swat cup observation file

[Visakh Raja]

i m using swat cup. i m here by submitting the details

i run the swat model from 2003 to 2013 i.e 11 years

after that i started calibration using swat-cup

i have observed values from 2003 to 2007.

my doubt is weather i need to give observation values from 2003 to 2013 or is it sufficient to give a maximum of 5 years( from 2003 to 2007). 

because when i am giving 2003 to 2007 as input to swat-cup i m getting error like "simulation no 2 in variable 1 is misssing".

please help me......

hi

i tried with the below details i cant able to run the calibration. i here by submitting the echo files in the swat cup. please take a look at those files and suggest me an idea. i cannot find any error in these files.

Dear,

Please follow the user manual carefully. Please be specific on the problem. Hardly anybody would have time to go through all the files that you have attached.

Can you pin-point your problem?

in swat my project duration is from 2003 to 2013 with 2 years of warm up period. I run the simulation successfully. after that for calibration i am using swat cup. in this i am using the observed data from 2005 to 2010. i hereby giving all files in txt format. please have a look at these files and help me to find the error.​

thank you in advance

with regards

Dear,

You have years of 2003-2011.

Allocate 2 years for warm-up: 2003 to 2004.
For calibration period: 2005 to 2010, a total of 6 years
For validation period: 2011 to 2013, a total of 3 years

For this scheme, do the followings:

1. FILE.CIO (run up to calibration period)

  11      | NBYR : Number of years simulated
  2003    | IYR : Beginning year of simulation
............
.............
  2    | NYSKIP: number of years to skip output printing/summarization
  1    | IPRINT: print code (month, day, year)

2. sufi2_extract_rch

output.rch     : swat output file name
1              : number of variables to get
7              : variable column number(s) in the swat output file (as many as the above number)

29              : total number of reaches (subbasins) in the project

1              : number of reaches (subbasins) to get for the first variable
29 (check this)          : reach (subbasin) numbers for the first variable (is this true? you have the observation at reach_out_29?, which for me looks like the most-upstream subbasin)


2005           : beginning year of simulation not including the warm up period
2010           : end year of simulation

1              : time step (1=daily, 2=monthly, 3=yearly)

3.Observed_rch.txt

1     : number of observed variables

FLOW_OUT_29   : this is the name of the variable and the subbasin number to be included in the objective function
2191 (check this, do you have total of 2191 observations?, if missing then delete it, but keep the sequence)   : number of data points for this variable as it follows below. First column is a sequential number from beginning
      : of the simulation, second column is variable name and date (format arbitrary), third column is variable value.

1	FLOW_OUT_1_2005	57.455
2	FLOW_OUT_2_2005	75
3	FLOW_OUT_3_2005	61.123
......
......
2191	FLOW_OUT_2191_2010	17.297 (in here, better to rename it FLOW_OUT_365_2010. It does not matter but this looks more natural, the flow of 365th day of 2010)

4.observed.txt
- It looks OK, if you have correct data at #3.

5. At other files (e.g: var_file_rch.txt; var_file_name.txt), keep specifying, FLOW_OUT_29.txt (if 29 is correct flow out at which you have observation), I think this is a wrong reach out number)

Hello,

In previous reply, change this:

1. FILE.CIO (run up to calibration period)

  8      | NBYR : Number of years simulated (not 11)

  2003    | IYR : Beginning year of simulation

thank u all for your support.

I cleared that error.

after running 2 iteration when i checked the summary it is showing R2=0.22 and NS=-2.22

is it correct or what should i do for that?
