  2. River morphology - Wikipedia

    en.wikipedia.org/wiki/River_morphology

    The terms river morphology and its synonym stream morphology are used to describe the shapes of river channels and how they change in shape and direction over time. The morphology of a river channel is a function of a number of processes and environmental conditions, including the composition and erodibility of the bed and banks (e.g., sand, clay, bedrock); erosion comes from the power and ...

  3. River - Wikipedia

    en.wikipedia.org/wiki/River

    A stream refers to water that flows in a natural channel, a geographic feature that can contain flowing water. [2] A stream may also be referred to as a watercourse. [2] The study of the movement of water as it occurs on Earth is called hydrology, and their effect on the landscape is covered by geomorphology. [2]

  4. River ecosystem - Wikipedia

    en.wikipedia.org/wiki/River_ecosystem

    Water flow can vary between systems, ranging from torrential rapids to slow backwaters that almost seem like lentic systems. The speed or velocity of the water flow of the water column can also vary within a system and is subject to chaotic turbulence, though water velocity tends to be highest in the middle part of the stream channel (known as ...

    Rain falling over a drainage basin in Scotland.Understanding the cycling of water into, through, and out of catchments is a key element of hydrology. Hydrology (from Ancient Greek ὕδωρ (húdōr) 'water' and -λογία () 'study of') is the scientific study of the movement, distribution, and management of water on Earth and other planets, including the water cycle, water resources, and ...

  6. Water cycle - Wikipedia

    en.wikipedia.org/wiki/Water_cycle

    The diagram also shows how human water use impacts where water is stored and how it moves. [1] The water cycle (or hydrologic cycle or hydrological cycle) is a biogeochemical cycle that involves the continuous movement of water on, above and below the surface of the Earth. The mass of water on Earth remains fairly constant over time.

    The non-stop circulation of water on, above, and below Earth's surface. At different times during the cycle, water changes between its different states: liquid, vapor and ice. Also called hydrologic cycle. water pollution water stagnation water vapor The gaseous state of water. watershed

  8. Historical ecology - Wikipedia

    en.wikipedia.org/wiki/Historical_ecology

    Historical ecology can use archaeological sites within this setting to study past successes and failures of indigenous peoples. The use of swidden fires in Laos is an example of historical ecology as used by current land managers in policy-making. Swidden fires were originally considered a source of habitat degradation.

  9. Atmospheric river - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_river

    Water vapor imagery of the eastern Pacific Ocean from the GOES 11 satellite, showing a large atmospheric river aimed across California in December 2010. This particularly intense storm system produced as much as 26 in (660 mm) of precipitation in California and up to 17 ft (5.2 m) of snowfall in the Sierra Nevada during December 17–22, 2010.
