Abstract

Reasons for the inability to obtain unique and conceptually realistic parameter sets for conceptual rainfall-runoff models are examined. The problem is first posed in a framework that allows a more consistent and logical analysis of the related aspects. Response surface studies demonstrate that choice of an objective function that better explains some of the stochastic properties of the errors in the output results in a smoother, better shaped response surface; hence the chances of obtaining unique and realistic parameter estimates are improved.-from Authors
