  abstract = {{G}lobal riverine carbon concentrations and fluxes have been impacted by climate and human-induced changes for many decades. {T}his paper aims to reconstruct the longterm carbon concentrations and carbon fluxes of the {R}ed {R}iver, a system under the coupled pressures of environmental change and human activity. {B}ased on (1) the relationships between particulate and dissolved organic carbon ({POC}, {DOC}) or dissolved inorganic carbon ({DIC}), and suspended sediments ({TSS}) or river water discharge and on (2) the available detailed historical records of river discharge and {TSS} concentration, the variations of the{R}ed {R}iver carbon concentration and flux were estimated for the period 1960-2015. {T}he results show that total carbon flux of the {R}ed {R}iver averaged 2555 +/- 639 kton{C} year(-1). {DIC} fluxes dominated total carbon fluxes, representing 64% of total, reflecting a strong weathering process from carbonate rocks in the upstream basin. {T}otal carbon fluxes significantly decreased from 2816 kton {C} year(-1) during the 1960s to 1372 kton {C} year(-1) during the 2010s and showed clear seasonal and spatial variations. {O}rganic carbon flux decreased in both quantity and proportion of the total carbon flux from 40.9% in 1960s to 14.9% in 2010s, reflecting the important impact of dam impoundment. {DIC} flux was also reduced over this period potentially as a consequence of carbonate precipitation in the irrigated, agricultural land and the reduction of the {R}ed {R}iver water discharge toward the sea. {T}hese decreases in {TSS} and carbon fluxes are probably partially responsible for different negatives impacts observed in the coastal zone.},
