AB: Frappart et al. (RSE, 2005) studied the floodplain volume variation
in the Rio Negro basin, using the sole TOPEX/POSEIDON (T/P) GDR's
data. In this study, river main stream and their linked floodplains could
not be separated, due to the course effective resolution of these data.
We have processed both data of ENVISAT RA2 altimeter, and retracked
T/P data. The T/P data have been retracked with three of the ENVISAT
trackers (Ocean, Ice1, Ice2). We present results of the comparison
between the capability of each sensor and tracker to discriminate small
water bodies including river main stream and floodplain. Using an
original 3D method for defining virtual stations, we computed time
series of water stage for each individual inundated area. This time
series evidence the great spatial variability of the hydrological cycle,
depending on the connection and the relative location between the
main stream and lakes.
