6.4.5GIS and Text 1D Domain Check Files

GIS check files of the network, initial water levels and boundary conditions are produced using Write Check Files (also see Section 6.2). These files are based on the final 1D domain inputs after any overrides. Text .csv files containing any 1d_ta link tables and 1d_bc boundaries are also written so that the tabular input can be cross-checked.

6.4.6Time-Series Output

Time-series data for water levels at nodes, and flows and velocities in channels are output in three separate formats:

• 
  A .csv file that can be used in spreadsheet software or similar to produce graphs, tables, etc. (the data can be output with values for a node/channel along rows or down columns – see CSV Format).
  
• 
  An _TS.mif file that can be used for graphing time series in a GIS provided appropriate graphing are tools are available as shown in Figure 7 .12 (this was released in Build 2003 05 AC). Note, in MapInfo, only the first 249 output times are available as there is a limit of 250 attributes. Other GIS systems have yet to be tested at the time of writing. Also see Output Times Same as 2D. As of Build 2005-05-AN, only the first 245 output times are available as the 2^nd to 5^th attributes are used for the maximum and minimum values and the time in hours of the maximum and minimums. The graphing tool has also been updated to recognise the presence of the maximums and minimums information.
  
• 
  in the .eof file (good for viewing the time output in a text editor).
  

The .eof file contains a complete output of all results including flags to indicate the various flow regimes.
