  abstract = {{T}he {R}ed {R}iver, draining a 169,000 km(2) watershed, is the second largest river in {V}iet {N}am and constitutes the main source of water for a large percentage of the population of {N}orth {V}iet {N}am. {H}ere we present the results of an investigation into the spatial distribution and temporal dynamics of particulate and dissolved organic carbon ({POC} and {DOC}, respectively) in the {R}ed {R}iver {B}asin. {POC} concentrations ranged from 0.24 to 5.80 mg {C} {L}-1 and {DOC} concentrations ranged from 0.26 to 5.39 mg {C} {L}-1. {T}he application of the {S}eneque/{R}iverstrahler model to monthly {POC} and {DOC} measurements showed that, in general, the model simulations of the temporal variations and spatial distribution of organic carbon ({OC}) concentration followed the observed trends. {T}hey also show the impact of high population densities (up to 994 inhab km(-2) in the delta area) on {OC} inputs in surface runoff from the different land use classes and from urban point sources. {A} budget of the main fluxes of {OC} in the whole river network, including diffuse inputs from soil leaching and runoff and point sources from urban centers, as well as algal net primary production and heterotrophic respiration was established using the model results. {I}t shows the predominantly heterotrophic character of the river system and provides an estimate of {CO}2 emissions from the river of 330 {G}g {C} year(-1). {T}his value is in reasonable agreement with the few available direct measurements of {CO}2 fluxes in the downstream part of the river network.},
