    8 Once this up-scaling has been completed and verified, then the files will be used for conducting
    9 a convergence study in ANUGA. This component is still in development.

     9The "up-scaled" files are then used for conducting a convergence study
     10in ANUGA.

     44get_timeseries.py
     45  This script extracts timeseries from the sww file and writes them to individual
     46  csv files for each gauge location.
     47
     48export_results.py
     49  This script extracts a number of variables from the sww file (for eg stage,
     50  depth, momentum) in three regions at three different but fixed regular grid
     51  resolutions (at either discrete time indices or maximised over the whole
     52  simulation).
