Analysis of objective functions used in urban runoff models |
|
| Authors: | A Ramachandra Rao |
| Abstract: | The objective functions used in parameter estimation in urban runoff models are compared by using a method proposed by Diskin and Simon1 and the urban runoff model ILLUDAS. Two sets of objective functions, the first one used by Diskin and Simon in their study and a second one which includes other objective functions are used. Rainfall-runoff data from urban watersheds in the US are used in the study. The results indicate that the least squares criterion is the best among those studied. |
