Today, erosion of the eastern Andean cordillera and sub-Andean foothills supplies over 99% of the sediment load passing through the Amazon Basin. Denudation rates in the upper Ucayali basin are rapid, favoured by a marked seasonality in this region and extreme precipitation cells above sedimentary strata, uplifted during Neogene times by a still active sub-Andean tectonic thrust. Around 40% of those sediments are trapped in the Ucayali retro-foreland basin system. Recent advances in remote sensing for Amazonian large rivers now allow us to complete the ground hydrological data. In this work, we propose a first estimation of the erosion and sedimentation budget of the Ucayali River catchment, based on spatial and conventional HYBAM Observatory network. specialized SEDIMENTATION FLUVIATILE MATIERE EN SUSPENSION EROSION METHODOLOGIE TELEDETECTION ESTIMATION BASSIN VERSANT COURS D'EAU ANDES AMAZONIE PEROU 062MECEAU04 064SEDIM 068EROSOL Jun Xu Y. ed. edt IRD et al. auteur aut IRD 367 320-325 Wallingford AISH 2015 International Symposium on Sediment Dynamics from the Summit to the Sea : ICCE2014, La Nouvelle-Orléans (USA), 2014/12/11-14 367 https://www.documentation.ird.fr/hor/fdi:010070648 10.5194/piahs-367-320-2015 978-1-907161-45-2 [F B010070648] https://www.documentation.ird.fr/hor/fdi:010070648 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers17-08/010070648.pdf IRD - Base Horizon / Pleins textes 2017-08-07 2018-03-27 fdi:010070648 fre
