
