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 Pacific Basin is bounded by the Continental divide to the east and Pacific Ocean to the west; the basin excludes the endorheic Great Basin in the west. The Great Basin has a closed loop boundary encompassing substantially all of Nevada, the western half of Utah and parts of Oregon, California, Idaho, and Wyoming.
A drainage basin's boundaries are determined by watershed delineation, a common task in environmental engineering and science. In a closed drainage basin, or endorheic basin , rather than flowing to the ocean, water converges toward the interior of the basin, known as a sink , which may be a permanent lake, a dry lake , or a point where surface ...
Also, region and subregion boundaries end at the U.S. international boundary. [6] The various subdivisions of this system are not necessarily synonymous with watersheds for a number of reasons. As one analysis put it: "The hydrologic unit framework is in fact composed mostly of watersheds and pieces of watersheds.
A drainage divide, water divide, ridgeline, [1] watershed, water parting or height of land is elevated terrain that separates neighboring drainage basins. On rugged land, the divide lies along topographical ridges , and may be in the form of a single range of hills or mountains , known as a dividing range .
Water and tracer dye may be pumped through this system to represent the flow of the simulated groundwater. Some physical aquifer models are between two and three dimensions, with simplified boundary conditions simulated using pumps and barriers. [4]
The Boundary Waters is the largest wilderness area east of the Rocky Mountains. It spans more than 1 million acres along the U.S.-Canada border and is filled with forests, glacial lakes and streams.
Watershed management is the study of the relevant characteristics of a watershed aimed at the sustainable distribution of its resources and the process of creating and implementing plans, programs and projects to sustain and enhance watershed functions that affect the plant, animal, and human communities within the watershed boundary.
