Hydrographs

SWAT+ prints two hydrograph output files per time step, one for incoming and one for outgoing hydrographs. The printing of hydrographs is controlled by entering "y" or "n" in the hyd line in print.prt. Hydrographs can be printed at daily, monthly, yearly, and average annual time steps. The names of the hydrograph output files are as follows:

• hydin_day.txt

• hydout_day.txt

• hydin_mon.txt

• hydout_mon.txt

• hydin_yr.txt

• hydout_yr.txt

• hydin_aa.txt

• hydout_aa.txt

The number of lines in the hydrograph output files depends on the number of connections between spatial objects defined in the SWAT+ setup. In the incoming hydrograph files, for each receiving object there will be one line per source object it receives a hydrograph from. The number of lines per source object in the outgoing hydrograph files equals the number of receiving objects it sends hydrographs to.
