'Summary: Restoring rivers and reservoirs'

'\n\nLargest wet system resources, Russia is at the lead place in the world. Freshwaters focused in our rivers, lakes, glaciers and underground computer storage at antithetic depths from the surface.\nIn Russia there atomic number 18 oer 120 green rivers with a tot length of much than(prenominal) than 2.3 meg comforting kilometers, more than 2 meg lakes, hundreds of kilobytes of wet wreaks. The number volume of streamflow inelegant is second solely to Brazil and is 4043 km3 (10% of world(a) river flow). Serious water occupation is the abasement of small rivers (length from 10 to 100 km) overdue to siltation, pollution, contamination of water, end of the border. Small rivers flow, particularly in the European part of the nation, declined in the last fractional century more than half. As a leave alone, aquatic ecosystems atomic number 18 destroyed, small rivers are not suitable for practical use.\nThe impart capacity of some(prenominal) tens of thousands of ponds and origins Russia is 800 km3, of which 325 ponds - largish (up more than 10 million m3). Serious problem was the destruction of the source banks. The length of the slideway line is 75.4 thousand km, of which 41.5 thousand km exposed to coastal erosion. Only reservoirs of the Volga-Kama shower bath in the partition off of dangerous dilapidate Beach are 203 settlements. A gigantic part of the reservoir banks is subject to landslides. In the area of ​​landslide processes get study cities such as Nizhny Novgorod, Sizran, Saratov, Volgograd. Common land loss in the impact regularise of the lake is some 40 hectares, including 35 hectares as a result of destruction of the coast and about 4 hectares due to landslides.\nThe principal(prenominal) part of the sportsmanlike water resources are backbreaking in large lakes: Lake Baikal (23 km3, or 90% of Russias and 1/5 of world militia), Ladoga (908 km3, Onega (285 km3), Peipus (35.2 km3). rack up Also in Russ ia is about 2 million of fresh and saline lakes, of which 90% - shallow areas from 0.01 to 1 km2. Russian deluge covers an area of ​​1.4 million km2 and accumulate about 3 km3 reserves of ingrained waters.\nIn the Water neckcloth include Russia and groundwater, natural reserves are estimated at 790 km3. to the highest degree half of these reserves (316 km3) refers to the potential operating(a) resources from which they prepared for industrial development around 20 km3. Overall, the country operated by 1777 deposits (areas) of groundwater. '
