Since 22 May 2013 the three Rostock test dike polders are filled alternately to investigate the infiltration process and the amount of seepage water that is collected on the inner slope and in the dike core respectively. Figure 1 shows the general setup of the test dike polder system while figure 2 shows a general setup of the instrumentation inside the cross-sections where the seepage is recorded. The polders will all be filled at least three times for every test campaign. As an example figures 3 and 4 show the filled polder 2 and its rather brown grass cover when emptied after 10 days which is due to fines sedimentation from the brackish water used in the experiment. Figure 5 shows the filled polder 3 while testing the closure of the overflowing section.

Results will be published here as well as in the guideline documents.
