Good Hydrology Flood Software

[planit]

I am trying to analyze a channel to see if it can handle a 100 year flood event in our area. We have LDD but it doesn't have this kind of capabilities. Is there any freeware/shareware software available for this type of study?

Try going to

http://www.hydrocad.net

and downloading the free sampler. This helps me do my homework in hydrology class, and we do stuff similar to what you are doing.

Hydrocad is primarily a hydrology program. You need a program for hydraulics. Just use HEC-RAS. It's free, easy, and widely accepted.

Bayou is right. The hydrocad is good for hydrology, particularly basin routing, but HEC-RAS is the way to analyze a stream for capacity and flood elevation. I havent yet tried to analyze a reach or reaches using hydrocad, so I couldnt totally rule out its usefulness.
