Workshop results
Higher number of hazards Increased danger because of settlements in
mountainous regions• Examples of hazards:
• Debris flow, outburst of moraine-dammed lakes
Workshop results
High hydrological significance of mountains• Great amount of river runoff is formed in the
mountains
• Summer peak because of snow and glacier melting
• Especially important in arid regions
• Problems of water supply in these regions because of climate change (glacier melting, less precipitation)
Negative effect of climate change on hydropower as a consequence of changes in river discharge
Thanks for your attention!
