- 17. Rivers broke their banks: the Don, the Sheaf, the Rother, the Ryton, the Hipper... Was this mainly a fluvial flooding event (from rivers) or a pluvial event (from rain)
- 18. What caused it ? 25 th of June: torrential rain fell over a large area: the equivalent of the contents of over 20 Olympic sized swimming pools every second fell on the city of Hull The 2 weeks before the 25 th were very wet, and the water table was close to the ground surface ( antecedent conditions ) Why so much rain ?

- 20. 20 - 30 000 feet high Jet Stream: aircraft pilots ‘Ribbon’ of wind – speeds of between 100 and 300 miles per hour Form where cold polar air meets warm tropical air. ‘Steer’ depressions What caused it ?
- 22. PFJS: moves from West to East Summer: normally veers North and leaves calmer HIGH pressure conditions over UK In 2007, Jet Stream stayed south What caused it ?
- 25. Why so much rain ? The polar jet which steers our weather system was stuck further south than usual for the time of year, so we were more open to low pressure systems Warm air, so more evaporation from ocean As a result, a month’s worth of rain fell in 24 hours in some parts of the country. Same again this year...
- 26. Why was this a hazard ? Something becomes a hazard when it does one or both of the following things: endangers life and damages property or the environment threatens human societies and their welfare

- 28. Hazard Risk Equation Hazard x Vulnerability Risk = Capacity
- 29. Primary or Secondary ? Primary : Immediate – as a direct consequence of the hazard Secondary : Follows later – an indirect (but connected) consequence of the hazard.

- 48. 12 months on… (June 2008) More than 10,000 people are still unable to return to their homes after last summer's flooding, figures obtained by BBC Radio 5 Live suggest. “ Councils in England confirmed around 5,000 households remained affected, but added many may not be on lists because they rented or stayed with relatives.” A shortage of skilled workers, as well as problems caused by a cool, wet winter have slowed down repairs. The worst affected area was Hull.
