Seeking open source alternative to RivEX (add-in for ArcGIS designed to process vector river networks)

by VforVancouver   Last Updated April 15, 2019 11:22 AM

I wish to process a river network - for the assessment of hydrological potential. RivEX is one addin (not free) which could be used with ArcGIS.

Is there any alternative to this?
