Hi all,

I am doing a study on how wetlands affect runoff. So for that I need to represent wetlands in SWAT+. After running the model, in the land use summary it shows the Curve number for the wetlands is o (just like the same for wetw). CAn anyone tell me why is that.

I am doing a sceanrio analysis how the wetland loss affect runoff

How can I represent wetlands correctly. (it is a land use category in my land use map)

thanks

Hello Oshadhee
Greetings,

I am also having the same issue with zero curve number with wetf and wetw. It didn't change even though I put different curve number categories like past_g (CN = 69 or open_p (CN = 79)
