Summary

Floodplain hydrology regulates soil carbon dynamics and is a key factor in ecosystem restoration strategies for climate regulation. In Belgium, floodplains have been extensively modified by drainage and land-use change, yet the combined effects of hydrology, land use, and soil carbon quality on greenhouse gas (GHG) fluxes remain unclear. In the Dijle valley, located in central Belgium within the Belgian loess belt, we conducted a comprehensive study combining in situ GHG flux measurements with soil carbon quality characterization.We measured soil carbon dioxide (CO2) and methane (CH4) fluxes during the wettest year on record across three hydrological zones: (i) a moderately drained floodplain with fluctuating water table (Fluctuating WT), (ii) a poorly drained floodplain with shallower wat
