I've tooled around the forum for a while, but if there are easy hits on this topic they're eluding me.
All I want to know (for now, at least) is where to find and how to import precipitation data into SWMM5 for a rain gage.
I've downloaded files from the NCDC (DSI 3240), which come out as TXT files, either comma or space delimited. Are these useful to SWMM? It wants a DAT file, can I just change the filetype? Is the formatting of the NCDC's files alright for SWMM? I am in the process of trying to test this out a bit on my own, but thought it might be worth asking the group in the event that I can't figure it out on my own.
Any hints appreciated. Thanks!
