Funnel in the Nizhny Novgorod settlement may increase, say experts

April 10, 2013. Experts do not rule out that funnel Buturlino in the village of Nizhny Novgorod region, which failed three houses will increase, according to the regional UMCHS Wednesday.

In a hole with a diameter of 85 meters, formed on Wednesday night in the village Buturlino Nizhny Novgorod Region, failed three structures — a house, cottage and an unused grain warehouse. Were evacuated 33 people, including eight children.

"According to the preliminary conclusion of experts" Protivokarstovaya and coastal protection ", the cause of failure was the karst collapse of the roof of the karst band located, approximately, at a depth of 50-60 meters from the surface of the earth," — said in a statement.

Karst holes — it collapses the upper layer of the earth into underground cavities, formed by the action of groundwater.

The governor of the Nizhny Novgorod region Valery Shantsev said that the issue could be caused by the rise of ground water due to flooding.

"There is a theory that the failure was caused by ground water that rose with the flood. If so, this is another very strong argument against the change in the level of Cheboksary reservoir. The rise of up to 68 minutes will trigger an increase in the level of this kind of phenomena, "- said the governor.

However, RusHydro assured that the Cheboksary reservoir level rise will not lead to new failures of soil in the Nizhny Novgorod region.

The situation on the spot and help

The decision of the Emergency Commission Buturlinsky area residents affected houses allocated 60,000 rubles material aid — 10,000 owners of holiday homes, 20,000 rubles — people living at home, and 10 thousand inhabitants of the three houses that are in the zone of potential expansion of the funnel.

At a distance of 90-100 meters from the edge of the crater takes stage SMAGIN-Kamenischi GR. However failure almost no impact on the operation of the railway: the movement of trains shall not be suspended, but the speed in this area is reduced to 40 kilometers per hour.

At a meeting of staff on emergency decision to enter into the settlement Buturlino state of emergency. At the site of the failure are specialists protivokarstovoy and coastal protection.

Cheboksary HPP

The rise of the Cheboksary hydroelectric power station, which is JSC "RusHydro" charted in 2020, will increase the water pressure at the station and thereby terminate its full capacity of 1.4 thousand MW in the year (to date the highest possible capacity — 800 MW). The area of land flooding will get the Nizhny Novgorod region, Mari El and Chuvashia.

At the last in September 2012 hearing of the Public Chamber of the Russian Federation government representatives of the Nizhny Novgorod region and the Republic of Mari El voted against raising the level of the Cheboksary hydroelectric power station, while the Chuvash supported the project.

Commissioning of the first hydro Cheboksary HPP was implemented with a reduced level of Cheboksary reservoir (61 meter) In 1980. In order to navigate in the spring of 1981 the level was raised to an intermediate level of 63 meters. The deadline for work on the flood zone of the reservoir to the design level of 68 meters has been planned for 1987. However, due to lack of funding and work in progress for the protection of lands and settlements, the project was suspended.
