Step 1: Topography and meteorological data are input into the WEP-L model to simulate the hydrological process of the YT river basin. The model parameters are then calibrated based on the observed discharge, glacier mass balance and snow cover data. Step 2: Meteorological data under future climate scenarios are input into the WEP-L model to simulate future hydrological processes in the basin. Step 3: Under the constraints of the cascade reservoir scheduling rules and the “Water-Energy-Ecosystem” objectives, the NSGA-III model runs to reveal the changes in the WEE nexus under different climate-forcing scenarios. Step 4: The performance and changing patterns of the three objectives under various scenarios are analyzed.
