Final sampling and investigation of soil chemical parameters at the German DredgDikes test and pilot dikes and vegetation development

In September 2014 the final investigation for chemical soil analyses at the German test dike and pilot dike were carried out. As expected the result so far show the need for the monitoring of the salt and nutrient ions if dredged material shall be applied. The monitoring of the vegetation development shows that within one year at all different deedged materials a good turf will establish.
Dissemination of the project issues at the 8. dredging seminar in Rostock

The dredged material seminar which took place in Rostock, 24 to 25 September 2014 was again a great success. This conference is an established event and is organized by the Steinbeis Transfer Centre of Applied Landscape Planning under the auspices of the technical committee on dredged material of the HTG and the University of Rostock
Overflowing tests on the Polish DredgDikes research dike

In the fist week of September 2014 joint forces of Gdansk University of Technology and Rostock University performed one-week of overtopping experiments at the Polish DredgDikes research dike. We have studied the erosion process on a substantially different dike construction, compared to the German research dike.
Crack detection on the German DredgDikes research dike

In the week of 1 to 5 September 2014 Dr. Zielinski from Gdansk, who has been working at the Strathclyde University in Glasgow until recently and being a well-known specialist for geophysical methods to detect cracks in embankments, is performing 3D electical resistivity tomography (ERT) measurements on the German DredgDikes research dike.
Additional DredgDikes Installation Testing Field

Based on the experience from the research and pilot dikes regarding inhomogeneities of the dreged materials, the quality control using the degree of compaction is difficult. Particularly the high variation of local water contents in the installed materials are problematic. Therefore, an additional installation testing field was prepared in Rostock.
