  29. 29. DSD 2019, 8/11/2019, DANUBIUS Modelling Workshop Conclusion • Danubius is a promising initiative • There is an opportunity to tackle similar problems in similar river systems • Seems to be a nice opportunity to get (EU/national) funding • Might boost river research and international cooperation • Helps to improve the understanding of the Rhine-Meuse delta • Things come together: Danubius-Rivers2Morrow-Research programs Rijkswaterstaat
