Systematic testing of an integrated systems model for coastal zone management using sensitivity and uncertainty analyses
Systematic
testing of integrated systems models is extremely important but its
difficulty is widely underestimated. The inherent complexity of the
integrated systems models, the philosophical debate about the model
validity and validation, the uncertainty in model inputs, parameters and
future context and the scarcity of field data complicate model
validation. This calls for a validation framework and procedures which
can identify the strengths and weaknesses of the model with the
available data from observations, the literature and experts' opinions.
This paper presents such a framework and the respective procedure. Three
tests, namely, Parameter-Verification, Behaviour-Anomaly and
Policy-Sensitivity are selected to test a Rapid assessment Model for
Coastal-zone Management (RaMCo). The Morris sensitivity analysis, a
simple expert elicitation technique and Monte Carlo uncertainty analysis
are used to facilitate these three tests. The usefulness of the
procedure is demonstrated for two examples. (C) 2006 Published by
