Climate change impact on hydropower production
This figure shows a general methodology applied to model the impacts of climate change on hydropower production. According to this figure, the quantification of climate change impacts on hydropower production is achieved by two main steps: (1) Generate the multi-GCM and multi-scenario projections of daily inflows into the selected hydropower dams; (2) Produce the multi-GCM and multi-scenario projections of hydropower production for all of the selected dams.
