As a TUFLOW user in Local Government we are often put in a position to check TUFLOW models. One aspect that needs checking is the location of cross section data, and the continuity of capacity along various reaches. That is, the cross sectional area / conveyance progressing from one cross section to the next. I have been searching for tools to do this but as yet have not found anything suitable. Is anyone aware of such a tool that allows both users and checkers of models to quickly assess the many cross sections that may occur within a model? I had started working on a python tool and was hoping to find a tool in the QGIS TUFLOW tool ...

On this topic, what is the best way to review the shape of cross sections and the lengths of reach over which they have been applied ?

I am going through a model that is modelling flow down a 4% - 7% grade and the results are showing Sub-critical flow with Froude ~ 0.6 - 0.8. When I do simple hand calc checks I am expecting Froude to be up around 2.0 ? What could be impacting the model. I have noticed that one of the materials layers has two overlaping surface roughness definitions? How is this resolved ?
