| Zusammenfassung |
| The Yeso River system, a tributary of the Maipo River Basin, helps sustain water supply for
one third of Chile’s population and a multimillion-dollar agricultural industry. The hydrology
of these headwaters is strongly dominated by a host of cryospheric elements including
seasonal snow, permafrost, rock glaciers, and white as well as debris-covered glaciers. In this
research we investigate the hydrologic role of the debris-covered Piramide Glacier under
current and future climatic conditions through a monitoring and modeling effort, and
compare it with the behavior of the neighboring, uncovered, Bello and Yeso glaciers. This
presentation features data from the first of three monitoring seasons, and establishes
differences and similarities in streamflow variability patterns in relation to local meteorology.
Additionally, mass balance data inferred from ablation stakes is related to regional climatic
conditions, which were especially dry during the 2013 accumulation season in
central Chile, with the second driest year on record. The recorded information will be
employed for parameterization of debris-covered glacier mass balance models,
to be coupled with basin-wide hydrologic models for water resource assessment. |
