A hierarchical watershed transformation converts the result into a graph display (i.e. the neighbor relationships of the segmented regions are determined) and applies further watershed transformations recursively. See [18] for more details. A theory linking watershed to hierarchical segmentations has been developed in [19]
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.
MapWindow GIS and its associated MapWinGIS ActiveX Control were originally developed by Daniel P. Ames and a team of professors and students at Utah State University in 2002-2003 as part of a research project with the Idaho National Laboratory in Idaho Falls, Idaho as a GIS mapping framework for watershed modelling tools in conjunction with source water assessments conducted by the laboratory.
The Watershed Modeling System (WMS) is a proprietary water modeling software application used to develop watershed computer simulations. The software provides tools to automate various basic and advanced delineations, calculations, and modeling processes. [ 9 ]
The pieces include units that drain to segments of streams, remnant areas, noncontributing areas, and coastal or frontal units that can include multiple watersheds draining to an ocean or large lake. Hence, half or more of the hydrologic units are not watersheds as the name of the framework Watershed Boundary Dataset (WBD) implies.
