Soil and Water Assessment Tool (SWAT) is a free and open source hydrology model and GIS computer simulation sponsored by the USDA. SWAT is a well known geographic hydrological model in use by many universities and government agencies around the world, and integrates with commercial products like ArcGIS .
GIS is being used in multiple fields of aquatic science from limnology, hydrology, aquatic botany, stream ecology, oceanography and marine biology. Applications include using satellite imagery to identify, monitor and mitigate habitat loss. Imagery can also show the condition of inaccessible areas.
Geographic information systems (GISs) have become a useful and important tool in the field of hydrology to study and manage Earth's water resources.Climate change and greater demands on water resources require a more knowledgeable disposition of arguably one of our most vital resources.
Supports desktop, web, and mobile applications. In addition to spatial data editing and visualization, ArcGIS provides spatial analysis and modeling features including overlay, surface, proximity, suitability, and network analysis, as well as interpolation analysis and other geostatistical modeling techniques. Python, Web API, .NET: Proprietary.
SWAT (soil and water assessment tool) is a river basin scale model developed to quantify the impact of land management practices in large, complex watersheds.SWAT is a public domain software enabled model actively supported by the USDA Agricultural Research Service at the Blackland Research & Extension Center in Temple, Texas, USA.

ArcInfo (formerly ARC/INFO) is a full-featured geographic information system produced by Esri, and is the highest level of licensing (and therefore functionality) in the ArcGIS Desktop product line. It was originally a command-line based system. The command-line processing abilities are now available through the GUI of the ArcGIS Desktop ...
The first version of HEC-RAS was released in 1995. [5] This HEC-RAS 1.0 solves the same numerical equation of the 1968 HEC-2. Prior to the 2016 update to Version 5.0, the program was one-dimensional, meaning that there is no direct modeling of the hydraulic effect of cross section shape changes, bends, and other two- and three-dimensional ...
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.
