"Invalid file header" error

[Aaron Ruesch]

Hello all,

Has anyone come across this error before when writing parameter adjustments when running SUFI2_run.bat (see attached for screenshot)? It seems to have popped for no reason on a SUFI2 project that was previously operating perfectly well. I overwrote all the *.hru files in my project, including those in the backup folder, with my originals to test if there was an issue with my configuration text files. I also tried replacing my par_inf.txt file with one that used to work to test if there was an error with my parameterization that I wasn't catching. Neither of these seem to be the issue. I'm stumped.

Thanks,

Aaron

What is parameter number 68?

It was also SURLAG. In this case, I was filtering SURLAG by soil texture--I remember reading somewhere that SWAT-CUP creates a soil type/texture lookup table to be able to accomplish this type of filter. Could this lookup table have been corrupted? I looked for a file that contained this information and I could not find one.

To note, I recreated my SWAT-CUP project with the exact same TxtInOut and it started working again.

SURLAG is in the basin file. There is no soil type distinguished at the basin level. You can see that in the first line of the basin file

So, you cannot do that.

[Aaron Ruesch]

Sorry, the HRU-level SURLAG is what I was adjusting. I should have specified.

[Abbaspour, Karim]

What is that? In which file is it?

[Aaron Ruesch]

Since Rev.627, SURLAG is both/either a basins.bsn and *.hru parameter. If the *.hru SURLAG parameter is <= 0, it defaults to the basins.bsn value. In my case, I am adjusting *.hru SURLAG values.

[Abbaspour, Karim]

OK, in that case it is not yet in the swatcup.

Hi Karim,

It is actually in SWAT-CUP. I used SURLAG.hru to calibrate for the Tocantins basin and am using to calibrate for the Amazon basin. If I am not mistaken you added them when you was in College Station as Srini recommended.

Kind regards,
José

[Abbaspour, Karim]

OK, thanks Jose. I had forgotten about that. Then I don’t know where Aaron’s error is from.

Hi

Did you ever get this problem solved? What was your option to go with when you got this error? I faced a similar error which never happened when I did the same process a year ago while running the model.

Thanks.

[Aaron Ruesch]

Hmmm...I must have solved it at some point because I no longer have that issue. My guess is that I reverted to an earlier state of the model though, rather than trying to debug. I'm sorry to say that I don't have a memory or record of what I did.

Hi,

I encountered the same problem. You may want to try "restore files from backup". It solved the problem for me.

Thanks,
