Anthropogenic activities also include discrete elements like the use of fire, domestication of plants and animals, soil development, the establishment of settlements and irrigation. [3] River ecosystems have been transformed downstream from the point of pollution.
The nearly 3 million rivers that weave across the world are experiencing rapid and surprising changes, with potentially drastic implications for everything from drinking water supplies to flood ...
An irrigation scheme often draws water from the river and distributes it over the irrigated area. As a hydrological result it is found that: the downstream river discharge is reduced; the evaporation in the scheme is increased; the groundwater recharge in the scheme is increased; the level of the water table rises; the drainage flow is increased.
Second-longest river in China and the sixth-longest river system on Earth. Birthplace of ancient Chinese civilization. [96] 4.29 billion tons of waste and sewage discharged in 2007 alone, mainly from urban factories and manufacturing facilities. [97] One-third of the river's course rendered unusable even for agricultural or industrial use. [98 ...
The column of water in a large and deep artificial lake alters in-situ stress along an existing fault or fracture. In these reservoirs, the weight of the water column can significantly change the stress on an underlying fault or fracture by increasing the total stress through direct loading, or decreasing the effective stress through the increased pore water pressure.
Environmental impact of fracking in the United States has been an issue of public concern, and includes the contamination of ground and surface water, methane emissions, [1] air pollution, migration of gases and fracking chemicals and radionuclides to the surface, the potential mishandling of solid waste, drill cuttings, increased seismicity and associated effects on human and ecosystem health.
World leaders are meeting in Paris this month in what amounts to a last-ditch effort to avert the worst ravages of climate change. Climatologists now say that the best case scenario — assuming immediate and dramatic emissions curbs — is that planetary surface temperatures will increase by at least 2 degrees Celsius in the coming decades.
Many of us know the big names in the high-end-design space, like Louis Vuitton and Gucci — but just knowing the brands isn't enough to build a fashionable wardrobe.
