  abstract = {{I}n a context of water scarcity in {P}eruvian {P}acific catchments as a crucial issue for {P}eru, added to the paucity of data availability, we propose a methodology that provides new perspectives for freshwater availability estimation as a base reference for unimpaired conditions. {U}nder those considerations, a regional discharge of 709 m(3)/s to the {P}acific {O}cean is estimated with a significant increasing trend of about 43 m(3)/s per decade over the 1970-2010 period. {T}o represent the multidecadal behaviour of freshwater runoff along the region, a regional runoff analysis is proposed based on hydrological modelling at annual and monthly time step for unimpaired conditions over the whole 1970-2010 period. {D}ifferential {S}plit-{S}ample {T}ests are used to assess the hydrological modelling robustness of the {GR}1{A} and {GR}2{M} conceptual lumped models, showing a satisfactory transposability from dry to wet years inside the thresholds defined for {N}ash-{S}utcliffe and bias criteria. {T}his allowed relating physical catchment characteristics with calibrated and validated model parameters, thus offering a regional perspective for dryland conditions in the study area (e.g., the anticlockwise hysteresis relationship found for seasonal precipitation-runoff relationship) as well as the impacts of climate variability and catchment characteristics.},
