Making Geography Matter
GA 21 Conference – June 2010
Writing in Geography: Hull 2007 case
study
David Holmes – Geography Consultant and
Teacher at Queens College Taunton
Outline
• Importance of writing + numeracy in
geography
• Tips for improving literacy
• Flood Vulnerability in the UK
• Using the Hull flood �kit’ to produce a
variety of different writing formats.
Importance of literacy and numeracy
The Secondary National Strategy
continues to emphasise the need to
improve language and literacy across the
curriculum. Teaching geography students
to understand data and to express
themselves clearly in the written form is
key to success in our subject.
Successful geographers can interpret and
manage a range of information styles and
write for different audiences.
Use writing and literacy in geography to…..

Severity 1: large flood events: significant damage to structures or agriculture;
fatalities; and/or 10 -20 yr reported interval since the last similar event.
Severity 1.5: very large events: greater than 20 yr but less than 100 year
recurrence interval,
Severity 2: extreme events: with an estimated recurrence interval greater
than 100 years
Flood Magnitude =LOG(Duration, days x Severity x Affected Area, sq km )

Flooding in the UK
• Flash flood. (Term often misused by the media because it is
dramatic!). Flash floods are uncommon. Defined as “rainfall event
lasting for minutes (up to a maximum of 6 hours), of great
intensity, over a small area, giving almost instantaneous rise in
river level and rapid recession”. E.g. Boscastle.
• Single event flood. Much more common. Result from passage of
frontal weather system across broad area. Rainfall period
measured in hours/days, occurring over large regional scale. Large
river catchments often affected. (Eg Severn, Trent, Ouse,
Thames)

Hull – the Facts
• A notable feature of the June 25th 2007 floods in Hull was its
widespread nature:
• 8657 houses on more than 600 streets were flooded or damaged
by floodwater with over 20,000 people were affected. This is
approximately 8% per cent of the population within the area of
Hull City.
• 6300 people were forced to live in temporary accommodation
with over 1400 people in caravans; 1300 businesses were
affected.
• Schools were especially badly hit, 91 out of 99 affected. The
closure of schools can have a large social and economic effect,
forcing parents to take time off work, and lose earnings in some
cases.

Variation and complexity of vulnerability at the local
scale

North-south divide???
Hull received the
biggest intermediate
payout from
government aid aimed
at helping communities
recover from floods.
This perhaps shows how
the vulnerability of
people in Hull was
recognised at a
government level.
Was it the same for
media reporting?

Vulnerability
п‚— We have increased our vulnerability to river
floods in the UK in almost every conceivable
way in recent years.
п‚— River flood plain development.
п‚— Increased value of properties, infrastructure
and goods.
п‚— Increased reliance on flood prone
investments
п‚— Increased inter-dependency of local and
regional economies
п‚— Changes in agricultural practice (hedgerow
removal , deforestation, etc)
