DESCRIPTION:This seminar given by Michel Baraër (hydrology professor at the
  École de technologie Superieure\, Montreal)\, is open to the public.   Gl
 acier shrinkage caused by climate change is likely to trigger diminished a
 nd less consistent stream flow in glacier-fed watersheds worldwide. In the
  tropical Andes\, where this retreat is particularly pronounced\, the hydr
 ological changes could generate problems for agriculture\, irrigation\, hy
 dropower\, subsistence farming\, livelihoods\, and tourism economies. Desp
 ite the threat posed by ongoing tropical glacier decline\, detailed studie
 s of the future impact of global warming on water resources in potentially
  affected regions are long overdue. After a brief overview of the current 
 regional situation\, we will explore the particular case of the Rio Santa 
 watershed in Peru. The Rio Santa drains the western slopes of the glacieri
 zed Cordillera Blanca in Peru and supplies fresh water to a large array of
  user types\, making an excellent site for studying regional water resourc
 es questions. We will detail how assimilation of observations from novel h
 igh resolution discharge recordings\, basin-scale hydrochemical characteri
 zation\, and model simulations of progressive glacier loss\, indicate that
  the Santa River has likely passed the transient “peak water” caused as di
 scharge from melting glacier storage provided higher flows. We will examin
 e maps of Rio Santa dry-season specific discharge projections that have be
 en established based on the recent Trans-disciplinary Andean Research Netw
 ork (TARN) field campaigns. These maps provide new insights on the Rio San
 ta watershed future evolution of water resources. Among other\, they show 
 a probable negative impact of glaciers retreat on the quality of the Rio S
 anta water.   Michel Baraër is a professor in hydrology at the École de te
 chnologie Superieure\, Montreal. He received his undergraduate degree in C
 hemistry from the University of Strasbourg\, France\, Master in “Integrate
 d Water Resources Management” from the Department of Bioresources Engineer
 ing at McGill\, and PhD in Earth and Planetary sciences also from McGill.
