Hvide Sande, Denmark

In half of the 11 km test area Ecobeach drainage tubes are installed (a  4.7 km section and a small 0.9 km section). According to statistical analyses no significant effect on the beach volume was measured, however, in the end of 2009 the mean diameter of the sediment within the Ecobeach sections was significantly larger than within the reference areas.
