The invention relates to the field of ecology ,environmental protection and rational nature management and can be used for purification of river water, climate regulation during drought periods, contributes to the creation of a supply of fresh water for household, domestic and other needs of the population, and may also find application in the drainage and irrigation events.

Known a technique in which the shape of the distribution channel with level control of the upstream and taps in irrigation canals and waste channel at the end of the irrigation system (A.S. 1212383 published 23.02.1986 year).

However, the known method is intended for irrigation in greenhouses with a certain concentration of the nutrient solution, which complicates the method.

There is also known a method in which the form of irrigation and drainage systems, including swimming pools-drives connected (patent No. 2163068 published 18.06.1998,, IPC A01G 25/06, EV 11/00),

The known method is mnohopocetnym and complicated as educated nodes of water treatment and purification with the irrigation network and the collector.

Known technical solution is the way where they create ponds supplied with irrigation channels (patent No. 2353088 published 27.04.2009, IPC A01G 25/00).

The disadvantage of this method is that the channels formed by the slope. With the mA irrigation system is complex, and irrigation water for irrigation is only served after heating. The technical solution for the implementation of the known method is complicated, and supplied water through the ponds is not cleared.

The technical result is a simplification of the method with simultaneous purification of water.

The technical solution of the declared object is that reservoir depth of 2.5-3 m, a width of 120-150 m, length 250-280 m, the surface area of water in 3-3,5 ha form (rivers) on the banks of rivers at a distance of 150-200 m from the main channel and is connected to a channel input and drainage channels, and at the bottom of the reservoirs have a zeolite-containing clay - ility layer 10-15 cm

The method is as follows. In times of drought the presence of such reservoirs is necessary because of lack of moisture affects the vegetation, organisms and whole ecosystems. At a distance of 150-200 m from the mainstream dig the pits for reservoir depth of 2.5-3 m, a width of 120-150 m, length 250-280 m, the surface area of water in 3-3,5 hectares During the spring spill through abstracted from the river channels water enters the reservoir and filling through abstracted from the reservoir channels is returned to the river downstream approximately 2 km from the water intake. Thanks erlitou to cover the bottom, water in the reservoir is actively cleared.

Parameters depth of 2.5-3 m about snowny fact, that depth is more than 3 m will lead to stagnation of water in the deep parts of the reservoir and, consequently, to its rapid siltation and eutrophication, and at a depth less than 2 m there is a danger of drying up reservoirs, eutrophication and the eutrophication of the coastal zone during the shallow water in the hot season. The size of the reservoir width 150-280 m, length 250-280 and water surface area 3-3,5 ha provide a sufficiently powerful evaporation and hydration of atmospheric air in a radius of tens of miles on the winds. Reservoir smaller will be less effective at its intended purpose - water purification and climate regulation. Reservoir with large size creates additional difficulties for the construction, maintenance and support of the optimal environmental conditions. Thus, with increasing size of the reservoir will decrease the rate of water exchange and, consequently, activates the process of eutrophication. An area of more than 3-3,5 ha in the scarcity of fertile land, also does not meet the principles of environmental management.

Distance from shore is not less than 150 m is optimal for the preservation of floodplains and coastal areas from destruction and additional lateral erosion and not more than 200 m in order to more rapid filling and active water circulation by reducing the lengths of the inlet and outlet channels./p>

The bottom of each reservoir fill zeolite-clay - islaami layer of 10-15 cm, which are a sorbent for purification of water. Layer erlitou provides clean water from a variety of heavy metals, radionuclides, surfactants and other industrial pollutants in the river water flows.

Reservoir regulate the humidity of the atmospheric air, are the supply of fresh water for irrigation and other domestic purposes, and also clean the water from the physical, chemical and bacterial contamination.

At a distance of 150-200 m from the riverbed creates an artificial topography Cup-shaped form with course along with the deepening of 2.5-3 m, a width of 120-150 m and a length of 250-280 m, total area of 3-3,5 ha

Vicopisano clay and alluvial material is lifted and strengthened the shore. The reservoir is connected with the river channel two channels, held in 1 km upstream and 1 km downstream from the newly created reservoir. During floods through the upper inlet reservoir is filled with water and then through the lower outlet channel water returns to the river. The reservoir remains full of simultaneously running.

Erlitou floor bottom provides clean water through sorption properties, and the mirror of water in times of drought regulate moisture the content in the atmospheric air and the soil. The reservoir is also a reserve of fresh water for irrigation and other household needs of the population.

Proposed the formation of these reservoirs on the river banks of the first and second orders, in particular the tributaries of the Terek river within the foothills of the inclined plain.

Example 1. On the banks of the river Escandon on the Piedmont plain of the Western part of North Ossetia - Alania is formed by flowing water reservoir 150 m from the main channel, the depth of 2.5 m, length 250, width 120 m erlitou plated in 10 cm is Assigned to meet business needs in an ecologically clean water and regulating humidity of the coastal zone.

Example 2. On the right Bank of the river uruh at the Northern edge of the foothills sloping plain on the territory of the Kabardino-Balkarian Republic is formed by the flowing reservoir 200 m from the main channel reaches a depth of 3 m, a length of 280 m, width 150 m erlitou plated in 15 cm In order to balance the humidity of the atmospheric air in the hot period of time and meet economic needs in clean water.

Example 3. On the right Bank of the river Canbelieve in the foothills of the Eastern part of North Ossetia - Alania is formed flowing reservoir depth of 3 m, a length of 280 m, width 150 m erlitou coating the bottom 15 cm, primarily used for purification of river water from chemicalsociety, coming from the production tank OJSC "Electrozinc" - "Dog wash".

Therefore, the generated reservoir at the foothill plains facilitate purification of river water, the preservation of optimal climatic conditions zhizneobitanija humans, flora and fauna, sustainable development of coastal ecosystems and a generally flat interfluvial landscapes, at the same time serve as storehouses of fresh water for household, domestic and other needs of the population.

The method of forming reservoirs in the Piedmont plain, characterized in that the reservoir depth of 2.5-3 m, a width of 120-150 m, length 250-280 m, water surface area of 3-3,5 hectares forming rivers on the banks of rivers at a distance of 150-200 m from the main channel, connected to the channel input and drainage channels, and at the bottom of the reservoirs have a zeolite-containing clay - ility layer 10-15 cm
