  abstract = {{W}e introduce here a model for calculating, for the first time, the annual material fluxes exported by the main tributaries of the {C}ongo {R}iver. {T}his model is based on a knowledge of the functioning of the main physiographic systems of the {C}ongo {R}iver basin. {F}or the {U}pper {C}ongo, {K}asai and major right-bank tributaries, we obtained a water flow values of 11.2, 10 and 8.8 l s(-1) km(-2) respectively, suspended matter values of 7.6, 8.9 and 5.1 t km(-2) year(-1) and total dissolved solid values of 16.4, 10 and 8.6 t km(-2) year(-1) respectively. {W}e investigated the role played by the main physiographic units in the dynamics of material transfers within this huge concentrically structured basin. {T}he belt of high ground covered by shrubby savanna supplies most of the suspended matter ({SM} = 24 mg l(-1) at {M}ongoumba on the {U}bangi {R}iver-200 km above the confluence with {C}ongo {R}iver and 32 mg l(-1) at {O}uesso on the {S}an-ha {R}iver) and of the total dissolved solids ({TDS} = 42 mg l(-1) at {M}ongoumba on the {U}bangi {R}iver and 41 mg l(-1) at {O}uesso on the {S}an-g-ha {R}iver). {T}he concentration of suspended matter is reduced by the waters of the '{C}uvette {C}entrale', a vast basin covered by rain forest ({SM} = 8 and {TDS} = 16 mg l(-1) for the {L}ikouala aux {H}erbes basin). {M}aterial export fluxes at the sub catchment {O}utlets range from 4 to 9 t km(-2) year(-1) for suspended matter and from 11 to 31 t km(-2) year(-1) for total dissolved material. i.e. {TDS} + {DOM} (dissolved organic matter). {T}he basin acts as a gigantic organic matter reservoir, which can produce 25 t km(-2) year(-1) of organic matter in the central flooded zone. {F}inally, the paper presents the first map of specific mechanical and chemical denuidation rates for the main sub catchments of the {C}ongo basin.},
