Netherlands Centre for Coastal Research
Invitation for the 3rd Christiaan Brunings Lecture on Tuesday 16 January from 13-17 hr at Utrecht University. This year's theme is tidal channels and shoals.
- keynote lecture Dr. Andrea D'Alpaos on ebb and flood channel behaviour in the Venice bay
- lecture Dr. Bas van Maren (Deltares) on ebb and flood channels in the Eems-Dollard estuary
- Metronome tidal facility ongoing experiment and drinks
100 seats available (admission free, coffee and drinks included) for practitioners and scientists working on tidal channels and shoals. More info and registration at www.uu.nl/bruningslecture. Previous lectures are online. Also see www.uu.nl/metronome.
We invite you to submit an abstract to the session ‘Sustainable management of river deltas under pressure’ (Session GM6.6/BG7.6/HS5.17), to be held at the EGU General Assembly 2018, 8-13 April 2018, Vienna, Austria.
The aim of this session is to bring together knowledge of both natural and societal processes (inter)acting in a delta, and their impacts, which is essential to find sustainable solutions for delta management. We invite contributions to this session on (1) human-induced processes driving change in river deltas, (2) impacts of these changing conditions, and (3) optimising delta management solutions, in particular by using an interdisciplinary approach.
Please check the EGU website for more information and application. The deadline for submitting an abstract is 10 January 2018.This session is organised by Future Deltas, a research programme of Utrecht University (NL), in collaboration with the Woods Hole Oceanographic Institution (USA) and the University of Southampton (UK).
How much sediment is exchanged between North Sea and Wadden Sea and what are the dominant processes? How do bed forms in the channels and on the shoals look like and do they migrate? What is the sediment composition of channels and shoals? Where can we find worms or bivalves on the ebb-tidal delta and how abundant are they? To answer these questions, and many more, recently a unique field campaign was carried out in the Ameland tidal inlet system from the end of August till early October as part of the SEAWAD and Kustgenese 2.0 projects. In these projects NCK partners Rijkswaterstaat, Deltares, Delft University of Technology, Utrecht University and University of Twente join their forces.
To give a short overview: Five frames were deployed on the delta, each one fully equipped to measure flows, turbulence, waves, bed forms and suspended sediment size distributions and concentrations. Further, many box-cores and bed samples were taken for benthos and sediment analysis, sediment tracers were released and recovered, Jet-ski’s and Zodiacs assisted in drifter experiments, 13-hour transect measurements were done, bed levels were measured by Multibeam, and Aquadopp profilers measured flow across the tidal watersheds. In total 6 ships and over 35 people were involved. A lot of valuable data has been gathered and coming months and years the data will be analyzed.
Media attention field campaign
There was a news item on the national television (Watch from 09:48) featuring Bram van Prooijen (TUD) and Judith Litjens (RWS). Furthermore, there was an item in KRO Brandpunt, featuring Laura Brakenhoff (UU) and Judith Litjens (RWS), in which you can see the retrieval of the Aquadopp profilers.
