• Professional discharge simulations
  D8-, MD- and MDD8-algorithms to simulate discharge.


• Optional weight and seepage rasters
  Possibility to consider different amounts of precipitation and seepage.


• Detailed examination of catchments
  Outstanding functions like Flow Accumulation, Flow Maximum and Flow Change (relative changes in flow direction).


• Non-point-source and point-source simulations
  Examinations of total catchments (area-source) or single sources of pollutants (point-source).

HYDRO TOOLS is seamlessly integrated ArcView GIS and may be used for all non-commercial purposes. A lot of sample studies from different users have been made in the last years. Some are public and available in the documents section (Customer samples >>).
