RiverTools is an intuitive GIS program for Windows which provides features for analysis and visualization of digital terrain, watersheds and river networks. One of its main advantages is the capability to extract drainage patterns and process hydrological data from large DEMs.

Main capabilities

Using this software, you can conduct comprehensive analysis of watersheds, sub basins and river networks in a short amount of time. It delivers accurate measurement of characteristics like upstream area, channel lengths, elevation drops, slope and curvature with the help of the Earth ellipsoid model.

It is possible to delineate catchment boundaries and calculate multiple basin and subbasin parameters. There is support for importing and exporting data from other GIS applications. You can also interact with remote sensing, image processing systems.

GUI extension

By default the utility relies on a user-friendly graphical interface for access to its capabilities. This includes powerful mosaicking, visualization and analysis routines. It is worth mentioning that you can also use the tool together with IDL, an easy to use programming language.

Please note that the solution is distributed on a paid basis. However, you have the option to request a demo by sending your contact details to the developers. You may also try a free ArcGIS extension called ArcSWAT.
