FERNANDES, Renato de Oliveira; SILVEIRA, Cleiton da Silva; STUDART, Ticiana Marinho de Carvalho  e  SOUZA FILHO, Francisco de Assis de. Reservoir yield intercomparison of large dams in Jaguaribe Basin-CE in climate change scenarios. RBRH [online]. 2017, vol.22, e11.  Epub 20-Abr-2017. ISSN 2318-0331.  http://dx.doi.org/10.1590/2318-0331.011716033.

Climate changes can have different impacts on water resources. Strategies to adapt to climate changes depend on impact studies. In this context, this study aimed to estimate the impact that changes in precipitation, projected by Global Circulation Models (GCMs) in the fifth report by the Intergovernmental Panel on Climate Change (IPCC-AR5) may cause on reservoir yield (Q90) of large reservoirs (Castanhão and Banabuiú), located in the Jaguaribe River Basin, Ceará. The rainfall data are from 20 GCMs using two greenhouse gas scenarios (RCP4.5 and RCP8.5). The precipitation projections were used as input data for the rainfall-runoff model (SMAP) and, after the reservoirs’ inflow generation, the reservoir yields were simulated in the AcquaNet model, for the time periods of 2040-2069 and 2070-2099. The results were analyzed and presented a great divergence, in sign (increase or decrease) and in the magnitude of change of Q90. However, most Q90 projections indicated reduction in both reservoirs, for the two periods, especially at the end of the 21th century.
