Drainage basin of the Ohio River, part of the Mississippi River drainage basin. In hydrology, the drainage basin is a logical unit of focus [clarification needed] for studying the movement of water within the hydrological cycle. The process of finding a drainage boundary is referred to as watershed delineation. Finding the area and extent of a ...
The endorheic basin that feeds water into Üüreg Lake, Mongolia NASA photo of the endorheic Tarim Basin, China. An endorheic basin (/ ˌ ɛ n d oʊ ˈ r iː. ɪ k / EN-doh-REE-ik; also endoreic basin and endorreic basin) is a drainage basin that normally retains water and allows no outflow to other external bodies of water (e.g. rivers and oceans); instead, the water drainage flows into ...
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.
Watersheds of North America are large drainage basins which drain to separate oceans, seas, gulfs, or endorheic basins. There are six generally recognized hydro-logical continental divides which divide the continent into seven principal drainage basins spanning three oceans (Arctic, Atlantic and Pacific) and one endorheic basin
It includes oceanic sea drainage basins which have hydrologically coherent areas (oceanic seas are set by IHO convention). The oceans drain approximately 83% of the land in the world. The other 17% – an area larger than the basin of the Arctic Ocean – drains to internal endorheic basins. There are also substantial areas of the world that do ...
Dendritic drainage: the Yarlung Tsangpo River, Tibet, seen from space: snow cover has melted in the valley system. In geomorphology, drainage systems, also known as river systems, are the patterns formed by the streams, rivers, and lakes in a particular drainage basin. They are governed by the topography of land, whether a particular region is ...
A drainage basin is an area of land where all surface water converges to a single point at a lower elevation. In North America, "watershed" is used for this sense, while elsewhere terms like "catchment" or "drainage area" are used. A drainage divide is the line that separates neighboring drainage basins. In English-speaking countries outside of ...
[2] [3] The land area producing runoff that drains to a common point is called a drainage basin. Runoff that occurs on the ground surface before reaching a channel can be a nonpoint source of pollution, as it can carry human-made contaminants or natural forms of pollution (such as rotting leaves).
