      Full pathname of initial rtm file
flood_mode rtm_inparm rtm char ['ACTIVE', 'NULL'] $RTM_FLOOD_MODE 
      If ACTIVE, turn on rtm flooding back to clm. Note that rtm flood
      is not supported in CESM1.1
frivinp_rtm rtm_inparm rtm char ['any char'] UNSET
is $DIN_LOC_ROOT/lnd/clm2/rtmdata/rdirc_0.5x0.5_simyr2000_slpmxvl_c120717.nc for: {'rof_grid': 'r05'}

      Full pathname of input datafile for RTM.
ice_runoff rtm_inparm rtm logical ['.true.', '.false.'] .true.
is .false. for: {'lnd_grid': '48x96'}
is .false. for: {'lnd_grid': 'T31'} 
      If .true., river runoff will be split up into liquid and ice streams,
      otherwise ice runoff will be zero and all runoff directed to liquid stream.
nrevsn_rtm rtm_inparm rtm char ['any char'] 
      Full pathname of master restart file for a branch run. (only used if RUN_TYPE is branch)
rtm_effvel rtm_inparm rtm char ['ACTIVE', 'NULL'] ACTIVE
is NULL for: {'compset': 'CLM40'} 
      If ACTIVE, calculate the effective velocity using slope.
rtm_mode rtm_inparm rtm char ['ACTIVE', 'NULL'] ACTIVE
is ACTIVE for: {'rtm_mode': 'ACTIVE', 'clm_accelerated_spinup': 'off'}
is NULL for: {'clm_accelerated_spinup': 'on'}
is NULL for: {'rtm_mode': 'NULL'}
is NULL for: {'rof_grid': 'null'} 
      If ACTIVE, turn on rtm river routing. If the value rtm_mode is
      NULL, then rof_present will be set to false at runtime.
rtm_tstep rtm_inparm rtm integer ['any integer'] -999 
RTM time step (sec). - set automatically via the value of ROF_NCPL
