    en.wikipedia.org/wiki/Yamuna

    The Yamuna (pronounced [jəmʊnɑː]; IAST: Yamunā) is the second-largest tributary river of the Ganges by discharge and the longest tributary in India.Originating from the Yamunotri Glacier at a height of about 4,500 m (14,800 ft) [1] on the southwestern slopes of Bandarpunch peaks of the Lower Himalaya in Uttarakhand, it travels 1,376 kilometres (855 mi) and has a drainage system of 366,223 ...

  3. Catchment hydrology - Wikipedia

    en.wikipedia.org/wiki/Catchment_hydrology

    Catchment hydrology is the study of hydrology in drainage basins. Catchments are areas of land where runoff collects to a specific zone. This movement is caused by water moving from areas of high energy to low energy due to the influence of gravity. Catchments often do not last for long periods of time as the water evaporates, drains into the ...

    Himachal Pradesh provides water to both the Indus and Ganges basins. The drainage systems of the region are the Chenab, the Ravi, the Beas, the Satluj and the Yamuna. These rivers are perennial and are fed by snow and rainfall. They are protected by an extensive cover of natural vegetation. Beas river and mountains as seen from Van Vihar, Manali.

  5. Watershed delineation - Wikipedia

    en.wikipedia.org/wiki/Watershed_delineation

    Watershed delineation is the process of identifying the boundary of a watershed, also referred to as a catchment, drainage basin, or river basin. It is an important step in many areas of environmental science, engineering, and management, for example to study flooding, aquatic habitat, or water pollution. The activity of watershed delineation ...

  6. Chambal River - Wikipedia

    en.wikipedia.org/wiki/Chambal_River

    The Chambal River is a tributary of the Yamuna River in Central and Northern India, and thus forms part of the drainage system of the Ganges. [2] The river flows north-northeast through Madhya Pradesh, running for a time through Rajasthan, then forming the boundary between Rajasthan and Madhya Pradesh before turning southeast to join the Yamuna in Uttar Pradesh state.

  7. Drainage basin - Wikipedia

    en.wikipedia.org/wiki/Drainage_basin

    A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the drainage divide, [ 1 ] made up of a succession of elevated features, such as ridges and hills.

  8. Drainage density - Wikipedia

    en.wikipedia.org/wiki/Drainage_density

    Drainage density is a quantity used to describe physical parameters of a drainage basin. First described by Robert E. Horton, drainage density is defined as the total length of channel in a drainage basin divided by the total area, represented by the following equation: [1] The quantity represents the average length of channel per unit area of ...

  9. Runoff curve number - Wikipedia

    en.wikipedia.org/wiki/Runoff_curve_number

    Runoff curve number. The runoff curve number (also called a curve number or simply CN) is an empirical parameter used in hydrology for predicting direct runoff or infiltration from rainfall excess. [1] The curve number method was developed by the USDA Natural Resources Conservation Service, which was formerly called the Soil Conservation ...
