Hi Jessica,
Another way to explore is via the use of a GIS, specifically MapWindows which is an opensource program. There is a plugin called inp.PINS <http://www.mapwindow.org/apps/wiki/doku.php?id=inp.pins> which can be utilised. The description of inp.PINS is as follows:
Use this tool to generate SWMM input file (.inp) based on GIS files (shape and DEM grid files) and also, after SWMM modeling, to built flood plain shape files by combining the result SWMM file (.rpt) with a DEM grid.

The URL is http://www.mapwindow.org/apps/wiki/doku.php?id=download
Hope this is of help to all SWmm users.

Jessica,

I would suggest creating a quick dummy model, draw 1 or 2 subcatchments,
save, exit and examine the input file for the model. There will be a
section called POLYGONS where the coordinates of the subcatchments you
drew will be shown. Assuming you can easily export coordinates for your
shapes you should be able to reformat the data to meet the swmm input
file requirements. You can add the information for the other data
sections as well if you desire.

Subject: [SWMM-USERS] Importing shapefile subcatch areas into SWMM

Hi,

Is there a way to automatically import subcatch areas into SWMM? I have
a large number of vector based shapefiles that I would like to utilize
as subcatch areas. If importing the shapefiles directly doesn't work,
is there a way to automatically just import a text list of areas with
the corresponding subcatch parameters into subcatch areas.

Thanks,

Thanks all, for the suggestions. They were all helpful. Is there a limit to the number of shapefiles SWMM can support? I have over 100,000 small subcatchment areas. I was thinking of just taking a representative random sample based on the areas.

Hi Jessica,

There is no limitation on the number of subcatchments in SWMM 5 or a limit on the number of polygon vertex points that make up the boundary of the subcatchments in the SWMM 5 text input file. I hope this answers your question.
