摘要
This paper discusses the development and application of a technique which permits the analysis and improvement of hydrological models for the management of water resources of complex systems. Considering that such models are intended for practical application, the model was applied to the conditions of the Bolivian highlands. The model consisted of a deterministic part (HEC-1 model) linked to a stochastic component. The experience acquired indicated the possibility of adapting a more general procedure to compensate for the lack of rigour in the homoscedastic and independence hypothesis of the residuals. Use of this concept improved the estimation accuracy of the parameters and provided independent residuals with constant variance. A Box-Cox transformation was used to stabilize error variance and an autoregressive model was used to remove autocorrelation in the residuals.
