On the 9th of March, NCK and NCR jointly organise a symposium on 'Sediment management in deltas' in Vlaardingen. River to the coastal sea sediment continua are disturbed, globally. Several river-sea-systems are short of sediment mostly due to damming. This causes dramatic impacts such as drowning deltas. Scientists and stakeholders should team-up urgently in research and innovation to find solutions. This symposium addresses the status in the Rhine/Meuse – North Sea system. Furthermore, the DANUBIUS-RI research infrastructure (RI) is presented as disturbed sediment continua may become a key research topic in this RI. The symposium also aims to gain support and ingredients for drafting of a sediment continuum call text to promote as topic under EC FP9, i.e. the follow-up of Horizon 2020.
