  abstract = {{T}he objective of this study is to derive the stage-discharge relationship for 21 "virtual gauge stations" located at the upper {N}egro {R}iver ({A}mazon {B}asin, {B}razil). {A} virtual station can be defined as any crossing of water body surface (i.e., large rivers) by radar altimeter satellite tracks. {R}ating curve parameters are estimated by fitting with a power law the temporal series of water surface attitude derived from satellite measurements and the discharge. {D}ischarges are calculated using {P}ro{GUM}, a flow routing model based on the {M}uskingum-{C}unge ({M}-{C}) approach considering a diffusion-cum-dynamic wave propagation [{L}eon, {J}.{G}., {B}onnet, {M}.{P}., {C}auhope, {M}., {C}almant, {S}., {S}eyler, {F}., submitted for publication. {D}istributed water flow estimates of the upper {N}egro {R}iver using a {M}uskingum-{C}unge routing model based on altimetric spatial data. {J}. {H}ydrol.]. {A}mong these parameters is the height of effective zero flow. {M}easured from the {WGS}84 ellipsoid used as reference, it is shown that the height of effective zero flow is a good proxy of the mean water depth from which bottom slope of the reaches can be computed and {M}anning roughness coefficients can be evaluated. {M}ean absolute difference lower than 1.1 m between estimated equivalent water depth and measured water depth indicates the good reliability of the method employed. {W}e computed the free surface water slope from {ENVISAT} altimetry data for dry and rainy seasons. {T}hese profiles are in good agreement with the bottom profile derived from the aforementioned water depths. {A}lso, the corresponding {M}anning coefficients are consistent-with the admitted ranges for natural channels with important flows (superficial width > 30.5 m [{C}how, {V}.{T}., 1959. {O}pen {C}hannel {H}ydraulics. {M}c{G}raw-{H}ill, {N}ew {Y}ork]) and irregular section.
