dc.descriptionOriginal abstract: Discharge measurements, precipitation observations and hydrochemical samples from catchments of the Callejon de Huaylas watershed draining the Cordillera Blanca to the Rio Santa, Peru, facilitate estimating the glacier meltwater contribution to streamflow over different spatial scales using water balance and end-member mixing computations. A monthly water balance of the Yanamarey Glacier catchment shows elevated annual discharge over December 2001–July 2004 compared to 1998–1999, with net glacier mass loss in all months. Glacial melt now accounts for an estimated 58% of annual mean discharge, 23% greater than 1998–1999. At Lake Querococha, below Yanamarey (3.4% glacierized), a hydrochemical end-member mixing model estimates that 50% of the streamflow is derived from the glacier catchment. Average concentrations from the Rio Santa leaving the Callejon de Huaylas (8% glacierized) are modelled as a mixture with 66% deriving from glacierized tributaries of the Cordillera Blanca as opposed to the non-glacierized Cordillera Negra end member.es_PE

dc.description.abstractSeñala que las mediciones de descarga, las observaciones de precipitación y las muestras hidroquímicas de las cuencas de la cuenca del Callejón de Huaylas que drenan la Cordillera Blanca hasta el Río Santa, Perú, facilitan la estimación de la contribución del agua de deshielo del glaciar al flujo de la corriente en diferentes escalas espaciales utilizando el balance de agua y los cálculos de mezcla del miembro final. Asimismo menciona que un balance de agua mensual de la cuenca del glaciar Yanamarey muestra una descarga anual elevada entre diciembre de 2001 y julio de 2004 en comparación con 1998-1999, con una pérdida neta de masa de glaciares en todos los meses.es_PE
