Definition of Model validation:
Model validation is the formal confirmation of the model quality criteria achieved in model calibration. For model validation a set of independent data is used and the model forcing and model parameters are fixed (which is not the case for model calibration).
This is the common definition for Model validation, other definitions can be discussed in the article


This definition is based on practical experience in modelling surface water behaviour. See also Reduction of uncertainties through Data Model Integration (DMI).
