Our objectives and supporting research questions are:
1. To simulate future climate and glacier recession and their impact on mountain environments (Challenge 1)
- How will temperature and precipitation evolve on an individual catchment scale in this complex mountain terrain?
- At what rate will glaciers recede into the future?
- What will the resulting landscape look like, and where and when will new lakes emerge?
- How will freezing levels evolve with different warming scenarios?
2. Measure and forecast changes in sediment flux/delivery to downstream areas (Challenge 3)
- What are the rates of sediment release by glaciers in active recession?
- What is the current capacity of lakes to store sediments released by glacier recession?
- Are contemporary rates of sedimentation comparable with those of the recent past?
- How will downstream fluvial reaches be impacted by changing sediment dynamics brought about by deglaciation and lake development?
3. Assess future risks presented by glacial lakes and ice/rock avalanches (Challenge 5)
- Where will the major hazards be located and what are their likely triggers?
- Will the most vulnerable people, defined by socio-economic factors, be located in zones that may be impacted by these hazards?
- To what extent will major flood events entrain downstream debris and how will this impact on flood propagation?
- Are planned infrastructure projects e.g. hydropower developments, likely to be in zones that may be impacted by glacier hazard and water scarcity events?
4. Balance risks and resources: integrating recommendations for businesses, policy makers and people (Challenges 1, 3 and 5)
- Which future lake sites will have the most sustainable water supply and minimum potential for sedimentation and over what timescale?
- What are the cultural, social and economic pressures that may be in conflict when creating natural water storage areas in the mountain landscape?
- What is the current political context for water storage and exploitation and how may relevant policies account for changes in glacial runoff and landscape evolution?
- What are the opportunities for resource exploitation in the context of future environmental change?
