USLE - Soil loss during the time step

[Philipp]

hi there,

hope someone can help me here.
I found in Chapter 32 - SWAT Output Files that USLE is the synonym for soil loss during the time step!

But when I look it up in the output.std I only find USLE_LS! Is that the same????

Thx a lot...

[Philipp]

its me again,

o.k USLE_LS is the equation length slope (LS) factor!
But where do I find USLE or is USLE = SEDth in hru_output_file?

any suggestions?

[Philipp]

I just want to find out how much sediment is lost per HRU or sub-basin!

any suggestions would be great...

If you want to find out how much sediment is lost from an HRU, use SYLD in the output.hru file. From subbasin (output.sub), use SYLD as well. I usually use the main channel output file (output.rch) and the column sed_out to examine outputs from SWAT. Check out the input-output documentation of swat: http://swat.tamu.edu/media/69395/ch32_output.pdf

Good luck!

Alex
