摘要
One of the water resources modeling requirements is sufficient knowledge of long-term series of meteorological and hydrological parameters especially normal discharge in structural position and specific points of the basin. In this study, based on the nearest neighbor resampling method, a non-parametric model has been developed for a contemporaneous and correlated series simulation. To evaluate the performance of the developed model, hydrological basin time series of the Sirwan River located in west of Iran were simulated. The results obtained from the developed model were compared with the results of parametric models, PARMA and MPAR. Assessment of the compared results showed that the developed model had a better efficiency and performance in simulating time series than the parametric models. Also, the simulated time series statistical characteristics had a better conformity with the observed time series. Moreover, simulated time series with the concern of climate scenarios, e.g., increase or decrease annual discharge, showed that the developed model had a good efficiency in considering these changes and effects in time series simulation.
