(OP)
Anyone have a chance to try this program yet off the EPA website for stormwater analysis? Any problems to look out for? Quirks?
Western Washington Hydraulic Modeling, Revision 3. I guess revision 3 has only been out now a month or so. I just downloaded it off the site this weekend. I also have Hydrocad, but thought I would give this a try too.

I've not used this program but I believe it is calibrated for western Washington state only. I work mainly in Oregon so I'm assuming it wouldn't be useful here, or anywhere else, without local calibration data. Is that your understanding too ?

The key word is Hydrology, not hydraulic.

Look to the programs section on the left and search out stormwater. It is in this section and version 3 is listed as new - since mid September I believe. It has three sections to download - the program, the hydraulic database, and the manual of 95 pages.
Good hunting.

The main program should be able to be linked to a compatable hydraulic database for your region if the EPA has one. Notice that it did come tin three downloadable sections, one of which was the database. Why not ask your local EPA office?

I'll look, but I'm very doubtful there are databases available from EPA or anyone else. Let's both hope someone in Washington state responds to your post.
good luck

This is just a reminder that the WWHM3 seminar is next Wednesday, October 17th at the Red Lion at the Quay.
Please attached brochure for more information. As you look at the brochure please note that the day mentioned of Thursday October 17th is incorrect. The date of the 17th is correct, but the day is Wednesday not Thursday.
Hope to see you there.

RE: WWHM3
WWHM, WWHM2, & WWHM3 are WA state specific GUI front ends for the HSPF computational engine. I haven't tried WWHM3 but read about it. I hear that there may be a version of "WWHM3" that's been developed for part of California. These programs were developed (prior to WinHSPF) in response to WA state adopting a stormwater flow control standard that can only be assessed through continuous model simulations. The state was not comfortable that us dumb engineers would be able to figure out HSPF so they created WWHM as a more limited yet more user friendly (than DOS-HSPF) program with consistent output reporting that agency staff could review to assess if a project complied with the flow-duration standard.
With WWHM2, I don't recall an easy way to import or manipulate WDM files, which would be key to changing the geographic region. WWHM2 was set up entirely around WA state code and would not easily analyze projects that used a different criteria than WA state flow duration criteria, and was not usable to track water levels in ponds as is needed in cases. I found WWHM2 to be limited to the specifics of designing a flow control system to meet WA standard for flow duration control. Maybe WWHM3 is somehow more flexible (but I doubt it really addresses these issues, WA state is not paying their consultant to develop a nationwide tool!)
For nationwide continuous modeling tool IMO the preferred freeware/gov't sanctioned option would be EPA BASINS4.0, which includes WinHSPF, in part because EPA provides a WDM database (rainfall records, ET records, etc to use for input), or SWMM5. But really, who can afford to set up continous models for a project if the local code does not *require* it like here in WA.... until then CN based methods will likely continue to be the most cost-effective modeling approach.

You mentioned "October 17th at the Red Lion at the Quay."
I do not know where or what the Quay is... is this in Portland, Oregon?
Any link to register? Thanks

The Inn at the Quay is a restaurant in Vancouver, WASHINGTON, NOT B.C. Contact Ryan Jeynes at the phone number or website link provided in my post.
I was simply forwarding, for your information, an email Mr. Jeynes had sent to me.
If you live or work in WA, this may be a useful seminar to you. I live and work in Oregon so I will not attend but I did find BLTSeattle's post very helpful ( as usual). Please read it too.
good luck
