1. By default, user output files are written as netCDF (‘N’) or unformatted
binary (‘U’) files depending on whether -DCDF compiler option has
been specified or not. These defaults can be reset by the user in the
usrdef tsr params, ... routines in the appropriate Usrdef files.
2. The status of open boundary forcing files is (re)set to ‘N’ (undefined) if
the appropriate switch is not set. For example, modfiles(io 2uvobc,:,:)%status
is set to ‘0’ is iopt obc 2D=0.
Model code
The following files have been created or modified
Inundation Schemes.f90
The following routines, only called if iopt fld is non-zero, are defined
here
mask function
The routine is called by coherens main at the start of
the predictor time step and
• evaluates one or more mask criteria
• set a cell to dry (at the C-node) if the criteria
return .TRUE.
• block the surrounding U- and V-velocity nodes
• set the currents to zero at blocked velocity nodes
minimum depths Use (19)–(21) to set the total water depths and surface
elevations to their minimum values where necessary.
The routine is called from water depths.
drying factor
Evaluates the drying factor α at each 2-D time step.
The routines is called from surface elevation.
