Short summary
Run-of-the-river (ROR) reservoirs have reduced flooded areas that maintain natural river characteristics; however, little is known about their influence on carbon dioxide (CO2) emission. In this regard, we evaluated the spatiotemporal CO2 fluxes (FCO2) and partial CO2 pressure (pCO2) of the Belo Monte hydropower complex. Our results emphasize that ROR dams contribute to CO2) emissions. Only FCO2 varies through reservoirs; in addition, both FCO2 and pCO2 are spatially heterogeneous.
