[Qgis-user] River Flood modelling

[Saber Razmjooei]

AnuGA results are now fully supported in QGIS 3.5 mesh layer. You can load
the SWW file directly.

In addition, you can look into HEC RAS, the 2-dimensional results can again
be loaded directly as a mesh layer in QGIS. There is also RiverGIS plugin
which helps you build your model.

Regards
Saber
