Many reservoirs built in a basin’s upper and middle parts are used inefficiently. “Generally, reservoirs do not help preserve a river’s ecosystem. Since the construction of the Iriklinsky reservoir in the upper Ural, 80% of the river’s water comes from the Sakmara. In total, the Ural has 58 tributaries, the largest being the Sakmara, the Elek (or Ilek) and the Shaǵan (or Chagan). The Ural river basin is the area of land where other rivers, known as tributaries or affluents, flow and drain into the Ural, supplying its water. Thousands of hectares of land were reserved for landfill and industrial waste sites.” It includes waste from processing plants, overburden, and surrounding rocks.
The report states: “20 billion tons of industrial waste have accumulated in the Ural basin. Shortanbaev) and the Russian Federation (Yu. The report is based on material by scientists from Kazakhstan (A. There are only preliminary, very inaccurate, estimates of the volume of industrial pollution, published in 2017 in a special report of the preliminary results of research on the Ural River. And the additional environmental damage every year only aggravates the situation,” Chibilev says. We are now reaping what the twentieth century has sowed. Pollutants have accumulated in the bottom sediments and we do not know how much there are. “ No one has calculated the cost of these actions. Want more Central Asia in your inbox?

The Iriklinsky Reservoir, approximately 100km north of the Russian-Kazakh border, built for a power plant. There’s the development of unproductive, low-yielding land, now damaging the entire river basin. But when given such compliments, Chibilev says: “ When people ask me what to do, I know more about what not to do, since I can analyse the mistakes of the past.”Īnd, according to him, there were many mistakes.
He started studying the river in the 1980s and has written many scientific publications on the subject. He knows everything about it, or nearly everything. This article was originally published in Russian by the Kazakh media as part of the “Developing Journalism: Exposing Climate Change” project.Īlexander Chibilev who lives in Orenburg in Russia, is one of the world’s foremost experts on the ecology of the Ural River, which flows from the Ural Mountains in Russia to the Caspian Sea in Kazakhstan. The main reason for this is human activity, scientists say. They are watching the river grow shallower as time goes by. More than four million people in Kazakhstan and Russia live in the Ural river basin. Its entryway into the Sea of Azov, the Gulf of Taganrog, is one of the shallowest bodies of water in the world, with depths averaging a mere 3.3 ft (1 m).A disappearing river: the fate of the Ural Favoris 0 Frozen during three months of the year, it is also occasionally hampered by severe spring flooding, but also large volumes of silt that make navigation in its lower reaches treacherous because of shifting sandbanks and shallows. It is the busiest trade river of south Russia, navigable for 800 mi (1,290 km), bringing Siberian raw materials and manufactured goods from the north to the warm-water ports of the south. Known as the Tanais to ancient geographers, it was the center of Scythian culture in the centuries before and after the Christian era. Altogether, the Don basin drains 178,894 square mi (458,703 square km), most of it Russia's breadbasket (83 percent is cropland). The Don basin's largest cities are clustered below this point (Rostov, Bataysk, Novocherkassk) or along the industrial Donets basin in Ukraine (Kharkov, Lisichansk, Lugansk). The canal joins the Don in the Tsimlyanskoye Reservoir, one of Russia's numerous vast hydroelectric projects built in the Soviet era, with a large dam between the towns of Tsimlyansk and Volgodonsk.
It is at this bend where the rivers Don and Volga are joined by the Volga-Don Canal, built in 1952.
It then flows for 1,220 mi (1,950 km), first southeast to a bend a few kilometers west of Volgograd (coming within 31 mi or 50 km of the Volga River), then southwest to its mouth on the Sea of Azov. The Don rises near the city of Tula, about 125 mi (200 km) southeast of Moscow. The Don River basin also includes its most important tributary, the Donets, which flows through the northeastern corner of the UKRAINE, the most industrially active region of that country, known for its coal and production of steel and heavy manufacturing machinery. THE DON RIVER IS one of RUSSIA's major commercial rivers, which, connected to the VOLGA through the 65-mi (105-km) Volga-Don Canal, allows river traffic to sail from Russia's interior ports as far inland as MOSCOW to ports on the BLACK SEA and beyond to the MEDITERRANEAN.
