  abstract = {{H}ydro-sedimentology development is a great challenge in {P}eru due to limited data as well as sparse and confidential information. {T}his study aimed to quantify and to understand the suspended sediment yield from the west-central {A}ndes {M}ountains and to identify the main erosion-control factors and their relevance. {T}he {T}ablachaca {R}iver (3132 km(2)) and the {S}anta {R}iver (6815 km(2)), located in two adjacent {A}ndes catchments, showed similar statistical daily rainfall and discharge variability but large differences in specific suspended-sediment yield ({SSY}). {I}n order to investigate the main erosion factors, daily water discharge and suspended sediment concentration ({SSC}) datasets of the {S}anta and {T}ablachaca rivers were analysed. {M}ining activity in specific lithologies was identified as the major factor that controls the high {SSY} of the {T}ablachaca (2204 t km(2) yr(-1)), which is four times greater than the {S}anta's {SSY}. {T}hese results show that the analysis of control factors of regional {SSY} at the {A}ndes scale should be done carefully. {I}ndeed, spatial data at kilometric scale and also daily water discharge and {SSC} time series are needed to define the main erosion factors along the entire {A}ndean range.},
