Our research and resulting impacts extend across a wide range of flooding problems, from localised urban floods to river bas in flooding. The under pinning research ranges from extending the evidence base, to improved rainfall estimates, and to advances in hydrological and hydraulic models. The impact of our research has been through the creation and application of new methodologies (e.g. AOFD) and software tools (e.g., TSRSim) for the design and analysis of flood management systems in the UK and internationally, via joint projects with consulting engineering companies, and through the influence of our research on national and regional policies towards improved land use management practices (e.g., Glastir, Wales).
Rapid runoff from rural parts of river catchments can pollute downstream water bodies by transmitting sediment, agricultural fertiliser, or other pollutants from extensive diffuse sources, and can also lead to downstream flooding. Environmental managers often try to mitigate these problems by encouraging interventions, such as changes in farming practice or the construction of physical obstacles, which delay runoff from rural catchments. DU geographers have worked with stakeholders to develop a family of flexible user-friendly computer modelling tools which predict and map the likely critical sources of pollution or flooding and the downstream locations that are most at risk. This helps environmental managers target the best locations for intervention and compare the effects of alternative interventions. The software tools have been used by regulatory bodies (e.g. the Environment Agency) and NGOs (e.g. Rivers Trusts) to plan mitigation works and benefit local communities and the environment in many parts of England.
Throughout the REF period our research - driven by risk assessment theory - has provided a continuously updated set of unique models, data and techniques for assessing the benefits of UK flood alleviation investment. These have been used to justify all flood alleviation investment for the whole of the UK for the whole of the REF period (c. £3bn), as well as for the previous 30 years. Our work has been central to all assessments by Defra and the Environment Agency (EA) of national flood risk (Foresight; NaFRA (England, Wales, and Scotland); LTIS) and all the Catchment Flood Management Plans for England and Wales. The research is also used in Scotland (by the Scottish Environmental Protection Agency, SEPA), by international and national insurers (e.g. through Risk Management Solutions Ltd), and in many other countries.
This research has demonstrated the effectiveness of an experimental method of public engagement - Competency Groups (CGs) - in situations in which the expertise involved in managing flood risk is called into question by the communities living with such risk. Working in two test areas (Ryedale, Yorkshire and the Uck catchment, Sussex) it has enabled novel research collaborations between scientists and concerned citizens that have generated bespoke flood models and new flood management options. The work of the Ryedale CG and the `upstream storage' proposals that it generated were incorporated into a successful multi-agency bid to a national competition launched by Defra for a project to test new flood management solutions for Pickering, and are now under construction in the catchment. Having become a national exemplar, the reach of the Competency Group approach in tackling public controversies about environmental expertise continues to extend beyond these two areas, within the UK and also abroad.
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.
This case study concerns the impact of interdisciplinary research on policies and practices to support river restoration and the aims of the European Water Framework Directive (WFD), which requires member states to bring riverine hydromorphology and ecology to 'good' status by 2015, measured against a reference condition. The research achieved impact through an evolving process of co-production, in that academics engaged with user communities from the outset. Richards, Hughes and Horn (Department of Geography, University of Cambridge) worked closely with users to design a knowledge transfer guidebook to communicate restoration science to users.
This was distributed amongst Environment Agency (EA) staff to aid the planning and implementation of restoration projects. Further impacts included promoting floodplain restoration for flood risk management (Richards, as a member of an EA Regional Flood and Coastal Commitee); a rapid assessment method for river quality (Richards and Horn) that forms the basis of cross-boundary WFD compliance practices across the whole of Ireland; and knowledge transfer of EU WFD ecological assessment practices to China (Richards).
RVC's Veterinary Epidemiology, Economics and Public Health team (VEEPH) has been at the forefront of applying and evaluating new techniques for modelling disease risk, for policy and decision makers to use in surveillance and control of animal and zoonotic infections. Application of their recommendations, including European `Commission Decision' legislation, is contributing to ensuring that Europe remains free from African swine fever (ASF). The status of FAO Reference Centre in Veterinary Epidemiology, awarded by the United Nations' Food and Agriculture Organisation in 2012, recognises the RVC as a centre of excellence in this field and reinforces its role in guiding policies relating to animal health.
Statistical modelling of storms by Professor David Stephenson and co-workers in the mathematics institute at the U. of Exeter, has improved the understanding and thereby the pricing of insurance risk due to European windstorms and tropical cyclones. Temporal clustering in these catastrophic natural hazards has been quantified using novel process-based statistical models, which have then been implemented by industry to improve insurance pricing, e.g. on the integrated financial platform used by Willis actuaries to provide a more reliable view of risk as required by EU solvency 2 regulation. This research has also raised awareness in the industry about storm clustering, and has stimulated significant improvements in the main vendor catastrophe models, which are the main tools used by insurance companies to price European windstorm insurance.
Research at Newcastle University into stochastic rainfall models and their application has transformed the practice of impact assessment of climate change and risk assessment of environmental hazards across multiple sectors. The Newcastle methods underpin the "Weather Generator", a web-based tool which has been made available since 2009 by DEFRA as part of their official UK Climate Projections (UKCP09). The tool's incorporation into this official data source means that the models generated underpin multi-sectoral risk assessment throughout the UK and subsequently have led to the adoption of stochastic methods in general, particularly in the water and insurance industries to produce more robust risk assessments.
The Hydro-environmental Research Centre (HRC) at Cardiff University has developed a widely used hydro-environmental numerical model, called DIVAST (Depth Integrated Velocities And Solute Transport). DIVAST addresses the need for more accurate models to predict flood risk and water quality levels for a range of extreme events. The model has been implemented in commercial codes, marketed by CH2M HILL (previously Halcrow), and used in design studies, for example, undertaken by Buro Happold. The impacts of the research are marked environmental, health, economic and industrial benefits. It is used by major organisations around the world on large-scale projects and, in particular, for mitigation planning against national and international risks associated with floods and water quality.
