Abstract:Climate change impacts on river runoff are unavoidable under different periods of climatic conditions. Hydrological models can be used to assess climate change impacts on river runoff in future periods. Research has shown that both non-stationary and stationary hydrological models are widely used to simulate runoff under climate change impact. This study starts from the hypothesis which is that correlations between optimal model parameters and climatic characteristics may exist, and this can be used to estimate parameter values when applying nonstationary models. The goal of this study is to determine correlations between parameters and climatic characteristics, compare the simulation performance of a non-stationary model with regression equations and a stationary model , and assess climate change impact on runoff with both models in future periods.
