**Description** Webinar number 176
Not all hydraulic solvers are the same, and models may or may not be fit-for-purpose, so how do you benchmark your software and model? Firstly, having insights to the physical processes the hydraulic solver emulates, and their relevancy to the modelling objectives is important, along with an appreciation of the mathematical sophistication used. There are also fundamental tests that can easily be carried out to establish if a model’s configuration is insensitive to assumptions and parameters.

The webinar discusses at an elementary level how to evaluate a hydraulic solver’s suitability and presents basic tests that can be carried out to help validate a model’s robustness. Hydraulic modellers and users of modelling outputs will find this webinar invaluable.
