6.4.7Maximum/Minimum Output

Maximum/minimum values for water levels at nodes, and flows and velocities in channels are output in three separate formats:

• 
  at the top of the .csv files containing the time-series output (see previous section);
  
• 
  .mif/.mid files with the extensions 1d_mmH, 1d_mmQ and 1d_mmV; and
  
• 
  at the end of the .eof file (good for viewing the time output in a text editor).
  

The GIS .mif/.mid files contain the maximum and minimum values, and the time of the maximum and minimum values, for water levels, flows and velocities. The files are given a “1d_mmH”, “1d_mmQ” and “1d_mmV” extension and contain the maximum, minimum, time of maximum and time of minimum values as attributes to the GIS objects at each node or channel. For the flows and velocities, an additional attribute (Qpeak and Vpeak) equal to the maximum of the maximum and minimums in terms of magnitude is provided – this is particularly useful for tidal reaches or where a channel has significant flows in both directions.

The water levels are output at the nodes and flows and velocities at the channel midpoints. The flows and velocities are shown as arrow symbols scaled according to their peak value (if they do not appear as such, then the Wingdings font set is not installed on your computer). The direction of the arrow is in the positive flow direction.
