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!
