Inundation time file (inundationtime.63)

The inundationtime.63 file records the total time that an initially dry area is inundated beyond a certain inundation threshold depth specified in the fort.15 file in the inundationOutputControl namelist by the parameter inunThresh.

The writing of the inundationtime.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 datasets. The first dataset records the total accumulated time in seconds that a node was inundated beyond the threshold. Periods of inundation are counted toward the total time, even if they are not contiguous. The second dataset records the time of onset of inundation beyond the threshold in seconds since cold start. The time of onset data are useful in the context of real time model guidance for decision making.

The basic file structure is shown below. Each line of output is represented by a line containing the output variable name(s) in bold face type. Blank lines are to enhance readability. Loops indicate multiple lines of output. Definitions of each variable are provided via hot links.

Output may be in ascii or netCDF format depending on how NOUTGE is set in the Model Parameter and Periodic Boundary Condition (fort.15) File.

Notes:

The inundationtime.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. The data in the inundationtime.63 file only record maximum inundation depth in areas that are initially dry, according to the initiallydry.63 file.
