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 list of drainage basins by area identifies basins (also known as "catchments" or, in North American usage, "watersheds"), sorted by area, which drain to oceans, mediterranean seas, rivers, lakes and other water bodies.
Watersheds as optimal spanning forest have been introduced by Jean Cousty et al. [12] They establish the consistency of these watersheds: they can be equivalently defined by their “catchment basins” (through a steepest descent property) or by the “dividing lines” separating these catchment basins (through the drop of water principle ...
Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, [3] [4] and impluvium. [ 5 ] [ 6 ] [ 7 ] In North America, they are commonly called a watershed , though in other English-speaking places, " watershed " is used only in its original sense, that of the drainage divide line.
Major drainage divides (yellow and red ridgelines [1]) and drainage basins (green regions) in Europe. A drainage divide, water divide, ridgeline, [1] watershed, water parting or height of land is elevated terrain that separates neighboring drainage basins.
Catchment zone in Nattai, Australia containing drinking water. 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.
This is a list of river catchment areas, also known as drainage basins, in Indonesia.. Based on the National River Basin Classification map, Indonesia has a total of 42,210 river basins organized as a basis for determining watershed management policies.
