Dear SWAT Experts,

I have daily discharge data collected from the year 1983 to 2013 from Central water commission, Govt of India. This data unit is cubic meter per second (cumecs). I will be compared with SWAT Simulated the monthly surface runoff (SURQmm) of the outlet Near Karur(Nallamarampatty). I have adopted the following formula, Observed data converted into Monthly total discharge for example: 4.9 cumecs*60*60*24*No of flow days.

Sir,

I have also the same problem.

I have data of discharge in cumec but the output of swat in mm.

Is it working the method you have used to convert the cumec data in mm because after doing the calculation you will get the out in units of cubic meter. Then how you are further proceeding ?

If I am wrong please correct me.

I am facing the same problem

Thanks

Rahul

SWAT also gives the results in cumec. Just consider the results from Output.rch file. Just run your model on a monthly basis and in txtinout folder, please consider the results from output.rch file. It will give you the outflows at the outlet of each subbasin considered upstream sub-catchments.

Read SWAT Manual.
