What do YOU use HydroCAD for?
(OP)
I've seen a wide range of HydoCAD applications from simple detention pond designs, to underground detention and exfiltration, and even mine drainage systems! It would be interesting to know how others are using HydroCAD.

I like the way the program works, definitly less painfull than PONDS in MANY ways (price, ease of use, etc.).
So far I have modeled a retention pond and am working on resolving a flooding problem in a subidvision.

Still searching.

When using the SCS runoff method for Florida, HydroCAD includes the FDOT rainfalls for 1,2,4,8 and 24 hours, plus the 3,7, and 10 day rainfalls. (The complete rainfall library covers the entire country with over 50 distributions.)
You will generally have two "projects". One for the existing conditions and one for proposed. For each project, just pick each distribution and print the report. (The calculations are done automatically for each event.) You can then compare the results to identfy the critical event.
As for percolation, HydroCAD will do this any way you wish. There are a number of options that let you include or exclude percolation through the bottom of the pond. This is configured when you set up the "exfiltration outlet" on the pond.
You can test all this with the free HydroCAD sampler at www.hydrocad.net/sampler.htm

Are you talking about Hydraflow from Intellisolve? or HydroCAD from AMS?
I have used Hydraflow stormsewers.... I now see they have a product called Hydraflow Hydrographs which looks like it is along the lines of Hydrocad. Is that the product you are referring to?
I would highly recommend you get a demo of HydroCAd for comparison.

The results will be compared to a HEC-1 generated inflow peak, outflow peak and the peak flow generated from the use of the Rational Method.
RE: What do YOU use HydroCAD for?
I too have used both HydroCAD and HEC-HMS to see how the results compared. They were quite different in peak flows perhaps due to an apparent different treatment of the initial abstraction. Unfortunately, that study is for an ungaged site, so no calibration possible. I would be interested to see your results.
For a different project, HydroCAD was a breeze in designing a flow-control and detention structure for a commercial site using off the shelf manholes & pipes with a simple orifice & weir modification. Trial and error goes so fast, it was easy to hit two target flows (10-year and 100-year). I can't wait for the ability to input sloped pipes as "horizontal cylinder" storage however!

No routing through the outlets at the detention basin was made, nor overtopping flow considered with a wier outlet.
Hydrocad takes the HEC 1 results and by matching the peak and volumes, this comparison problem is evaluated it in minutes. Secondly, it provides the basis for increasing the detention volume through further excavation.
As I was explainimng the unzipping of the Sampler to a City of Tucson staff member, he made a first run in minutes after unzipping it. He is still stunned.
