Hi
I am calibrating stream flow in SWAT-CUP, at the end of the simulation I am getting only one set of parameters. Like one CN2 value same for other parameters. In the case of curve number parameter (CN2) in the my study area every sub basin will get different CN2 value according to the land use and soil type values. How to see the CN2 values for remaining sub-basins ?
Can some help me to find out where the remaining values.
Regards
Dagani
You have to see each mgt. file of each subbasin in SWAT CUP project file where it will with hru number
The value of CN you are getting after the calibration refers to the average basin value. If you want to check the sub-basin wise CN value, open the management file inside inputs (.mgt). It will be useful during manual calibration method.
Dear Sonam Sandeep Dash
Thanks for your response.
- Is it possible to get the CN value for every sub-basin or based on LULC from the calibration process ?
- And, are you saying about .mgt file in SWAT project before the calibration(not in SWAT CUP). to see the basin wise CN values ?
if it is yes, I have checked the CN values in SWAT project file, for every basin. but question is can we get CN values for every sub-basin or based on LULC in calibration process or in any other way ?
Thanks in advance
Dear Dagani Koteswara Rao
The sub-basin wise CN values so obtained after calibration depends on the calibration approach. If you are using a multi-site calibration technique, then the CN values are true representative of your LULC dynamics. If not a multi-site calibration, the true values may increase or decrease by some percentage as a function of calibration parameter value.
