weather & climate challenges

• | impact of climate - rivers

  erosion rate

  • higher with greater discharge so rivers in wet climates will erode more material, making rivers wider
• | impact of climate - rivers

  weathering

  • greater, like freeze thaw weathering in cold climates
• | weather & climate challenges

  changing weather

  • increase in STORMS: more periods of heavy rainfall so more water flowing into rivers which then overflow
• | weather & climate challenges

  changing weather

  • increase of hot, dry weather: bakes upper soil so water runs off the surface, flowing into rivers and increasing discharge
• | weather & climate challenges

  changing weather

  • impermeable soil: snowmelt cant infiltrate & flows into rivers, increasing flood risk
