  abstract = {{T}he fluvial transport and storage of sediments within channel-floodplain systems can act as important sinks of sediments. {I}n this study, we document the role of an {A}mazonian floodplain ({C}uruai) for sediment storage. {L}ocated on the right bank of the {A}mazon {R}iver, 900 km upstream of the mouth, the complex system contains more than 30 interconnected takes linked to the mainstream by permanent and temporary channels. {W}ith an open-water area varying between 600 km(2) and 2500 km(2), it represents similar to 13% of the total flooded area of the {A}mazon {R}iver, between {M}anaus and {O}bidos. {F}or the period 2000-2003, daily liquid and solid fluxes exchanged between the floodplain system and the {A}mazon {R}iver were determined using an hydrological model based on a network of gauging, meteorological and sediment monitoring stations and satellite data including radar altimetry data. {S}ediment accumulation occurs during the five months of the flood rise, from {D}ecember to {A}pril. {T}he export of sediments to the mainstream occurs during the low water stage while depositional processes in takes and channels are disrupted by the wind induced re-suspension of sediments. {T}he mean average sediment storage catculated varies between 558 and 828 x 10(3) t yr(-1) corresponding to 5.4 (+/- 19%) x 10(3) t km(-1) yr(-1) of sediment deposited along the 130 km reach between {J}uruti and {S}antarem. {T}his annual storage represents between 41% and 53% of the annual flux of sediments entering this floodplain through the main channels. {T}he associated mean specific sedimentation rate is similar to 517 (+/- 23%) t km(-2) yr(-1) leading to a sediment accretion rate of 1.6 mm yr(-1) + 23%.},
