Hello SWAT Users

I calibrated a SWAT-CUP model and I'd like to know the percentage of each subbasin that is covered with snow at the end of each time step, how can I do?

Best regards, Mitchel

Hi,

The snow area depletion curve.

Hi Steve,

Thanks for your answer. I found in the SWAT manual the SNOcov formula, which depends on SNO, SNO100, cov1 and co2. This is the formula that I need to use? You know where I can find this parameters?

Hi Mitchel,

Yes, that is the formula I would use to get fractional snow covered area. You can solve for cov1 and cov2 using constraints on the snow area depletion curve described in the theory manual. These constraints give two equations, two unknowns.
