Hi all,

I am running ArcSWAT on a snow dominated system. My precipitation values are derived from GCHN SNOTEL, AWOS, COOP, and CoCoRaHS sites. After a run, SWAT Error Check indicates contribution from precipitation is 0, surface runoff is too low, gw recharge is too high, etc. I imagine this is an issue with my pcp input file. Any suggestions?

Thanks much!

Justin:

I see from the precipitation file you are generating rainfall for several gages for many days. This could indicate that something is not correct in your weather generator files. The model uses these values for generating the missing days. I will be glad to take a look at this if you send me your current txtinout (.zip).

Thanks,

Nancy
