General

  • Total time (TOT_TIME) – An integer giving the total duration of the simulation in minutes
  • Time step (TIMESTEP) – An integer giving the duration of each time step in the simulation in seconds. The time step must be evenly divisible into 60 seconds (e.g., 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, or 60 seconds).
  • Outlet slope (OUTSLOPE) – The slope of the cell containing the watershed outlet. This must be a positive decimal number.
