  abstract = {{T}he tropical glaciers of the {C}ordillera {B}lanca, {P}eru, are rapidly retreating, resulting in complex impacts on the hydrology of the upper {R}io {S}anta watershed. {T}he effect of this retreat on water resources is evaluated by analyzing historical and recent time series of daily discharge at nine measurement points. {U}sing the {M}ann-{K}endall nonparametric statistical test, the significance of trends in three hydrograph parameters was studied. {R}esults are interpreted using synthetic time series generated from a hydrologic model that calculates hydrographs based on glacier retreat sequences. {T}he results suggest that seven of the nine study watersheds have probably crossed a critical transition point, and now exhibit decreasing dry-season discharge. {O}ur results suggest also that once the glaciers completely melt, annual discharge will be lower than present by 2-30% depending on the watershed. {T}he retreat influence on discharge will be more pronounced during the dry season than at other periods of the year. {A}t {L}a {B}alsa, which measures discharge from the upper {R}io {S}anta, the glacier retreat could lead to a decrease in dry-season average discharge of 30%.},
