摘要：Under the climate change, the emission of Green house gases (GHG) like CO2and CH4from artificial reservoirs, especially, in tropics are resulting in the global warming. The CO2and CH4in hydropower reservoirs is produced due to decompositio n of organic matter at the bottom. To find out relationship between CO2/CH4emissions and water quality, 10 water quality parameters viz. temp, DO, COD, TDS, pH, TP, nitrite, phosphate, total alkalinity, conductivity measured in site I & site II of Oyun reservoir of Nigeria were collected from the literature. The analysis indicated that CO2emissions from the reservoir were, mainly, affected by pH, alkalinity and DO. CH4emissions are not found due to shallow nature of reservoir. It is also found that if the number of water quality parameter decreases, the value of R2also decreases. A deeper analysis of the relationship between the different parameters and GHG emissions using mini tab software and the multiple regression revealed that the R2>0.9 for site 1 and R2>0.8 for site II indicates that these correlations could be tentatively used to predict the emissions from Oyun reservoir in the future
