[Freegis-list] Free tools for modelling and assessment of hydrologic networks

[Rafael Koch]

Hello out there,

I would like to know if there are free tools suitable to model and assess 
hydrologic networks (topology, source analysis, query by attribute, flow 
simulation, etc.). Data storage should preferably be OGC-compliant or 
possibly made so by exporting to some geodatabase. Any ideas?

What I have by now is an ArcGIS geodatabase containing the network, complete 
with nodes and junctions. The tools should be able to make use of the data, 
be it directly or after some exporting/importing. 

This would lead to the next question: What would be the best practice to 
migrate data from ArcGIS personal database to PostGIS database?

Thank you very much in advance,
Rafael
