Glacier Monitoring

"Despite typical glaciers’ massive sizes, monitoring them is not always an easy task. Only specific types of small glaciers are good measures of climate change. Some glaciers are too large to measure accurately, and others are simply too unpredictable. Once scientists find a suitable glacier, they must take satellite images of the ice for a minimum of five years and compare the results. They then have to look closely at the outside edge of the glacier (the glacier’s terminus). If a large percentage of the glacier’s edge is receding then the area around the ice is growing warmer, and if a large percentage is expanding then the area is growing cooler. When enough measurements from many different parts of the world have been gathered, the researchers can determine whether the earth is growing warmer or cooler" (NASA, 2018)

Space-based Solution

Collaborating actors (stakeholders, professionals, young professionals or Indigenous voices)
Suggested solution

Assessment of the challenge

  • Need more data about the location of the community and their usage of water
  • Split the challenge into a “glacier” and a down-stream challenge
  • No up-to-date weather data available since 2011
  • Discharge and temperature, rainfall and snow data available
  • Digital elevation surface and terrain model available

Outline steps to a solution & status

  1. Inventory of the snow cover and watershed area (completed)
  2. Build a regression model to assess the relationship between snow melt, temperature and discharge (to do)
  3. Hec-ras for flood modelling (to do)
  4. Use climate change projections to predict future discharge and flood extents (to do)
  5. Downstream impact analysis of hydro-power and agriculture (to do)
