WATER RESOURCES OF MONGOLIA
Despite the presence of the Gobi desert, Mongolia is rich in rivers and lakes. The total water resources of Mongolia is approximately 34 billion cubic metres. Most of which was fresh water. 51% of the volume of water discharged into the basin of the Northern Arctic ocean, 12% in the Pacific basin and the remaining 37% in the Central Asian basin (which has no runoff into the ocean).There are almost 4,000 rivers, the total length of which is more than 40,390 miles (65,000 km).
The rivers of Mongolia are born in the mountains. Most of them are the upper streams of the great rivers of Siberia and the Far East, carrying their water into the Arctic and Pacific oceans. The largest rivers of the country is the Selenga (in Mongolia boundaries — 600 km), the Kerulen (1100 km), Onon river (300 km), the Halhin-Gol, etc. comdo The deepest — the Selenga. It originates with one of the ridges of the Khangai, receives several large tributaries of the Orkhon, Hanuj-goal, the Chulutyn-Gol, Delger-Muren, etc. the Speed of its flow is from 1.5 to 3 m per second. In any weather its a quick cold water current in a clayey-sandy banks, and therefore always muddy, are dark gray. The Selenga river is frozen for six months, the average thickness of ice from 1 to 1.5 m. Has two floods in a year: spring (snowmelt) and summer (rainfall). The average depth at the lowest water level is not less than 2 m. after Leaving the confines of Mongolia, the Selenge river flows through the territory of Buryatia and flows into the Baikal.
River in Western and South-Western parts of the country, flowing down from the mountains, and get into intermountain basins, and release into the ocean do not have and usually end up in one of the lakes.
In Mongolia there are over a thousand permanent lakes and much more time, formed in the rains and disappearing in times of drought. In the early period a considerable part of the territory of Mongolia was an inland sea, divided later into several large ponds. The current lake — what’s left of them. The largest of them are located in the Great lakes basin in the North-West of the country — UBS-Nur, Khara-Us-Nur, Hirgis-Nur, their depth does not exceed a few meters. In the East there is lake Buir-Nur and huh-Nur. In giant tectonic depression in the North of the Khangai is a lake Khubsugul (depth to 238 m), similar to Baikal the water of relict flora and fauna.
