Problem with hourly flow calibration

[Hanzala Khan]

Dear Dr. Abbaspour and SWAT-CUP users,

I have developed SWAT model for a coastal low gradient watershed using stage-iv hourly rainfall data. Now, I am trying to calibrate hourly flow SWAT using the SUFI2 SWAT-CUP. I have tried many iterations (upto 1000 simulations) but the results are not changing. Every time I get the same results and the model returns simulation 1 as the best simulation (Best_sim_no= 1).
Then I tried to calibrate the model using daily flow data and it works completely fine. I don't know what's the problem with hourly flow calibration. I have attached screenshot of all the necessary files. Your help and response will be highly appreciated.

Thanks,

Hanzala

Hi Hanzalak,

                         Did you solve this? I'm suffering by error in hourly calibration  in the attachment. Do you have a solution?.

Hello Bhim Ghale,

Sorry I don't have a solution to your problem. My hourly SWAT CUP is working fine but the result doesn't make sense as none of the parameter turn out to be sensitive.

I am looking for help.

Thanks,

Hanzala

Is your SWAT cup is 2019 or 2012 ?. 

Could you share the file ??

Hi Hazanlak,

                        I solved this problem. Your problem is due to the observed discharge data error.

Best Regards

Hi Bhim

I have kind of the same problem. My parameter value changes, but my NSE value remains the same. What can be the problem?
