IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

missions (GHGs) in reservoirs, notably methane (CH4) and carbon dioxide (CO2) have been focus of intense research in the last decade, focused on measuring fluxes of these gases, mainly at air-water interface. Within this context, this paper presents a zero-dimensional mathematical model capable of estimating the carbon balance in the reservoir considering the dynamics of organic and inorganic carbon, considering their dissolved and particulate fractions, interactions with the sediment and the influence of meteorological and hydrological forcings. The model also estimates diffusive and bubbling fluxes of CH4 and CO2. The case study is the Capivari Reservoir (ParanŠ, South Brazil) a 45 years old reservoir. The results indicate a mean methane emission over 43 years of simulation of 27.41 mgCH4m−2d−1 while the reservoir storage carbon at a rate of 720 mgCm−2d−1. The Capivari Reservoir emits CH4 but stores carbon at a higher rate so it attenuates greenhouse effect by an equivalent absorption of 529.3 mgCO2eqm−2d−1.Form Required :
