Error running SWAT

[sam_dc]

Dear SWAT users,

I am new user to swat in general and SWAT_CUP in specific. I am trying to calibrate my model based on three year of observed data. Every time I run SWAT the model entered in an endless loop. The run never finished. Any advise or help would be highly appreciated as I am completly stuck now

My input files are as follows:

You should simulate from beginning to the end of the year, don't stop at day 274. Swatcup has problems with this!

In the next versions I try to make this flexible.

Dear Karim,

First, many thanks for your response. Second, I changed the end of the simulation to be the end of the year 365 but unfortunately that didn't help. SWAT_CUP_SUFI2 continued to run in an open loop. It did simulation #1 and that's it never move to simulation #2.

Could you please advise in this matter.

Year 2000, end of simulation, is a leap year and should gave 366 days in file.cio. Also, in your climate files you need to have data until 2000366.

Best, Karim

[aggie...@gmail.com]

I updated my file.Cio file to account for the leap year "366" days. I also updated the observed.txt and observed_rch.txt but problem still exists. I tested another scenario by having observed data only for years 1998 and 1999. I updated input files accordingly to end by 365 instead of 366 day this time and problem still exists.  

The run enters an open loop and never ends.

Regarding the climate data, the original run I have in SWAT was for 26 years starting in 1987 and ending in 2012. Both pcp and tmp files have data up to year 2012 therefore I do have climate data to cover the observed period.

[Karim]

... zip your project and send it to me to have a look...

Best, Karim

Many thanks Dr. Karim for your comment. I had to update IPRINT in file.cio to match the output defined in swat_cup. After this update the run went correct..Thank you again. 

[yudan1...@gmail.com]

 Does it have to simulate integral year from the begining  day to the end day such as 1 year,2 years,3years....in swatcup? If I only want to simulate 3 months, then it can't work correctly, right?

yes, for now, you have to simulate the whole year...

Then the SWAT model is not capable of simulating the floods event. It seems that the model is suitable for continuous and  long term simulation. Right?

why? Don't see the connection there....

The flood events usually occur in just a few months in one year. I  just want to  simulate the flood period.I can achieve this purpose in other hydrological model such as HEC-HMS.But I can't do that in SWAT model as mentioned above that I can't just calibrate a few months.

well, simulate a year and just look at those few months....anyhow you need to have a few months/years of warm up period.

Best, Karim
