Anyone know of 1-, 2-, or 3-D hydraulic flow models that can be integrated
with GRASS?
Rich
Not sure if you are talking about groundwater models or surface water models but right now you have at least 2 surface models integrated in GRASS: TOPMODEL and SIMWE. They can be found in the Raster–>Hydrologic modeling menu. There were two simplistic Groundwater models (2D and 3D with no more than one layer) I can’t find them in the last version but I’m sure you can dig them out.
Hope that help

Kapo,
r.topmodel, r.sim.sediment, and r.sim.water are hydrologic models. That
is, they model water flow over the terrain and (with the later two) identify
erosional and depositional areas for sediment transport. I know that often
'hydrology' refers to all water flow, but I'm used to distinguishing between
surface flows (hydrology) and in-channel flows (hydraulics).
What I would like to acquire are tools similar to those of the National
Center for Computational Hydrodyamics and Engineering (NCCHE) at the Univ.
of Mississippi (USA). Unfortunately (from my perspective) their software
runs only under Microsoft and requires ARC/Info v.2 or 3. I run only linux
and want to integrate in-channel flows (flooding, morphometric changes) with
GRASS.
Thanks,
Rich
Hi Rich!
You seem to search for the same things that I am doing (or at least try
to do).
It would be great if such things once get integrated somehow into GRASS
or any other OpenSource Tool.
I know it becomes offtopic now - but I begged Gernot Belger from
bjoernsen engineers to make a linux version of their tool available for
download .. And he did - And probably we can make them releasing it for
linux on a regular base once we're more linux users..
As they use eclipse and java it seems not to be _such_ a problem.
So probably you point your browser to
http://sourceforge.net/projects/kalypso/files/
Thats the only hydraulics solution for linux that i am aware of.
If you know others we could start an "knowhow" interchange
regards
Werner

Werner,
I found some code from the US Geological Survey. Most are for ground
water, but some are for surface water. There's also code from the US
Environmental Protection Agency for chemical transport. One application was
originally written for DG/UX in FORTRAN-77 and I don't know what will happen
if I try to build it on linux.

I'm sure there are plenty of GRASS users running linux. That's the only
platform for which it was available for a long time. And, since that's all I
run I pay no attention to anything Microsoft.
As they use eclipse and java it seems not to be _such_ a problem.
There's a java2python application.
Thanks,
Rich

probably you want to have a chat with Soeren, I think there's some new
stuff going into grass 7 recently.
