!              ------------   ---------  ---------

!            - This variable contains the number of timesteps
!              per day for which erosion is calculated.

!     erod_interval - surface updating interval within erosion.

!              range values      min       max

!              ------------   ---------  ---------

!            - This variable contains the number of seconds
!              the surface is updated within the erosion submodel.
!              (currently settable as a commandline option within
!              the standalone version of the erosion submodel)

!     am0jd  - Current julian day of simulation
