SWAT+ prints two channel output files per time step, one for general channel output and one for channel morphology output. The printing of channel output is controlled by entering "y" or "n" in the channel_sd line in print.prt. In addition, a basin average of all channels can be printed by entering "y" in the basin_sd_cha line in print.prt. Channel output can be printed at daily, monthly, yearly, and average annual time steps. The names of the channel output files are as follows:
channel_sd_day.txt
channel_sd_mon.txt
channel_sd_yr.txt
channel_sd_aa.txt
channel_sdmorph_day.txt
channel_sdmorph_mon.txt
channel_sdmorph_yr.txt
channel_sdmorph_aa.txt
basin_sd_cha_day.txt
basin_sd_cha_mon.txt
basin_sd_cha_yr.txt
basin_sd_cha_aa.txt
basin_sd_chamorph_day.txt
basin_sd_chamorph_mon.txt
basin_sd_chamorph_yr.txt
