Hello!
Changing of routing parameters msk_co1, msk_co2, msk_x (in parameters.bsn), and mann (hyd-sed-lte.cha) doesn't change the discharge in the results (flo_out in channel_sd_day.txt or channel_sdmorph_day.txt).
For sure, msk_co1, msk_co2, msk_x are used for Muskingum routing method (rte_cha = 1 in codes.bsn)
mann is used for Variable storage routing method (rte_cha = 0)
I will be grateful if you check the sensitivity of these parameters in your project.
Thanks, Valeriy, Ukrainian Hydrometeorological Institute
