Topic Video for AQA GCSE Geography: Managing Extreme Weather in the UK (Weather Hazards 13)

This topic video looks at different ways that are used to manage extreme weather events in the UK, including the role played by the Environment Agency, the Meteorological Office, local councils, transport companies and various charity groups.

It is part of the AQA GCSE Geography course - Paper 1: Unit A - The Challenge of Natural Hazards.

1. Flood Management in the UK:
   • The Thames Barrier, installed in 1982 at a cost of £534 million, is a significant measure to prevent storm surges in London, protecting 125 square kilometers of Central London from tidal flooding.
   • The Environment Agency oversees flood management in the UK, constantly monitoring ground moisture levels in river basins to predict and warn about potential flood events, allowing residents to evacuate if necessary.
   • Insurance agreements between the government and companies result in higher premiums for new properties on floodplains, discouraging construction in high-risk areas.
2. Managing Strong Winds and Storms:
   • The UK Met Office utilizes advanced technology for accurate weather predictions, allowing for early warnings and preparedness against severe storms.
   • Media technology advancements enable widespread dissemination of weather warnings through online platforms, ensuring people receive timely information on severe weather conditions.
   • Travel companies use these warnings to cancel services during extreme weather, minimizing risks to customer safety.
3. Drought Management in 2022:
   • During drought conditions, water companies can enforce hosepipe bans to prevent non-essential water usage, with fines for breaches.
   • Water companies may apply for official drought orders from the government, leading to water supply interruptions and public use of standpipes.
   • Water meters, widespread in the UK, charge households for their water usage, encouraging conservation efforts.
4. Extreme Heat Management:
   • In times of extreme heat, travel restrictions may be imposed due to tarmac and railway line issues, and some events, like sports fixtures, may be canceled.
   • Water companies invest in pipe networks to reduce water leakages during extreme conditions.
5. Handling Plummeting Temperatures:
   • Local councils are responsible for road safety during winter, employing gritters to salt major roads and plows to clear heavy snowfall.
   • Schools and businesses may close temporarily during major snowfall, depending on the status of local transport services.
   • Cold weather warnings from national organizations prompt individuals to take extra care, with charities supporting vulnerable populations during extreme cold, such as the isolated elderly and the homeless.
