I have been working extensively on calibrating the monthly evapotranspiration (ET) for the entire basin, but so far, I have not been able to achieve satisfactory results. I would like to seek your advice on the following points:
1- Should I use the "lsunit_wb_mon.txt" file or the "basin_wb_mon.txt" file for this process?
2- What specific steps or considerations should I take for the Reach_Unit during this calibration?
Your guidance on this matter would be greatly appreciated.
Thank you in advance for your help!
