[GRASSLIST:9627] Re: water resource management with GRASS & RDBMS

[Massimiliano Cannata]

Hello, I've just used some functions of the ArcHydroTools....
Then I just developed a DB structure for online-realtime stationa and a 
Rainfall-runoff Distributed Model within GRASS (embedded)....
I think that your idea is really nice and helpfull.
I also think that it could be ported in the OpenSource by using GRASS 
data structure!!!
I also believe that I could adjust my model to get starting data and 
pre-processing from this new data structure,
in order to build an hydrologic GRASS application structure...

I used the perfix h.modulename for my new developed command.
This could be an idea....

currently my model name is HydroFOSS... so OpenHydro I think is free :-)

Let me know your impression.

Have a nice holyday.
