Urban water systems have never been more strategically important - they are one of the key foundations of society. The reliable provision of safe drinking water and effective drainage and sewerage services is essential to us all. Society has developed an increased awareness of a number of environmental, social and economic issues associated with the provision of water services. Factors considered include the impacts of climate change, water scarcity, water security, flooding, drought, energy use, carbon footprint, environmental damage and impact on human health. These factors, combined with the fact that many of our existing urban water infrastructure systems are complex, old and deteriorating, creates significant new challenges for the water industry into the future. They also create significant new and exciting research challenges that the Pennine Water Group (PWG) at the Universities of Sheffield and Bradford is best placed to address.Historically the international reputation of the PWG has been built on delivering high quality scientific research that addresses the needs of the water industry. This has been achieved by taking a multi-disciplinary approach focused on urban water asset management. Our evolving vision for the future requires a transition to 'Sustainable Integrated Urban Water Systems' that 'move beyond the pipe' to a broader system definition. We propose to progress and deliver our future research at a range of scales and to integrate both man-made infrastructure and natural processes in large catchments within a holistic framework that incorporates technical, institutional, economic and cultural issues. This framework will be underpinned by new and novel scientific and technological advances but will involve the inclusion of a wide range of stakeholders. The platform grant renewal will support the transition from a multi-disciplinary to a trans-disciplinary group through fostering new inter-disciplinary research ideas combined with an ever more effective integration with industry and other stakeholders. This vision has 3 key development areas (1) Sustainable integrated systems and water sensitive urban design (2) Development and delivery of new technologies and (3) Implementation and governance.The new platform grant will be led by Prof. Saul with a core academic management team of Biggs, Boxall, Horoshenkov, Sharp and Tait. This team will be responsible for the delivery of the all fundamental science and outputs within the three key areas, but also for the monitoring of expenditure, developing future funding strategy, staff and career development and interactions with external stakeholders. The management group will seek support and guidance from both an Industrial Advisory Panel and an International Scientific Advisory Panel.A major strength of the existing PWG academic staff is their enthusiasm for collaboration and wider engagement across the RCUK disciplines. The new platform grant proposes to include four new academic colleagues, Lerner, Osborn, Beck and Molyneux-Hodgson, who will provide significant add-on technical expertise and with whom we are currently collaborating on funded projects. These staff will enhance the core skills of PWG, within a unique team, that will see significant and enhanced opportunities to stimulate and respond to new cross-discipline research ideas and initiatives. Following our successful existing practice, we will use the platform grant as a flexible resource to provide gap funding to support the future long term careers of our key researchers, to provide opportunities to visit overseas research groups and to present our work at major International Conferences. A point of specific importance is that the platform grant will allow the optimisation of the training, networking and mentoring afforded to all our researchers, and here, special emphasis will be given to the skills set required for a future academic career.

Project SINATRA responds to the NERC call for research on flooding from intense rainfall (FFIR) with a programme of focused research designed to advance general scientific understanding of the processes determining the probability, incidence, and impacts of FFIR. Such extreme rainfall events may only last for a few hours at most, but can generate terrifying and destructive floods. Their impact can be affected by a wide range factors (or processes) such as the location and intensity of the rainfall, the shape and steepness of the catchment it falls on, how much sediment is moved by the water and the vulnerability of the communities in the flood's path. Furthermore, FFIR are by their nature rapid, making it very difficult for researchers to 'capture' measurements during events. The complexity, speed and lack of field measurements on FFIR make it difficult to create computer models to predict flooding and often we are uncertain as to their accuracy. To address these issues, NERC launched the FFIR research programme. It aims to reduce the risks from surface water and flash floods by improving our identification and prediction of the meteorological (weather), hydrological (flooding) and hydro-morphological (sediment and debris moved by floods) processes that lead to FFIR. A major requirement of the programme is identifying how particular catchments may be vulnerable to FFIR, due to factors such as catchment area, shape, geology and soil type as well as land-use. Additionally, the catchments most susceptible to FFIR are often small and ungauged. Project SINATRA will address these issues in three stages: Firstly increasing our understanding of what factors cause FFIR and gathering new, high resolution measurements of FFIR; Secondly using this new understanding and data to improve models of FFIR so we can predict where they may happen - nationwide and; Third to use these new findings and predictions to provide the Environment Agency and over professionals with information and software they can use to manage FFIR, reducing their damage and impact to communities. In more detail, we will: 1. Enhance scientific understanding of the processes controlling FFIR, by- (a) assembling an archive of past FFIR events in Britain and their impacts, as a prerequisite for improving our ability to predict future occurrences of FFIR. (b) making real time observations of flooding during flood events as well as post-event surveys and historical event reconstruction, using fieldwork and crowd-sourcing methods. (c) characterising the physical drivers for UK summer flooding events by identifying the large-scale atmospheric conditions associated with FFIR events, and linking them to catchment type. 2. Develop improved computer modelling capability to predict FFIR processes, by- (a) employing an integrated catchment/urban scale modelling approach to FFIR at high spatial and temporal scales, modelling rapid catchment response to flash floods and their impacts in urban areas. (b) scaling up to larger catchments by improving the representation of fast riverine and surface water flooding and hydromorphic change (including debris flow) in regional scale models of FFIR. (c) improving the representation of FFIR in the JULES land surface model by integrating river routing and fast runoff processes, and performing assimilation of soil moisture and river discharge into the model run. 3. Translate these improvements in science into practical tools to inform the public more effectively, by- (a) developing tools to enable prediction of future FFIR impacts to support the Flood Forecasting Centre in issuing new 'impacts-based' warnings about their occurrence. (b) developing a FFIR analysis tool to assess risks associated with rare events in complex situations involving incomplete knowledge, analogous to those developed for safety assessment in radioactive waste management. In so doing SINATRA will achieve NERC's science goals for the FFIR programme.

The forecasting of marine weather, waves and tidal currents using models and in-situ measurements is vital for offshore operations and maintenance (O&M) in the marine infrastructure and marine renewable energy (MRE) sectors. Offshore O&M is limited by strict wave height thresholds at the offshore point of operations (typically 1.5m) and with the UK set to spend £2bn per annum by 2025 on O&M for the offshore wind industry alone the prediction of viable working windows for O&M is critical. In the tidal stream MRE sector the combined forces of waves and tidal currents on underwater tidal turbines can lead to dangerously high physical and electrical loads placed on equipment and infrastructure. Poor knowledge, and thus prediction of the local variability in weather, wave and tide conditions result in conservative thresholds for MRE operations. This, in turn, reduces the time MRE devices are in operation (and therefore energy generation), increasing investor risk and harming the financial development of the MRE sector as a whole. Existing wave and current monitoring and forecasting technologies rely on expensive in-situ measurements of the marine environment (e.g., floating wave buoys and devices on the sea bed) and models driven by these measurements or other large-scale simulations. Although very precise, the project partners have identified traditional wave and current monitoring techniques to be inadequate in terms of spatial coverage, timeliness and accuracy in complicated, high-energy coastal environments. These environments have previously proven to be difficult for wave and current observation and validation due to high equipment costs and risks of failure. As such there is a paucity of reliable, large-scale measurements of waves and currents in these high-energy marine environments. Marine navigational radar ('X-band') is a mature technology for the remote sensing of the marine environment, capable of generating estimates of tidal current speed, ocean wave parameters and water depths over wide areas. However the current state-of-the-art in X-band radar oceanography has been found lacking in the high-energy, dynamic and complicated coastal environments that marine energy projects are operating. This project aims to develop a step-change in the way we process radar data to generate measurements of the marine environment, paving the way for a system that can produce the environmental information the marine industry requires. NOC has a 20 year history at the forefront of marine radar oceanography and is well-placed to deliver this much needed development. To achieve this aim an open-source wave model will be integrated with the NOC's tried-and-tested radar analysis toolbox to produce a hybrid model/observation system. This system will combine modelled and observed wave information in such a way that minimises the errors in both; effectively generating a 'most likely' wave measurement over wider area every 10-15 minutes in near-real-time. The system will be developed using radar data and validated using ground-truth data recorded at the European Marine Energy Centre (EMEC) on Orkney; the world's largest and most successful MRE test facility. Once validated, the system will then be demonstrated in a real-world setting at the OpenHydro test platform at EMEC. This project includes researchers with expertise radar oceanography, marine observation and the numerical modelling of the marine environment. Our project partners include EMEC, the marine energy company OpenHydro and JBA consulting; a company at the cutting-edge of operational forecasting. This new and innovative environmental monitoring system will be developed with the guidance of our partners and the successful system used to supply the basis for high-impact solutions for the partners and their clients.

The need for a network of doctoral engineers with interdisciplinary skills: The UK leads the world in research, innovation, development, demonstration & deployment in wave and tidal technologies. It has 35% & 50% of European wave and tidal current energy potential respectively, and 13% of the shallow-water offshore wind potential. Existing offshore wind technologies could be used to meet 15% of UK electricity demand, with significantly greater potential available in deeper waters for new innovative technologies. The 2017 Digest of UK Energy Statistics shows that wind energy capacity is 16GW (with 5.3GW offshore). The UK has a greater installed capacity of tidal current technologies and has demonstrated a greater number of wave technologies than the rest of the world put together. UK and European offshore wind capacity is expected to increase, respectively by 1 and 2.5 GW/year until 2030. Bloomberg New Energy Finance have projected 115GW of global installed offshore energy capacity by 2030. Cambridge Econometrics have identified that to drive even just this UK development, by 2032, offshore wind would alone need to grow human capacity in the sector to around 60,000 FTE jobs in the UK, with 14,000 directly employed in managerial and professional engineering and scientific roles. The challenges to define and develop the necessary technologies and know-how for the ORE sector are defined by the interaction and inter-dependence of: impact on the natural environment; its energy resources; the emergence of new innovative technologies; manufacture, deployment, operation and maintenance at scale; micro- and macro-economic appraisal; regulation & policy; social & environmental acceptance. Prior experience in IDCORE and Supergen UKCMER, recent roadmaps, and advice from industrial partners show that we must train a connected network of scientists and engineers with deep use-inspired research & innovation skills in their individual domains, and an appreciation of the challenges and state of the art solutions across the breadth of the sector. The approach that will be taken: We propose to establish a new centre, building on the strengths of the successful Industrial Doctoral Centre for Offshore Renewable Energy and Supergen UKCMER. To exploit synergy, opportunities for scale & additional impact, this proposal is made in partnership by the Universities of Edinburgh, Exeter and Strathclyde and the Scottish Association for Marine Sceince. Together we will deliver and operate a fully integrated CDT forming a best-with-best partnership to create future leaders for the British energy systems and to train them to fully integrate offshore renewables into the decarbonised energy systems of the future. Specifically, the new IDCORE CDT will * Graduate 50 new postgraduate students, supervised by a cohort of over 80 academic staff in the UK. * Use world-class UKRI funded facilities to provide cutting-edge training in engineering, science & inter-disciplinary areas; * Deliver impact from excellent research in integrated cross-disciplinary themes from the ocean to the end user; * Train research students throughout the full life cycle of research, spanning theory to practice, including engineering, physical, data & natural science, economics, management, leadership & social-science skills. Overview of the research areas of the centre: Experience, assisted by our industrial partners, has defined the need for research, training and innovation in the following areas: natural resource; environmental impact assessment (and mitigation); development of offshore energy technologies; new materials and science for components, sub-systems and devices in the offshore environment; data science; autonomous inspection and condition monitoring; remote and local operation and maintenance; energy conversion, conditioning, storage and delivery; energy economics, policy and regulation. IDCORE provides this.
