[Freegis-list] GIS Hydrology Software

[Chris Ryan]

Hi,

I thought some people on this list may be interested in some free
software that I have been developing.  It is a standalone GIS package
tailored towards hydrologic applications.

Briefly, CatchmentSIM is based on a raster DEM which can be imported, or
interpolated from contours and streams.  The model delineates watersheds
and calculates hydrologic parameters using more accurate (vector based)
algorithms than the traditional D8 method.  

Analysis tools include vector stream network generation and analysis
with Strahler / Horton stream ordering, bifurcation charting etc.  The
software also includes a macro language that allows customised export
for tight coupling with other models.  For example, a user can setup the
model to automatically create input files for other software.

More information, software downloads and a quick tutorial can be found
at www.uow.edu.au/~cjr03
