New approaches to analysing and modelling water systems, developed at Cardiff, have driven national policy changes to improve the proportion of fully functioning water ecosystems in the UK. UK Government, Welsh Government and a range of NGOs have adopted these new approaches, which replace traditional descriptive methods with experimental, analytical and modeling techniques for understanding water ecosystems.
These approaches have been used to develop the water-related component of the National Ecosystem Assessment. This document has directly impacted on UK river management policy, forming the basis of two Defra White papers, `Natural Choice' and `Water for Life', underpinning Welsh Government's Natural Environment Framework and informing the work of a range of NGOs.
The primary mission of the Centre for River Ecosystem Science (CRESS: http://www.cress.stir.ac.uk/index.html) is to build and translate scientific evidence into advice to end-users and policy makers in river management, both nationally and internationally. Site-based advice, design and monitoring have been provided to 55 projects, including award-winning river engineering schemes. Independently, our research in community ecology, fluvial geomorphology and agricultural pollutants has supported an outstanding contribution to the UKs response to the key EU Environmental Directives — Water Framework, Flooding, Species & Habitats and Bathing Waters. We have developed the official tools that are now used to determine the status of freshwaters and structure catchment management plans, and trained others in their use, have pioneered risk assessments and modelling of nutrient, pathogen or carbon losses, publicised their effects, scoped mitigation options though engaging with end-users, and steered the pan-European comparison of bio-assessment methods that now underpins common water policy.
A team at Bristol University has played a central role in the development of new methods for assessing water quality in rivers and lakes. These are making it possible for the water industry to more reliably assess water quality and identify sites where remedial measures must be applied to meet the new standard of `good ecological status' as required by the European Union Water Framework Directive (WFD), which passed into UK law in 2003. The innovative, diatom-based tools were used in 2008 and 2009 to assess all targeted surface waters (rivers and lakes) in the UK and Ireland, leading to massive investment in infrastructure. This has opened up the prospect of higher quality water in lakes and rivers - something that the public and environmental organisations demand. Over the next few decades, the investment will bring an estimated benefit of £200 million to residents in England and Wales alone.
Fluvial geomorphology research at Loughborough University has impacted on the approaches and procedures of practitioners responsible for characterising and managing river-bed sediments. Dr Graham's research has underpinned the development to commercialisation of an automated method for measuring river-bed sediment size. The associated cost-saving benefits have had an international reach into field practice, demonstrated by non-academic software sales across Europe, North America and Australasia. Professor Rice's research has underpinned strategies focused on managing river sedimentation problems, as well as the design of new tools and adoption of new approaches, especially in the USA, aimed at better managing fish populations.
Research by Professor Wilby since 1993 has led to the development of regional climate modelling techniques, climate risk assessment frameworks, and adaptation planning approaches for long- lived water and energy infrastructure. Benefits were delivered through public domain software, practitioner training, and technical advice to policy-makers. This case study provides examples of impact conveyed via these services to national and international agencies, non-governmental organisations and commercial partners who are formulating strategies to manage exposure of their portfolios to climate risks. The work helped build technical capacities in climate risk management and adaptation options appraisal, particularly in vulnerable parts of Asia and the Middle East.
Research by the University of Southampton into river processes and restoration has contributed significantly to the adoption of fluvial geomorphology as a tool for river management. The research quantified for the first time, the cost of sediment management in rivers to the UK economy and environment, arguing that improvements could be achieved by applying fluvial geomorphology. The research developed new evidence, tools and training that were adopted by river management agencies and consultants for the scoping, assessment and planning of projects. This has resulted in cost-savings through reduced river maintenance, improved river environments, and the creation of a new employment market for graduates with geomorphological training.
Good quality water is essential for life on earth. The `Centre for Intelligent Environmental Systems' (CIES) has developed computer-based solutions for the assessment of river water quality by environmental agencies, working to improve the quality. CIES research has informed discussions and decisions of the UK Technical Advisory Group for the Water Framework Directive (UKTAG WFD). UKTAG WFD have selected the WHPT (Walley, Hawkes, Paisley & Trigg) method, for assessing river water quality throughout the UK, in the context of river management to meet the targets set in the Water Framework Directive (Directive 2000/60/EC from the European Union), which the UK government signed up to in 2000 (Beneficiaries: UKTAG WFD; Environment agencies; The public). Indirect impacts can also be attributed to CIES research, as it enables improvements of river quality, which triggers positive impacts on the natural environment, public health and quality of life (Beneficiaries: The public). CIES software has also been released to environment agency biologists as second opinion tools, thereby resulting in improved delivery of the public service provided by these biologists, when they use the software (Beneficiaries: Environment agencies; Environment agency biologists; The public).
This work helps the UK and Ireland fulfil their statutory duties to assess and improve the state of freshwater ecosystems. EU legislation requires all water bodies to be managed sustainably to achieve a state close to that of the water body in its natural state. Research in Geography at Newcastle has pioneered the use of diatoms (microscopic algae) in lakes and rivers to describe the ecological characteristics of this natural state and developed models and software that allow deviation from this state to be assessed. The model and database are used by all water agencies in the UK and Republic of Ireland to fulfil their statutory requirements and have led to new environmental standards that indicate that over 40% of the total length of UK rivers is at risk from elevated phosphorus concentrations.
The OPAL Water Centre at UCL, funded to a total of £732k, developed an innovative educational national water survey programme accessible to people of all ages and abilities, promoted especially within disadvantaged communities. Of the more than 45,000 participants, 17% were from 'hard to reach' communities. The Survey encouraged greater understanding of the aquatic environment through public participation in water quality and aquatic biodiversity assessment and used high-quality research to link the community, voluntary and statutory sectors by creating a channel through which locally derived information could lead to site-specific management as well as national and international policy.
Angela Gurnell's research on the geomorphology, hydrology and plant ecology of urban water courses has led to the development of important new tools for the biophysical assessment and improved management of urban rivers. Known as the Urban River Survey (URS), these tools are accessed by the Environment Agency and River Trusts across London, and their application is supported with workshops and guidance provided by Gurnell and her team. The URS has been used to deliver morphological quality indicators for rivers across London; to appraise river restoration schemes; to develop catchment management plans; and to assess long-term changes in rivers. It is currently being developed to quantify and set targets for river improvement schemes in relation to their impact on river ecosystem services. Gurnell's work has made a distinct contribution to urban river improvements in Britain and Europe, particularly through her leadership in developing a European framework for assessing hydromorphology.
