From ancient times, in Western culture and worldwide, water has been an enduring theme in the arts. Water themes (including snow and ice) flow
Sea monsters in literature often are exaggerations of naturally occurring creatures. An enormous and “hostile” giant squid became a menacing foe in Jules Verne’s 1873 classic Twenty Thousand Leagues Under the Sea. Read more
Where is the Selenga River?
The Selenga River (often called Selenge River) is a major river in Asia that forms at the confluence of the Ider and Delger Rivers in northern Mongolia. It flows northeastwards through Mongolia and Russia and forms a large delta on the southeast shoreline of Lake Baikal, the world’s largest and deepest freshwater lake. Tributaries include: Eg River, Dzhida River, Orkhon River, Khanui River, Chikoy River, Khilok River, and Uda River. The Selenga is the primary contributor of water to Lake Baikal and its tributaries drain approximately 80 percent of the lake’s watershed.
The average discharge of the Selenga River into Lake Baikal varies from 100 m3/s in winter to 1,700 m3/s during spring snow melt. Read more
A drought is a period of drier-than-normal conditions that results in water-related problems. When no rain or only a very small amount of rain falls, soils can dry out and plants can die.
When rainfall is less than normal for several weeks, months, or years, the flow of streams and rivers declines, water levels in lakes and reservoirs fall, and the depth to water in wells increases. If dry weather persists and water-supply problems develop, the dry period can become a drought. Read more
Failure to protect and invest in nature has left the world’s rivers in crisis, threatening the water supply of more than five billion people according to a new study. Pollution, dam building, agricultural runoff, conversion of wetlands, and water-works engineering have severely impacting global river systems, the first- ever health assessment of the planet’s riverine ecosystems reported in Nature last week.
‘What made our jaws drop is that some of the highest threat levels in the world are in the United States and Europe,’ says Peter McIntyre, a co-author of the report who is a zoologist at the University of Wisconsin-Madison in the U.S. Read more
PlayPumps International, a US non-profit organization, has come up with a very innovative way to help Africans obtain clean water for their families. The PlayPump is a sustainable, patented water pump that gets its power from children. The PlayPump is a merry-go-round that doubles as a water pump.
The spinning of the merry-go-round pumps clean water from underground into a 2,500 liter tank, standing seven meters above the ground. A simple tap makes it easy to draw water. All excess water is diverted from the storage tank back down into the borehole. The pump is able to produce up to 1,400 liters of water per hour at 16 rpm from a depth of 40 up to 100 meters.
Women and girls in Africa are primarily responsible for collecting enough water each day for cooking, drinking and cleaning. This often means hauling heavy water containers for many miles taking, on average, three hours a day. The weight of the water containers is equivalent to about 44 pounds (20 kg). Many young girls and women must walk as much as six miles every day to retrieve water for their families. Some have to make the trip twice. Read more
