Ubiquitous monitoring system of rivers and dangerous from the point of view of flood areas be created in Russia to prevent the catastrophic consequences of emergency situations such as occurred in the Kuban region, said head of the Department of Land Hydrology geographical Faculty Nicholas Alexis.
Also, be aware of the engineering works on rivers to create reservoirs, where they need to devise a system of water drainage from settlements, the scientist noted in an interview with RIA Novosti.
"The main thing — to create a system of observations of rivers and dangerous areas," — said Alexis.
According to him, it is necessary to periodically monitor how the cross-section of a hazard in terms of the flood of the river in its valley for a certain period of time.
"A lot depends on whether the river bed is ready to take this flow of water without its publication in low-lying areas of the river valley, in particular understand," — said the scientist.
"These are real events, but it should be allocated funds, identify the most dangerous areas, where the future direction would be ready to receive large amounts of water," — said Alexis. We can not expect that someone will predict loss in a particular area record-high rainfall, he said.
"But if we see that the cross section is reduced, it is necessary to strengthen the direction that it be done", — said the head of the department.
According to Alexis, the second method — the creation of structures along the coast, which prevent the emergence of water on the floodplain.
"But the potential of this method is not infinite — Nobody will build ten-dam on the river banks, because the result will disappear … the very possibility of the use of water resources," — said the scientist.
Attention to bridges and forests
The third way to prevent emergencies — a careful analysis of the situation with the construction of engineering structures in flood plains and on their shores.
"Unfortunately, the practice of building cheaper clicks engineering facilities across the river suggests that part of the space within the valley, which previously could take the river is blocked by deaf mounds, and the transition is over the river. As a result, not only the capacity of the channel, but the channel and floodplain reduced, leading to increased levels of water "- complained Alexis.
He also noted the important role of water reservoirs to prevent disaster.
"For those (potentially dangerous in terms of floods) of rivers, where there is no water reservoirs, to think, to create them for flow regulation," — continued the scientist.
According to him, if it were not Neberdzhaevskogo reservoir, the effects of flooding for the Crimean would be even harder. "But Neberdzhaevskoe reservoir does not meet modern concepts of structures of this type", — said the head of the department.
Alexis said that it is important to watch and state forests in the flood areas.
"Mastered space, reduced forest roads are being built — it leads to the fact that water somewhere where previously could have accumulated, and now does not accumulate and rapidly enters the river system, and as a result there is a possibility for a more rapid rise of the water level," — said he said.
Finally, if next to the river, there are objects that require special attention, especially the settlements need to think in advance, is it possible to divert water elsewhere, said Alexis.
"As an example — in the Yellow River in China at a flow rate of 10 cubic meters per second to create a special place for the discharge of water (if necessary) are exempt passes to a special gateway, and the water is discharged there," — he said.
"Each of the options has its pros and cons, so for a single object to be developed its own system of measures to reduce the probability of a dangerous development of the situation," — concluded Alexis.
"In the country there are water management, which is a division of the Federal Agency of Water Resources, and each control all the" pain points "know" — said Alexis.
"I recently analyzed the situation in the country regarding the flood of 2010. As part of this work was to define a region with the most damage, where floods occur more often — it Rostov, Krasnodar, Stavropol region, the North Caucasus," — said the scientist.
According to him, a piece of flood damage happens and within the Middle Volga, and the Great Ustyug on the Northern Dvina, serious problems in the Far East, in the Amur basin.
"But there are completely different reasons," — said Alexis, adding that much depends on the time of year.
Krymsk: versions emergency protective measures for the future
Immediately after the flooding of the Kuban was born Krymsk version of a breakthrough or emergency descent during a downpour Neberdzhaevskogo reservoir located above the city. According to some environmentalists and local residents, the giant wave could occur by itself, but was caused by problems in the system of exploitation of the reservoir. Since were also flooded Novorossiysk and Gelendzhik, then with Neberdzhaevskim suspect was the whole system of Kuban reservoirs.
However, after examining themselves environmentalists Neberdzhaevskogo reservoir, came to the conclusion that there was no breakthrough. Ekspertyotvergli and version of the mash in the form of a road bridge, into which a supposedly huddled debris carried in a stream of water, formed a kind of dam, which eventually burst, and multimeter waves struck the accumulated water Krymsk.
End the matter put the head of the Federal Agency for Water Resources Marina Seliverstova. The outcome of the Commission departments, she said that the reservoir, or other objects of water-economic complex did not cause the catastrophic consequences of the natural flooding in the Kuban. Furthermore, as specified Seliverstova, waters collected a large amount of water and soften the blow.
Experts agree on one thing — action is needed to protect Krymsk from such devastation. Thus, the expedition of scientists hydrologists plans on Saturday to begin reconstruction of the flood in the Kuban. The conclusions of the scientific group should form the basis for future decisions to protect residents. Among the options considered engineering protection of territories, as well as the release filled river valley, which today was occupied buildings.
Flooding on the night of July 7 sank 7.2 thousand houses in the three cities (Gelendzhik, Crimea, Novorossiysk) and a number of villages of the Krasnodar Territory. Violated the electrical, gas and water supply, road and rail traffic. Killed more than 170 people. Most of the victims were in Krymsk, when there was the biggest shock element.
