Method for estimating the highest specific methane flux from the surface of reservoirs

The paper summarizes the results of the database of changes in the specific methane flux at various types of water reservoirs in Russia, in which the authors participated. Measurements were carried out by the method of “floating chambers” in different periods of the annual hydro-ecological cycle. Comparison of the obtained data with the results of foreign experience is given. An approach to parameterization of specific methane flux for calculating the maximum possible methane emission from artificial reservoirs when developing quantitative quotas of greenhouse gas emissions is proposed. The estimation both in different phases of regime (stratification, homothermia) and for separate morphological parts of reservoirs differing in depth is offered.
