Hi Amit Kumar; The following link will be of great help for you.

Good luck.

Maren Oelbermann

Check my home page or my website www.moelbermann.com under publications. I have three publications on CH4 and CO2 emissions from flooded reservoirs using soil with different C stocks. Note that these papers are based on soil incubations. My colleague Dr. Sherry Schiff at the University of Waterloo (Department of Earth and Environmental Sciences) and her research team evaluated CO2 and CH4 fluxes from reservoirs. I am not sure however, if these were from sediment or the water surface, or both. You would have to check her website for publications (her former PhD student J. Venkiteswaran was working on this) or contact her. Also, in the past there has not been much concern with N2O emissions from reservoirs (at least 10+ years ago when I was involved in this work in northern Ontario, Canada -- Boreal forest). However, I recently read that there are now some potential N2O concerns. Hope this helps.
