A new modelling framework to assess biogenic GHG emissions from reservoirs: The G-res tool

Human-made reservoirs are now recognized as potentially significant sources of greenhouse gases, comparable to other anthropogenic sources, yet efforts estimate these reservoir emissions have been hampered by the complexity underlying processes and a lack coherent budgeting approaches. Here we present unique modelling framework, G-res Tool, which was explicitly designed net C footprint across globe. The framework involves development statistically robust empirical models describing four major emission pathways for carbon-based gases (GHG) from reservoirs: diffusive CO2 CH4 emissions, bubbling surface, due degassing downstream reservoir, based on an extensive meta-analysis published data past three decades. These allow prediction reservoir-specific how they may shift over time account naturally occurring GHG generating in aquatic networks.
