  2. Watershed delineation - Wikipedia

    en.wikipedia.org/wiki/Watershed_delineation

    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.

  3. MapWindow GIS - Wikipedia

    en.wikipedia.org/wiki/MapWindow_GIS

    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.

  4. Green Kenue - Wikipedia

    en.wikipedia.org/wiki/Green_Kenue

    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 ...

  5. SMS (hydrology software) - Wikipedia

    en.wikipedia.org/wiki/SMS_(hydrology_software)

    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]

  6. SAGA GIS - Wikipedia

    en.wikipedia.org/wiki/SAGA_GIS

    System for Automated Geoscientific Analyses (SAGA GIS) is a geographic information system (GIS) computer program, used to edit spatial data.It is free and open-source software, developed originally by a small team at the Department of Physical Geography, University of Göttingen, Germany, and is now being maintained and extended by an international developer community.

  7. Hydrologic unit system (United States) - Wikipedia

    en.wikipedia.org/wiki/Hydrologic_unit_system...

    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.

  8. HEC-HMS - Wikipedia

    en.wikipedia.org/wiki/HEC-HMS

    This includes large river basin water supply and flood hydrology, and small urban or natural watershed runoff. Hydrographs produced by the program are used directly or in conjunction with other software for studies of water availability, urban drainage, flow forecasting , future urbanization impact, reservoir spillway design, flood damage ...

  9. Watershed (image processing) - Wikipedia

    en.wikipedia.org/wiki/Watershed_(image_processing)

    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]
