Hi
Somewhere between 5.3-7 and 6.0-1 , a number of hydraulic modeling
tools were left out of the CVS tree.
Are there reasons (beyond time, workers and interest) to not overhaul
and bring back some or all of these tools ? Are they being worked on
as part of a raster revamp ?
I have been working on r.hydro.CASC2D with some results. The patch
would be a little bit large to just throw on the mailing list and I am
wondering just what to do with it.
Thanx
Ray

It's been a problem of too much code and too few active developers.

You can send to me directly if you like. I'll review it and commit
working code.
Also, if you have a test scenario(s) (preferably with Spearfish
dataset), please forward that as well.

Is there a list anywhere of what remains to be ported or outstanding
issues with hydro model tools in current version?
Are there any developers that need a little cash to speed up getting
some of this fixed up? Perhaps a few of us who are interested could
pool some re$ources to help get these tools back into working order.
Anyone else interested/able in putting some funding into the pot? Any
developers interested in committing to a timeline and making some cash?

What tools are you talking about exactly?
Hydraulic? Or do you mean hydrologic or just water related?
In that case JGrass has a whole bunch of "water-related" tools and is based on
the GRASS raster format. I know some people have issues with java 
In every other case I would love to know which modules you are talking about
(apart the already cited r.hydro.CASC2D, which seems to be a hydrologic
module).

just a note regarding this - most hydrologic modeling tools that were developed or linked to GRASS
in 90ies and not ported to GRASS6 usually need more than just porting. Compared to their current versions
(if they exist) they are very much behind so they also need some serious upgrade
(this is true also for the simwe modules).
I have emailed to Fred Ogden who is one of the co-authors of casc2d to find out what he thinks should be done
but I don't have an answer yet. The same should probably be done for answers, swat, r.water.fea and others.
Also, there are several efforts in development of new hydrologic modules that I know of but I will
leave the announcement to authors when they are ready.

java
FYI there are efforts underway to get JGrass running with Free java
work-alikes (classpath, kaffe), which may give a 100% Free toolchain one
day. This is still a bit far off but things are much closer with
OpenJUMP*, see:
http://pkg-grass.alioth.debian.org/cgi-bin/wiki.pl/PackageList
[*] already in the DebianGIS repo regardless of what that page says.

I subscribe to what you are saying here Helena.
Also looking forward to see what new tools are on the way in this field.

Yes Hamish,
you are right, even if OpenJump lacks of hydrologic tools.
We decided not to wait for the free implementations of the Java Virtual
Machine, since that would block us from staying in line with new tecnologies.
We are now on java 1.5 and the site states: "contrib - needs jdk1.4, several
contrib packages", so I don't think that jgrass will be soon aligned with the
free JVM's. As soon as the mustang 1.6 will come, we will jump into that
since the opengl pipeline which we use is integrated in the JVM.
I don't want to start a discussion on that, just making clear what our
thoughts are.
In my opinion people should think about what JGrass can give to them, and that
it tries to keep in line with GRASS formats supplying a possibility to
develop in java (which is largly used), and not that the JVM is not GPL... a
lot of work is done by few people in JGrass and I feel strange in thinking
that someone would not exploit it because of a different flavor of its
religion.
Best regards,
Andrea
