Summary of the impact
Thorne's research for the Flood Foresight project changed UK policy
towards sustainable Integrated Flood Risk Management (IFRM), as
implemented by the Floods and Water Management Act (2010). This
legislation introduced new systems of governance to clarify
responsibilities, support co-ordinated actions, strengthen the roles of
local stakeholders, foster the co-production of knowledge, and work with
natural processes. Flood Foresight has attracted international attention
and stimulated projects and policy changes elsewhere, including in the
Taihu Basin in China and around the city of Gold Coast in Queensland,
Australia.
Underpinning research
Research by Thorne (Professor of Physical Geography) on flood risk and
flood policy was completed as part of the Flood Foresight project
commissioned in 2002 by Sir David King, the UK Government's Chief
Scientific Advisor. The project was a response to unprecedented flooding
in 1998 and 2000 and predictions that future flood damage will increase
due to climate change and poorly planned urban development. The government
accepted Flood Foresight's headline message that increasing flood risk
represents a major challenge to UK civil society and that `business as
usual' is no longer an option.
Flood Foresight drew on an international team of nearly 90 experts. The
aim was to challenge existing flood risk management practices. The
objective was a 30-100 year vision for the future of flood and coastal
defence in the UK that considers uncertainties and can inform national
policy. Thorne led the `Rivers and Environment' group and oversaw the
qualitative assessment of future flood risk. He investigated the
contribution that working with natural processes can make to managing
future increases in flood severity in a sustainable way. He edited the
Flood Foresight volume (1), co-authored five of its chapters, co-authored
the main reports presented to government (2 and 3), and published aspects
of this work in a peer reviewed journal (4).
Thorne developed innovative approaches to the assessment and ranking of
future flood risks which were refined and applied across a range of
potential responses to increasing flood risk. He established the
importance of properly aligning flood risk and environmental regulation to
avoid conflicting river and coastal management actions that would
otherwise amplify future flood risk. His key findings are that a
co-ordinated portfolio of structural and non-structural measures are
necessary to keep flood risks at current levels; that it is essential to
work with natural processes wherever possible; and that decision-making
and governance are of primary importance to reducing future UK flood risks
sustainably.
In 2008, Flood Foresight was updated as part of the Pitt Review, an
independent government review following the summer 2007 floods. Thorne was
the Principal Investigator on the Pitt Review and was responsible for
reviewing and updating the qualitative assessment of future flood risks
and responses related to river morphology and sediment supply,
environmental regulation and river vegetation and conveyance (5).
Between 2006 and 2009, Thorne was Principal Investigator on a three-year
project that adapted Flood Foresight approaches for the Taihu Basin in
China. His research involved characterising, assessing and accounting for
flood risks related to sediment, debris and geomorphology and identifying
how these risks can be managed sustainably (6). In 2010, the Environment
Agency of England and Wales (EA) commissioned Thorne to synthesise and
transfer knowledge on qualitative assessment developed in China back to
the UK.
Flood Foresight involved two other researchers based at Nottingham at the
time: Charlton (Lecturer in Physical Geography and Research Associate
2003-4) who contributed to the 2004 reports (2, 3), and Harvey (Research
Associate and Project Administrator for the Taihu Basin Study 2006-9) (6).

Details of the impact
Flood Foresight established a radically different approach to the study
of future flood risks and their management, based on a long-term
examination of the entire UK flooding system. Effective stakeholder
engagement was crucial to achieving the aims of Flood Foresight and was
delivered through `buy-in' workshops organised by Thorne. Research
outcomes were targeted to government, policy makers and technical
specialists with the aid of a science writer. The findings led to a
significant shift in UK flood risk management, enacted by the Floods and
Water Management Act 2010 (a). The Act includes multiple recommendations
from Flood Foresight, several stemming specifically from Thorne's
research. These include accounting for environmental as well social and
economic flood risks, and working with natural processes. Implementation
of the 2010 Act changes and clarifies the responsibilities of different
parties, supports co-ordinated actions, strengthens the roles of local
stakeholders and fosters the co-production of knowledge related to IFRM.
Additionally, the management of flood risk is now better integrated with
environmental regulation, notably through the promotion of Natural Flood
Management in conjunction with conventional, structural and non-structural
solutions.
Flood Foresight, including Thorne's research, has informed government,
policy makers and implementing organisations at strategic and operational
levels, changing the framework of delivery of flood and coastal risk
management (g). It has directly improved the flood risk assessment
capabilities of the EA where a significant amount of current research has
its roots in Flood Foresight (g, h). The Director of Flood and Coastal
Risk Management at the EA summarised Flood Foresight research as "ground
breaking and world leading science", further explaining that "you
can go onto our website, you can type your postcode in and you'll see
whether you are in a floodplain or not, and you'll also be able to, by
a move of the mouse, determine what your level of risk is, and that is
using the science that was provided through the Foresight Project"
(f). The EA uses Flood Foresight research to quantify the impact of flood
risk and the costs of investment in reducing risk (h), and adopts this
approach in Thames Estuary 2100, its plan for protecting London
from flooding for the rest of this century (d, h).
The research continues to inform EA Flood and Coastal Erosion Risk
Management (FCERM) planning through the Future National Flood Risk
Assessment and Long term Investment Strategy. In relation to Thorne's
research on working with natural processes, the EA's Director of Flood and
Coastal Risk Management stated in 2013 that "a really good example
is the Steart Peninsula in Somerset where we are creating significant
intertidal habitat but at the same time... protecting a community that
is at risk of flooding and ... providing future compensatory habitat
for other works that may be needed in the Severn estuary" (f).
Flood Foresight, and the 2008 Flood Foresight Update, have significantly
influenced national policy on the management of flood risk across a range
of government departments and operating organisations (a, b and c). For
example, the Department for Environment Food and Rural Affairs (Defra) and
the Department for Communities and Local Government (DCLG) now ensure that
flood risk is fully taken into account at all stages in the planning
process. As a DCLG spokesperson has stated: "The [Flood Foresight]
report was very important in providing the justification for, and
setting the approach and scope of planning policy" (e).
Thorne's research impacts are felt beyond the UK and extend overseas.
According to the UK Government Office for Science, Flood Foresight's
principles have, for example, now been adopted more widely in China,
expanding the original impact on the Taihu Basin (h). The Director of the
Department of Water Hazard Research and Vice-Chief Engineer of the China
Institute of Water Resources and Hydropower Research states that: "the
value of the Flood Foresight study has been fully recognised and
highly appraised. That's why the [Chinese] government gives
continued support to such study in the 12th
five-year science and technology support plan." The Director
also states that "the significance of the [Taihu Basin] project is
[in] giving us a model and approach of scientific decision-making to
ensure sustainable development" (j).
Catastrophic flooding in Queensland, Australia, in 2011 has also prompted
a Flood Foresight mission in 2012, co-led by Thorne, and the Gold Coast
City Council has now developed its own Foresight-style scenario-based
planning approach (i).
