  3. 3. Waterscape vulnerability: coupling human & natural systems Over the past decade, we’ve documented that glaciers are receding, transforming downstream hydrology • How much mass are the glaciers losing? • How is downstream hydrology changing in the watershed? • What impact does this have on people?

  12. 12. Hydro transformation: Passing “peak water” •Persistent & accelerating glacier loss = release of more water from storage •Temporary increase in discharge (Q) •Current decline in dry season flow probably began in 1970s •Deficit in seasonal & annual Q + increased & varied demand raises concerns for water quality
  13. 13. Rio Quilcay Glacier fed headwaters Melt routed through shallow wetlands Metamorphic sedimentary rocks, sulfide deposits Large pastureland and eventual municipal water supply How is water quality impacted along flow paths from headwaters?

  17. 17. Summary • We have used various integrated methods to show that glaciers are a small total contribution to water flow, but critical seasonally. • The Santa River and most tributaries have probably passed a critical threshold and are now decreasing dry-season flow – Once the glaciers completely melt, the discharge will be lower than present by 2-30% – Santa River could be on the high end of this estimate • Water quality is an emergent issue, with high metal concentrations (natural & anthropogenic sources) • >80% dry season discharge is extracted before Pacific – For industrial ag irrigation, municipal drinking water • Metal concentrations already threaten water quality in Peruvian glacial melt streams; natural (geology) + human activity
  18. 18. Key insights 1. Glacial melt buffering is scale dependent, and dynamic 2. Groundwater is the major component of the dry season discharge. Further work is required to constrain residence times, flow dynamics, pro- glacial wetland processes. 3. Systematic understanding requires an integration of sustainable embedded observations, modeling and social science, with open sharing of data. 4. Water quality is an emergent issue, with high metal concentrations (natural & anthropogenic sources)
