Shawn,

There are multiple ways for you to import a GW time series into SWMM 5. One way would be to have external files for each groundwater node that want to connect to the watersheds in SWMM 5. Here is a example that will bring in a flow time series to a watershed called Shawn.

"GW Time Series Data for Watershed Shawn
Name Date Time Value
01-01-1988 00:00 0.00000
00:06 0.50000
00:12 1.00000
00:18 10.00000
01:24 50.00000
12:00 10.00000"

You can do the same with any external time series (for example, an RDII time series or a time series from HEC-HMS or TR-55). There will be other methods for importing time series in SWMM 5 - this is just the one I am most familiar with right now.

The GW routine in SWMM 5 is still under construction, BTW.
