We illustrate this for the Amazon basin, in the area of upper Rio Madeira, where the inundation risk increased recently on populations downstream because of changes in the local economy. With use of satellite altimetry, the hydrological relationship between the main stem and the related water bodies that cyclically retain and liberate large amounts of water can be explained with sufficient details to aid in risk mitigation. specialized Hydrology satellite altimetry ungauged basins 062 126 32 3 303-319 2009 0149-0419 https://www.documentation.ird.fr/hor/fdi:010059104 10.1080/01490410903094809 0149-0419 [F B010059104] https://www.documentation.ird.fr/hor/fdi:010059104 https://www.documentation.ird.fr/intranet/publi/depot/2013-05-29/010059104.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2009-11-09 2017-08-23 fdi:010059104 fre
