Method for improving the ecological situation in the reservoirs

 

(57) Abstract:

The invention relates to the geological ways to create a landscape of Islands on the water surface of the reservoir formed by the construction of hydroelectric power plants. Method for improving the ecological situation in the reservoirs is that on both sides of the old riverbed create Islands of artificial origin. The invention allows to preserve the coastline, to increase the number of fish spawning grounds, to clear old channel of the river from ziliniana, to create conditions for hunting and conservation of the farms.

The invention relates to the geological ways to create a landscape of Islands on the water surface of the reservoir formed by the construction of hydroelectric power plants.

There is a method of nanyuki Islands from U.S. patent 3803852 from 16.04.1974, This method also allows for consolidation of alluvial soil to use plants. Under subtropical conditions of the U.S. this method can be quite effective, as there are daily gains some plants reaches 30 see our conditions of continental climate such plants, there is no such specii the reservoir.

The problem is solved in that way improve the ecological situation in the reservoirs according to the invention on both sides of the old riverbed create Islands of artificial origin.

On both sides of the old bed of the river, flooded by the reservoir, washes up the archipelago of Islands, which is the main reinforcing factor preventing erosion of island coasts.

Because the old riverbed removed from the shores of the reservoir, even at low wind there is a strong excitement. Therefore, such arrangement of the Islands creates artificial barriers for excitement, which will contribute to the preservation of the coastline. The result will be reduced or completely eliminated the need for shore protection works, the banks will be self-reinforcing due to the appearance in them of riparian vegetation.

Also these Islands may be seeded grasses and drivecontroller plants. As a result of these actions throughout the reservoir appears ecologicaly basis.

This island's location also allows you to increase the length of the coastline that will lead to the emergence of a large number of new NARES is it for hunting and conservation of the farms.

Newly formed Islands with the adjacent shallow waters lowland reservoirs will perform important ecological functions as the reserves of the gene pool of flora and fauna of the former river valleys, as generators of biological resources, as sanitizing factor of the aquatic environment.

The location of the Islands on both sides of the old riverbed allows you to create a natural barrier for the anthropogenic impact on ecosystems reservoirs, and will inevitably lead to the clearing of the old river channel from silting up.

Thus, there will be an inevitable improvement of the ecological situation on the reservoir, which is the main aim of the invention.

For carrying out this invention, there are no technical problems. Inwash of Islands can be made earthen shell and gruntovalnoy equipment: bulldozers, graders, etc.

Method for improving the ecological situation in the reservoir, characterized in that on both sides of the old riverbed create Islands of artificial origin.
