  2. Stream - Wikipedia

    en.wikipedia.org/wiki/Stream

    Australian creek, low in the dry season, carrying little water. The energetic flow of the stream had, in flood, moved finer sediment further downstream. There is a pool to lower right and a riffle to upper left of the photograph. A small, narrow stream flowing down a tiny dell in Pennsylvania.

  3. Streamflow - Wikipedia

    en.wikipedia.org/wiki/Streamflow

    Water flowing in channels comes from surface runoff from adjacent hillslopes, from groundwater flow out of the ground, and from water discharged from pipes. The discharge of water flowing in a channel is measured using stream gauges or can be estimated by the Manning equation. The record of flow over time is called a hydrograph.

  4. Current (hydrology) - Wikipedia

    en.wikipedia.org/wiki/Current_(hydrology)

    The water in this stream forms varying currents as it makes its way downhill. In hydrology, a current in a water body is the flow of water in any one particular direction. The current varies spatially as well as temporally, dependent upon the flow volume of water, stream gradient, and channel geometry.

  5. River - Wikipedia

    en.wikipedia.org/wiki/River

    A river is a natural flow of freshwater that flows on or through land towards another body of water downhill. [1] This flow can be into a lake, an ocean, or another river. [1] 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]

  6. River ecosystem - Wikipedia

    en.wikipedia.org/wiki/River_ecosystem

    The "flow regime" of a river or stream includes the general patterns of discharge over annual or decadal time scales, and may capture seasonal changes in flow. [7] [8] While water flow is strongly determined by slope, flowing waters can alter the general shape or direction of the stream bed, a characteristic also known as geomorphology. The ...

  8. List of rivers by discharge - Wikipedia

    en.wikipedia.org/wiki/List_of_rivers_by_discharge

    The average flow rate at the mouth of the Amazon is sufficient to fill more than 83 such pools each second. The estimated global total for all rivers is 1.2 × 10 6 m 3 /s (43 million cu ft/s), [1] of which the Amazon would be approximately 18%.

  9. Hydrology - Wikipedia

    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 ...
