Everdried.63: Dry Node Flagging File

The everdried.63 file was created to support harmonic analysis by flagging all nodes that had ever become dry during the course of a simulation. These data are useful to harmonic analysis because a node that goes dry for a single time step has a -99999 recorded for its water surface elevation, which contaminates the harmonic analysis solution.

The writing of the everdried.63 output file is activated when the inundationOutput parameter is set to .true. in the optional inundationOutputContol namelist at the bottom of the fort.15 file.

The file contains two data sets: 1. Wet/dry state information: -99999.0 if a node ever went dry during the simulation, 1.0 if it was wet for the entire simulation 2. Total time in seconds that a node was dry during the simulation (0.0 if it was always wet)

File Structure

The basic file structure is shown below. Each line of output is represented by a line containing the output variable name(s). Loops indicate multiple lines of output.

RUNDES, RUNID, AGRID
2, NP, DTDP*:ref:NSPOOLGE <NSPOOLGE>, NSPOOLGE, IRTYPE
TIME, IT
for k=1, NP
   k, everdried(k)
end k loop

TIME, IT
for k=1, NP
   k, driedtime(k)
end k loop

Notes

  • Output may be in ascii or netCDF format depending on how NOUTGE is set in the Model Parameter and Periodic Boundary Condition File

  • The everdried.63 file is written at the very end of the simulation, after timestepping is complete

  • The values only reflect the current run, even if the run was hotstarted
