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.
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.
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 ...
It investigated 1,052 sampling sites along 258 rivers in 104 countries, representing the river pollution of 470 million people. It found that "the most contaminated sites were in low- to middle-income countries and were associated with areas with poor wastewater and waste management infrastructure and pharmaceutical manufacturing " and lists ...
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.
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 ...
Anthropogenic influences on river systems. [46] Examples are mainly from settings with a modest technological influence, especially in the period of about 10,000 to 4000 cal yr BP. Humans exert a geomorphic force that now rivals that of the natural Earth.
