Between coast of the river and these two islets on all length of a dam have established 65 huge ferro-concrete columns, everyone in weight of 18 thousand tons. As force of underwater pressure during a storm can reach 7 tons on square metre, the bases of these columns, as well as thresholds of sluices, are designed in the form of filters. Preliminary the river bed part where the dam (and it is 7 square kilometres) was established, for displacement prevention was vystlana specially made filtering floor-mats filled with sand and gravel (a thickness of a floor-mat - 42 centimetres, and weight - 5600 tons). Each ferro-concrete column fastened on two such floor-mats an embankment from stones, boulders and boulders, and them it was required neither much nor few 5 million tons, and all of them have been delivered from Sweden and Finland. Thus floor-mats kept within so that the backlash between them did not exceed two centimetres. On columns steel gate, or as them still name, boards-zaslonki, their only 62 were suspended. These are monoliths in weight of 500 tons everyone and length 42 metres, height 12 and thickness of 0,55 metres. These gidravlicheski operated gate operate independently, they can be lifted or lowered in full or in part depending on weather conditions. During a collar storm are tightly closed, and terrible breakers of terrible destructive force fight about them and are rolled away back, not reaching country coast. In good weather of a collar are opened and pass sea inflow in the gulf fenced off by a dam, not giving water to be freshened and blossom and keeping thereby sea flora and fauna. From above on a dam the motorway connecting both coast is laid chetyrehrjadnaja.

This dam and Zejlandbrjug now the most impressing tourist objects of Zealand, worthy not only attention, but also admiration.

Coming to get acquainted with the well-known hydraulic engineering constructions necessarily visit Middelburg - the centre of a province Zealand, one of the most ancient cities in territory of the present Netherlands. It is much more senior even Amsterdam.
