A pragmatic approach to model validation
Dick P. Dee · Coastal and estuarine studies · 1995
The recent initiative by several European hydraulic research and engineering institutes to start producing validation documents for computational modeling software is described. These documents are to contain claims about model applicability and accuracy, together with the available evidence for those claims. A brief discussion of recent literature on general aspects of model validation is included. We view model validation as a process of formulating and substantiating claims about model applicability and accuracy. This involves a broad range of activities: theoretical analysis of model assumptions, numerical analysis of discretization techniques, computational experiments on hypothetical test cases, comparisons between model results and laboratory measurements, case studies involving field applications, etc. A description and classification of distinct aspects of the validation process is introduced; terminology is carefully defined and included in a glossary.
