I am looking for some advice for a master’s thesis. My field is civil engineering (water, to be specific), but my interest is software and I’d like to do something that would support open source, and be fun for me, i.e. some programming. I’ve had a couple of ideas so far, e.g. grass modules for floodline analysis, possibly based on cfd. But I’d like to do something that would be useful to the Grass development team. So does anyone have any suggestions of software I can write, which would be technical enough to satisfy the requirements of a masters thesis and support Grass development?
If you come from a hydraulics background… one very important need is the ability to generate channel cross-sections interactively for, say, HEC-RAS and then do flood inundation mapping from HEC-RAS from the modeling results — I would think this would be a huge contribution.
Regards,
Tom

I would love to see some tools for corridor mapping and analysis. I
came across grass because of its r.profile routine when I had to do
deal with a LIDAR survey of a 70 km x 400 m corridor for a path, but I
was not able to do much with it.
Here some links to examples of engineering that needs GIS:

to get a good cross section you need to set it perpendicular to the river's
center line. Which means you need a good river centerline. Which means you
have to deal with the "river mile problem".
raster tools are not always good here as the river can be very thin
compared to the overall length leading to untenable resolution settings
to get an good result. (r.cost + r.param.scale to pull out the cost
ridges or r.slope.aspect to pull out the maxima from the 1st derivative
of the cost works, but the resolution issue gets ya)
any thoughts? some sort of reverse v.buffer?
small islands within the river also cause havoc with many computational
approaches.
