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.
A function W is a watershed of a function F if and only if W ≤ F and W preserves the contrast between the regional minima of F; where the contrast between two regional minima M 1 and M 2 is defined as the minimal altitude to which one must climb in order to go from M 1 to M 2. [7] An efficient algorithm is detailed in the paper. [8] Watershed ...
The stream order or waterbody order is a positive whole number used in geomorphology and hydrology to indicate the level of branching in a river system.. There are various approaches [1] to the topological ordering of rivers or sections of rivers based on their distance from the source ("top down" [2]) or from the confluence (the point where two rivers merge) or river mouth ("bottom up" [3 ...
ArcView, now referred to as ArcGIS for Desktop Basic, [1] is the entry-level licensing level of ArcGIS Desktop, a geographic information system software product produced by Esri. It is intended by Esri to be the logical migration path from ArcView 3.x .
GIS revolutionized curation, manipulation, and input for complex computational hydrologic models [2] [3] For surface water modeling, digital elevation model are often layered with hydrographic data in order to determine the boundaries of a watershed. [4] Understanding these boundaries is integral to understanding where precipitation runoff will ...
