Can HydroCAD do this?
(OP)
I may be in a situation soon where I have to show an analysis to a reviewer of how much runoff reduction an infiltration system provides over the course of a year. I suspect I'll need to punch in a hyetograph for an entire year on a day by day basis, route it, and compare rainfall totals to volumes of runoff and volumes of infiltration.
The system is already designed in HydroCAD, the question is how to do 365 days worth of back to back storms in it, and where to get the data. Alternately, what other software could handle it. I'd like to avoid EPA-SWMM if I could, for headache reasons.
Ideas?

RE: Can HydroCAD do this?
In order to run for a full year, you will need to increase the default maximum time span of 999.9 hours.
1) Open the project
2) Open the Settings|Units screen
3) Click the CUSTOM button
4) Scroll down and check the "RealTime" parameter
5) Change the maximum value to 9999 hours (more than a year)
6) Click OK a couple of times.
Now you will be able to set a time span of slightly over a year. Remember to increase the time step for your initial test. You can always reduce it later depending on the speed and available memory in your PC.

Is there any way to set the unit up to be days, or at least have each data point be 24 hours worth? I don't relish entering 9000 numbers into a text file sideways.

depth=

becomes:
depth= 1 2 3 4
However - The SCS/NRCS procedure is a single-event model, where the initial abstraction is applied only once at the start of the storm. If you're trying to run a continuous simulation you may need a different runoff methodology.
