英文摘要Study region: Lancang-Mekong River Basin (LMRB) Study focus: Physics-based hydrological models are commonly employed to disentangle the effects of climatic and human factors on streamflow changes. To improve streamflow simulation performance, this study, tests the ability of a hybrid-physics-data (HPD) model that combines VICCaMa-Flood with Long Short-Term Memory (LSTM), to assess the relative contributions to the streamflow and floods in the LMRB during 1966-2015. New hydrological insights for the region: Streamflow and floods are mainly affected by climatic change during the transition period (1993-2007). The relative contribution of human activities ranges from 42 % to 91 % in the dry season and from 38 % to 82 % in the wet season in the postimpact period (2008-2015), outweighing the influence of climatic change. Additionally, human activities lead to a decrease in streamflow by -6 % to -24 % in the wet season, whereas causing an increase of 7-39 % in the dry season. While climatic change may increase flood magnitude by up to 21 % and increase flood frequency by up to 1.88 events per year, the observed flood characteristics are significantly lower than the HPD simulated changes, suggesting that flooding has been notably mitigated during the post-impact period due to human activities. The decrease in flooding in the downstream is mainly due to human activities, and in the upstream, is due to climatic change in addition to human activities.
