Final Project Meeting on Sylt

Last week the STENCIL partners met at the Alfred Wegener Institute on Sylt for the 6th (and final) project meeting. At the meeting all partners presented their latest results and ongoing work. Additionally, we planned the joint tasks for the remaining months in order to successfully finish the project in fall.

Project meeting Sylt


We will be at this year’s EGU General Assembly in Vienna (7 – 12 April 2019) to present first results from the GWK experiments which were conducted within WA4 last year. The #FlumeFriday session (12 April, 10:45-12:30, PICO spot 1) is an interactive PICO session which allows visitors to flip through a detailed description of the experimental setup and procedure and to take a first look at the experimental results.

In addition, colleagues from AWI (WA5) will present results of their bathymetric monitoring of the sediment extraction sites in the North Sea.

Publication in Geo-Marine Letters (WA 5)

Our project partners at AWI-Sylt have published first WA 5 results from their bathymetrical surveys in the German Bight in Geo-Marine Letters:

F. Mielck, H.C. Hass, R. Michaelis, L. Sander, S. Papenmeier, K.H. Wiltshire (2019): Morphological changes due to marine aggregate extraction for beach nourishment in the German Bight (SE North Sea). Geo-Marine Lett. 39, 47–58.

Annual KueNO Conference 2018

KüNO-Jahrestagung 2018 Hannover

This year’s Annual KueNO Conference was held in Hannover on 28 – 29 August 2018. On the first day of the event results from all KueNO projects were presented to the scientific community, authorities, policy makers and funding agencies. On the second day participants were invited to discuss about the interplay of ecosystem and sediment dynamics, as well as about coastal protection measures able to support ecosystem services. KueNO joins projects for coastal and shelf research in the North Sea and the Baltic Sea which are funded by the German Federal Ministry of Education and Research (BMBF).

GWK experiments in WA 4 are finished

Last week the STENCIL partners at FZK in Hannover finished the large-scale erosion experiments in the Large Wave Flume as part of WA 4. Within the past seven weeks, unique datasets on the transport behaviour of different sand mixtures were collected using high-resolution instrumentation. In the next months the STENCIL partners will process and analyse the data, which will be used to improve transport equations and numerical models for coastal dynamics, e.g. the behaviour of sand nourishment.

GWK experiments

Preparations for large-scale GWK experiments in full swing

The preparations for the upcoming experiments in the Large Wave Flume (GWK) in Hannover are in full swing. A 30 m long test section is currently being set up in the flume and first wave runs are expected to start in early May.

Using complex instrumentation for the measurement of detailed transport processes the experiments will provide unique data for the wave-driven transport of graded sand. The data will be used to develop a sediment transport formula for the improved prediction of coastal erosion (WA 4).

UAV-based survey on Sylt

Recently Unmanned Aerial Vehicles (UAVs), i.e. drones, have become a popular tool for aerial photography. In the framework of STENCIL we are now investigating how drone surveys could be used to monitor dunes and beaches.

In September the Ludwig Franzius Institute (LuFI), together with colleagues of the Alfred Wegener Institute (AWI), used a drone to survey 70 ha of coastal area in List on Sylt. In a controlled flight path, the drone is steered over a specific area and takes aerial photographs in regular time intervals. The flight takes about 30 min and almost 900 pictures of the surveyed area are saved. Afterwards the pictures are assembled to create a first 3D model of the beach showing the topography of the area.

In the next step the model will be calibrated and validated. GPS data will be linked to the model and used to complete any blank spots. Supported by the GPS data, the model can then be used to determine the volume of the dunes along the surveyed stretch of coastline.

The first preliminary results show that a UAV-based survey is a promising approach for the future monitoring of beach nourishments and their surroundings. The usage of drones is a simple, cheap and environmentally friendly method to survey the topography of a beach. Conducted in regular time intervals, the quick and simple method can help to identify erosion and to balance the sediment loss by nourishment. However, further investigations of the List model and other survey sites are necessary.

Annual KueNO conference

On 11-12 October 2017 STENCIL was presented at the annual conference of the German „KueNO“ organization for coastal and shelf research in the North Sea and the Baltic Sea. STENCIL is one of twelve KueNO projects which are currently funded by the German Federal Ministry of Education and Research (BMBF). The conference provided opportunities to exchange results and ideas with the other KueNO members, the German coastal authorities, BMBF representatives and interested companies. A short report in German can be found on the BMBF’s website. The presentation about STENCIL as well as a poster showing some preliminary results of WA 5 have been published on the website of KueNO.
