OSTI ID:6417872
The objective of the research project was to investigate methods for improving the reliability of compartmental models such as conceptual rainfall-runoff models. The study focused on the structural nonidentifiability problems of such models that have been observed to cause severe parameter-estimation difficulties. In particular, the problems arising due to the threshold nature of some parameters were investigated. Three new mathematical procedures were developed. One is a new objective function for rainfall-runoff models that was developed using likelihood theory and based on the error structure arising due to the nonlinear nature of the rating curve.
