Hello All,

I've been asked about what type of assessments people undertake to show that a sewer model is suitably calibrated.

Here in Victoria, Australia, we review individual sites (flow, depth and velocity) to determine the variation from the observed data is within a tolerance, but this is done at each individual site.

Is it possible to aggregate these up to provide one number that shows the fitness of the model as a whole ?

Has anyone done this type of holistic reporting on a model's accuracy ?

Interested to hear back about how/whether this is done in other parts of the world.

Thanks - Ann
