Moquet Js., Morera S.B., Crave A., Vauchel P., Pombosa R., Lavado W.C., Guyot J.L., Martinez J.M.
Motivations Relationship Erosion vs weathering (silicate) in orogenic context
Integrator of critical zone behavior
Andes
Pacific Oceans
Characterisation of pacific river quality Mass balance budget to Pacific rivers
Low knowledge of Pacific solids and chemical inputs

Material and method
5 monitored stations (2008-2011-HYBAM) : - Daily discharge - 10 days frequency surface suspended matter concentration -Monthly major elements concentration
+ 14 discrete rivers sampling : Major elements Annual discharge (Lavado et al., 2012) Flux calculation (Concentration x discharge)
Material and method Distribution of daily discharge for suspended matter and dissolved solids sampling
Allows the estimation of annual suspended and dissolved matter fluxes
