Modeling sediment diagenesis processes on riverbed to better quantify aquatic carbon fluxes and stocks in a small watershed of the Mid-Atlantic region

Table 4 Average annual POC and DOC fluxes from terrestrial to aquatic environments in the study watershed summarized over 2014-2017

Variable	Watershed contri.	Riverine contri.	Outlet outflow	Deposition	Resuspension	Net deposition	Bury
POC (kgC ha⁻¹)	36.6	0.05	24.5	11.44	0.04	11.4	0.34
DOC (kgC ha⁻¹)	46	0.72	46.3	–	–	–	–

	Out/WC	NDep/WC	NDep/Out	Res/Dep	Bury/WC	Bury/Out	Bury/NDep
POC	0.67	0.31	0.47	0.004	0.009	0.014	0.03
DOC	1.01	–	–	–	–	–	–

The table also includes average annual deposition and resuspension amounts of POC over the entire watershed and ratios between fluxes for POC and DOC
Out, WC, Dep, Res, and NDep indicate outlet outflow, watershed contribution, deposition, resuspension, and net deposition (equal to deposition–resuspension), respectively
