Classic Solution Scheme
A newer TUFLOW release is available (2023-03-AA). However, a
legacy version of TUFLOW has been adopted to ensure consistency
with the previous modelling / calibration.
TUFLOW HPC solver solution scheme is recommended for this
detailed overland flood study. Since natural channels are being
represented as 2D topography in the model, sub-grid sampling
(SGS) is also recommended to represent the storage and
conveyance more accurately within these channels which
otherwise would be constrained by the 2D resolution.

other files
Folder structure is consistent with the TUFLOW User
Manual 2018-03.
Run files include *.tcf *.ecf, *.tgc and *.tbc.
There are two tcf9s that appear to be the latest
iteration. One for calibration runs, one for design runs.
