Potential Evapotranspiration Methods for the Assessment of River Runoff under Climate Change

Based on an overview of the main potential evapotranspiration methods, the sensitivity of four potential evapotranspiration methods to temperature in three representative river basins of different climatic and hydrological natures was analyzed. With the application of the potential evapotranspiration methods in regional hydrological models, the impact of potential evapotranspiration methods on the assessment of river runoff under climate change was studied.
