Some Remarks on the Calibration and Validation of Numerical Water Quality Models

Research output: Contribution to book/anthology/report/conference proceedingArticle in proceedingResearchpeer-review

Abstract

It is a general experience that complete deterministic water quality models for aquatic systems most often show surprisingly poor agreement when it comes to comparison between model estimates and measurement in the actual system. Often this discrepancy is misunderstood as a lack of complexity and/or an incomplete formulation of the involved varied processes. But in this introduction to a debate it is argued that the explanation usually lies in the high complexity of the models in relation to the limited data available for the calibration of model constants. Two examples are given.
