[GRASSLIST:9625] water resource management with GRASS & RDBMS

[M S]

As some of you may or may not know.  that OTHER software company is trying
to establish their Geodatabase data model as a "GIS standard" (at least this
is the trend in the US from what I'm seeing).  I havent been impressed or
enthused about it at all.  This second generation, "windows only" software
(arcmap) by that other company has had many, many shortcomings, failure to
function in a production environment, and bugs that hardly justify the price
tag.

In their attempt to weave the Geodatabase into the fabric of government
agencies and large corporations, which has the trickle down effect on
consultants who work for them (Water management agencies in this specific
application), they have come out with this "ArcHydro" concept.  RFPs are
coming out asking for "ArcHydro".

The book for arcHydro states right up front, (although you have to really
read between the lines), it is still a pre/post processor for real water
model simulation software to do what they do best.  However, it is obviously
biased from that other company's geodatabase approach.  In reading it thus
far, i really dont see why this cannot be done with GRASS and a RDBMS.

Has anyone implemented and used arcHydro?  If so, what is your thoughts on a
GRASS/RDBMS approach?

Would anyone find a corresponding open source solution document, which
unless conflicting with an existing name already, I will call "OpenHydro",
useful as an open source solution to what the proprietary company is
promoting in their latest round of propaganda?

I am forced to learn this ArcHydro procedure/framework to do a project our
company won, which called specifically for the implementation of ArcHydro.
However, through my readings and implementation, I plan on making the same
concept available through open source tools, specifically with the use of
GRASS and a RDBMS.

Basically I'm looking to find 1) anyone who has used arcHydro and 2) if
there is interest in generating an "OpenHydro" alternative using GRASS.

Surely all the open source developers and users are on the "nice" list of
Santa!

Wishing Happy Holidays around the world!
