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 Pfafstetter Coding System is a hierarchical method of hydrologically coding river basins.It was developed by the Brazilian engineer Otto Pfafstetter [] in 1989. [1] It is designed such that topological information is embedded in the code, which makes it easy to determine whether an event in one river basin will affect another by direct examination of their codes.
Moose's mom posted a video that's only about 12 seconds long, but it's really funny to watch. Moose found a wheelbarrow full of water out in his backyard and decided to hop on in and enjoy it.
The watershed basin and stream delineation tool uses either the Jenson or At Search algorithm and allows for artificial diversions. A suite of sophisticated basin metrics and digital elevation map analysis tools is provided, including statistical and analysis functions such as temporal min, max, mean, standard deviation, slope and curvature ...
