Greeting the readers of the channel!
Everyone knows the European country called the Netherlands. This country is located in the northern part of Western Europe. In general, it has a strategically advantageous location. In view of this, this country at one time got rich and became the center of shopping hubs and ports of Western Europe. But there are negative sides. Specific, Dutch lands suffer from frequent floods. Therefore, in this country already centuries are building a system of channels and protective structures along the coast, which protect the coast from «big water».
Perhaps you did not know, but 1/5 of the population of the Netherlands live in the territory, which is lower than the sea level. In addition, half the territory of the country is located in the territory, which is not higher than one meter above the sea level. We conclude that up to 70% of this country is in the risk area before flooding, which may arise as an exit from the banks of the Rhine River and from raising the sea water in the North Sea. But the Netherlands found a way out of this hopeless, as it would seem that positions.
In the mid-1950s. The Netherlands government began the implementation of the breakthrough project «Delta», which should have rid of the country from frequent floods from the North Sea. The system of flooding «Delta» was created mainly to protect the territories of the country that are located in the Rhine River Delta. These are the lowest provinces of this country, such as Brabant, Holland and Zealand. Accordingly, a huge number of people live on this territory.
In general, this system was built over 40 years: from 1950 to 1997. Dams, gateways and storm barriers that protect the coast were built. In general, the system includes 13 flood protection objects. Initially, I just wanted to create a freshwater lake in the place of the Rhine delta, break for this part of this Delta itself. But then assessing the general damage to the region and the country as a whole, it was decided to create a whole system of hydraulic structures from dams and gateways.
This protective system «Delta» works in such a way that it controls the sea level on the coast within the system itself and retains the Rhine Rhine Delta natural habitat. The most interesting and unusual hydraulic objects in the «Delta» are storm barriers. The most famous storm barriers is Oosterschelde and Maeslantkering. The first was opened in 1986, and the second — 1997. Storm barriers themselves 9 km long and consist of concrete piles whose weight is 18 tons each.
Between such barriers there are steel gates in a width of 45 meters. Usually these doors are open, but at the right moment, for example, with a spring flood or a strong storm, these gates are closed. Say, the same Maeslantkering barrier was created to protect against the city of Rotterdam and its designs can withstand 12 balleal storms. Special services are followed by the right work and safety of this system. Due to the fact that there is a Delta system, huge areas of fertile lands are treated in the Netherlands, and people feel in complete safety from natural cataclysms.
