In April and May this year the Rostock test dike was finished. The extensive instrumentation was installed during the summer. Over 60 tensiometers and a large number of soil moisture probes were installed and connected to a data logger. After the initial problems with turf development (nearly no precipitation during the summer 2012 postponed the germination on the wind exposed slopes and crests while on the areas at the dike toe the germination was successful) the turf is now developing well. First filling and seepage tests will follow in Autumn 2012. In Spring 2013 the overflowing experiments sould start.
