“Optimisation of ocean-powered turbines for seawater desalination”
In this webinar, Mohammad Hassan will present a novel conceptual desalination system, which can be powered by Horizontal Axis Tidal (HAT) and Vertical Axis Tidal (VAT) turbines. The energy required for desalinating 1 m3/h is determined and accordingly, a VAT turbine and a HAT turbine are separately designed to fulfil this amount of energy. The greatest weakness of these turbines is the high price of design, development, and manufacturing. Traditionally, optimisation of turbine geometry is achieved by running several numerical models of the turbine which can become computationally expensive. In this work, a combination of the Taguchi method and CFD modelling is used as a straightforward solution for optimisation of geometry of tidal turbines.

Assessment of urban water security in sub-Saharan African Capitals
Africa is facing big challenges by demographic development and climate change. It is expected that the African population will double between now and 2050. African cities will grow exponentially towards 1 billion inhabitants by 2050. This is an extremely challenging situation, that needs urgent and adequate response. Since 2019, WIRC @ Bath, KWR Water Research Institute and UNESCO are working with local young water professionals and MSc students from Bath to assess water security in African capitals. We use the City Blueprint Approach to develop a baseline assessment of the cities’ water management and governance performance. The young water professionals will communicate the outcome to the local water authorities and stakeholders and create a bottom-up approach to improve water security in the cities, for which they receive top-down support through UNESCO. Moreover, the young professionals form an expanding network where they can share experiences and best practices. In this way we contribute to capacity building, but also knowledge exchange between the cities can be realised. The presentation will give an overview of the City Blueprint Approach and its application in African capitals.
About Prof Jan Hofman
Prof. Jan Hofman is the Director of the Water Innovation and Research Centre and Professor on Water Science and Engineering in the Department of Chemical Engineering since 2015.

Westcountry Rivers Trust
9th July 2021
Evidence-based co-design, co-creation and evaluation of nature-based solutions, ecosystem restoration and systems change
Westcountry Rivers Trust (WRT – www.wrt.org.uk) is an environmental charity based in the South West of England that uses local, regional and national data together with stakeholder engagement to understand the evidence available and to effectively guide targeted catchment management delivery. Our core ethos revolves around a desire for balanced ecosystems, which may be achieved through conservation actions based on sound science, linked to engagement and education at all levels. WRT have been delivering practical environmental improvements to enhance ecosystem service provision and improve the ecological condition of rivers and catchment landscapes across the South West for 25 years.
WRT have spent >20 years developing a robust evidence-base to establishes a link between the processes that are occurring in catchments, the observed/recorded degradation of ecosystems/natural capital assets in a catchment landscape and the impacts (environmental and socio-economic) on downstream receptors. We adopt a participatory ‘weight-of-evidence’ approach to effectively guide, target and facilitate the delivery of adaptive catchment management for an array of intended ecosystem services-based outcomes.
To ensure that catchment management interventions are timely, targeted, necessary and to maximise the ecosystem services benefits realised, we use the latest modelling, surveying and mapping techniques to investigate landscape condition, identify threats to ecosystem health (e.g. sources of water pollution), create integrated catchment management plans and target additional monitoring. These comprehensive reviews of pre-existing and novel primary data are supplemented with additional, locally derived data and refined using expert judgment and stakeholder insights. This integrated approach, marrying an exhaustive review of data and evidence with our significant expertise of on-the-ground delivery, allows us to deliver significantly greater and more diverse social, environmental and economic outcomes.
Recently, the WRT toolbox of measures has been extended to incorporate an array of Nature-Based Solutions (or ecosystem-based adaptation measures). In addition to water quality protection measures, it now also includes a comprehensive suite of interventions for: 1) soil & water management; 2) the creation and management of woodland, and 3) both Natural Flood Management (NFM – also known as Working with Natural Processes) and water resource resilience (drought alleviation) measures.
WRT have also developed a ‘toolkit’ for the delivery of collaborative local-governance, participatory strategic environmental planning (including ecosystem services and natural capital) and nature-based solutions co-creation. The WRT Co-Creation Toolkit is an evidence-based, social-capital-creation approach that integrates the theories of design research, action research and participatory design into a highly effective approach that can deliver robust and replicable knowledge-, social- and natural-capital outcomes in an array of contexts. This Toolkit has been tested in diverse landscapes (urban, rural, both), at various spatial scales and with diverse stakeholder groups. Our aim is to build social and knowledge capital among local stakeholders, develop a clear mandate for action and integrate the strands of the programme together.
About Dr Nick Paling
Dr Nick Paling, Head of Evidence & Engagement at WRT, specialises in the analysis, visualisation and communication of strategic information to engage stakeholders and ensure that environmental actions are co-designed, targeted and co-created in locations that give the greatest magnitude and diversity of social, cultural, economic and environmental outcomes.
For ~15 years, Nick has been working as a ‘knowledge-broker’ and co-creation-facilitator on a wide array of local collaborative governance, participatory environmental planning, community-based climate resilience/adaptation and NBS co-creation projects (in both urban and rural landscapes).
Nick works with stakeholders to build a shared vision of a resilient future landscape based on robust spatial evidence and information via a fully participatory process. He works with citizens, stakeholders, technical specialists and policy-makers to support their learning and build consensus about the challenges faced, before collectively working to target, design and deliver (co-create) the most effective NBS for building community resilience.
Since 2017, Nick has been working as a European Commission (Horizon 2020 and Joint Research Centre) Technical Expert in the fields of water-sensitive urban design, urban NBS, strategic evidence (including ecosystem services and natural capital) and collaborative/co-creation approaches to the creation of NBS (including the Living labs approach).

Integrated Management of Groundwater-Surface water under influence of climate change
This study presents the development of an integrated surface and subsurface model for transient analysis of groundwater flow, salinity intrusion, river flow and river inundation, to aid decision-making and management of water resources. A coupled framework, linking subsurface flow and surface hydrodynamics, was developed and applied to a real-world case study of Pingtung coastal aquifer in southwest of Taiwan. FEFLOW was adopted to develop a three-dimensional variable-density finite element model to study the combined effects of over-abstraction and seawater intrusion. The developed groundwater model was coupled with river network model using MIKE 11. The developed model was calibrated and validated based on observed data. The model was used to analyse the interaction between the surface water and groundwater and the effects on seawater intrusion. Also, the relationship between rainfall, surface water and groundwater recharge lag time was studied.
About Mahdieh Dibaj
I recently defended my PhD in Integrated management of Surface water-Groundwater under influence of climate change, seawater intrusion, over abstraction, and flooding. The project was partially funded by the Royal Society and the National Taiwan University (NTU) and the results were presented in several national/international conferences and published in high ranked journals, with two more papers under review. I also have experiences in working as a graduate research assistant in an international project supported by the British Council.

Knowledge co-creation for climate adaptation and water justice: a transdisciplinary approach to the SenseMaker toolkit
This talk explores a method for joint knowledge production to serve climate adaptation in the context of both urgent and chronic stressors. In a water governance research project in Cape Town, community activists and researchers collaborated to design a study that could amplify the voices of residents in low-income and informal settlements around water service issues. The project helped to understand the mismatch between government interventions and people’s lived realities, and also generated new skills and knowledge to empower the community activists in their efforts to address water injustice in the city. The research also generated important insights about the role of knowledge in shifting from incremental to transformative adaptation, that can simultaneously address environmental and social emergencies.
The talk is based on two recent publications:
About Johan Enqvist
Enqvist’s research explores people’s relationship to the rest of nature, focusing on values, perceptions and actions to protect, conserve and restore ecosystems and natural resources. He is currently funded by VR (the Swedish Research Council) to investigate how the recent drought in Cape Town, South Africa, affected people’s awareness of and behaviour in response to water scarcity. Justice and inequality are important aspects of this work, and Enqvist collaborates directly with various community-based groups and local and international NGOs involved with social as well as environmental issues.

Adapting to Climate change – from flood defence to flood resilience
The world is becoming increasingly urbanised with more of the population living and working in urban areas. Increasing urbanisation and economic growth can provide significant community benefits but also present a range of challenges. Floods account for about 50% of all fatalities from natural hazards, with an about £25 billion in damages per annum. The impact of climate change on sea level rise, storminess and rainfall is set to increase significantly. Society is therefore faced with the challenge of finding solutions to complex and interrelated problems to enable creation of thriving, liveable and safe places that are resilient to the extremes of water and adapted to climate risks.
The presentation will show why flood risk solutions need to be multifunctional and much wider to reduce the probability and consequences of flood risk now and in the future. It will illustrate these with global examples of good practices

Benchmarking household water access and use globally: a new tool and many new questions.
Problems with water quality and quantity are increasing in frequency and severity throughout the world. High-resolution, globally comparable data that go beyond availability to assess access and use have been extremely helpful for understanding the human health impact of other health issues, e.g. food insecurity, but have not existed for water. To fill this gap, Prof Young has led the development of the Household Water Insecurity Experiences (HWISE) scale, the first cross-culturally equivalent way of measuring water access and use (hwise.org). The HWISE Scale can be used to estimate prevalence of household water insecurity and to investigate its causes and consequences. The HWISE Scale is currently being implemented globally, including by the Gallup World Poll, to benchmark water access and use, as well as by Cardiff University in efforts to assess urban water security in East Africa. We will conclude with discussion of new opportunities to use and analyze household water security data.
Increasing water security challenges pose risks to achieving sustainable development. However, there is a wide range of different approaches for measuring water security. For example, it can be quantified through a physical aspect, highlighting the impact of water resources, availability, supply and hazards; it can also be assessed from a human angle, focusing on the water impact on the experiences of households and individuals. In this study, we aim to explore the potential in applying a multifaceted understanding of water security, connect physical water processes with human water experiences using metrics such as the HWISE Scale, and discuss new opportunities in using and analysing household water security data.

What can social sciences tell us about digital water transformations?
Digital water transformation is often written about as though universally desirable, inevitable and capable of addressing the complex socioecological challenges. However, we should not take digital water innovation for granted; there are tensions and unintended consequences of digital transformation, its social and political dimensions are often neglected. This talk introduces case studies of digital water development, bringing examples of technological innovation into dialogue with literature and empirical research from across the social sciences. From sensing technologies, platform economies to cyber security regulations, digital technologies are reconfiguring how we relate to water system.
The presentation will conclude with an outline for a novel, pluralistic and interdisciplinary research on digital water development.
About Dr Ola Michalec

What does the cosmos tell you about soil hydrology?
The water stored in soils represents a small compartment of the whole hydrological cycle. Yet, it is one of the key factors controlling hydrometeorological processes at the land surface. For example, soil moisture controls the partitioning of rainfall into evapotranspiration, runoff or infiltration, and relates to our ability in monitoring and predicting floods and droughts. Typically, soil moisture can be estimated with two very different approaches: either with localized point-scale (few centimeters) measurements or with satellite remote sensing products covering a much larger area (many kilometers). With the recent effort to move towards hyper-resolution global land surface and hydrological aimed at (sub)kilometer scale, this presents a challenge as neither methodology estimates soil moisture at the scale of interest. However, in the last decade, the development of cosmic-ray neutron sensing technology has allowed for soil moisture to be accurately estimated at unprecedented sub-kilometer scales, on the order of hundreds of meters with a single sensor. Since the early 2010s, this technology has evolved and been continuously applied globally with potentially hundreds of cosmic-ray neutron sensors located across a wide range of biomes. This seminar is aimed at introducing this technology to a wider audience, showing examples of applications in the field and in combination with numerical models, as well as highlighting potential challenges and opportunities ahead.
About Dr Rafael Rosolem
Dr Rafael Rosolem graduated with a BSc in Meteorology and MSc in Agricultural Systems Ecology, both at the University of Sao Paulo in Brazil. He received a PhD degree from the Department of Hydrology and Water Resources at the University of Arizona before joining the Civil Engineering Department at the University of Bristol in 2013. Dr Rosolem’s work focuses on improving the representation of hydrological processes in land surface and hydrological models using experimental data from different regions of the world, particularly from developing countries where data access is limited. He has extensively worked in the Amazon region in Brazil, using flux towers to better inform numerical models, and he has taken part of the pioneer COSMOS project which established the first national network of novel cosmic-ray neutron sensors across continental USA. More recently, Dr Rosolem’s research has also focused on the African continent and in the UK.

Drought in the Greater Horn of Africa: past, present and future
Much of the Greater Horn of Africa (GHA) is semi-arid, despite its tropical location. Droughts are part of natural climate variability, and diverse evidence from paleoclimate and anthropology points to the periodic occurrence of megadroughts leading to famine and the fall of kingdoms. More recently drought has increased in frequency, exacerbating food insecurity for many in the region. Warming of the Pacific has been implicated in this trend, though the extent to which this can attributed to anthropogenic influence is debated. However, standing in direct contrast to this drying trend are the 21st century projections from climate models which consistently project increasing rainfall.
In this talk I will review the history and future of drought in GHA. I will discuss the latest understanding of the drivers of recent and future trends, and present latest efforts by research and humanitarian organizations to build societal resilience to droughts and their associated impacts.
About Dr David MacLeod
My research expertise includes climate science and predictability from days to decades, the use uncertain information for humanitarian decision-making and data visualisation. In September 2020 he joined the University of Bristol, contributing to the H2020 project DOWN2EARTH: making climate information relevant for water security. My most recent previous work involved the development of early warning systems for flooding and drought in Kenya and the Greater Horn of Africa, alongside partners in the Kenya Red Cross, Kenya Meteorological Department and the National Flood and Drought Monitoring Authority.

Managing the Water we Eat
This presentation discusses the central role of water management for the environment and particularly for sustainable food systems. Increasing water scarcity, due to climate change and other environmental and societal changes, calls for a transformational shift in the way we manage water. However, this is challenging as water management is characterized by overlapping decision spaces and scales and inter-dependencies amongst various water users, of which agriculture is usually the largest and responsible for more than 80% of water withdrawals in agrarian economies. Understanding the spatio-temporal variability of water resources as well as the domains of different water users, key actors and their objectives, and drivers and barriers for transformational change in water management is required. A scale-specific approach in which agricultural water use is embedded in a larger systems approach (including natural and human systems) is suggested. This is the basis for policy coherence and designing of effective incentive schemes to change agricultural water use behavior

Ganat and Geo-electrical prospecting for detection
In most of Iran’s areas, especially dry areas, there are no lakes or rivers on the surface. So, in the past, the water of cities and towns had been supplied by underground water channel systems that are called Qanat. Most of these old channels were abounded and collapsed. Following collapsing of the qanat walls, an essential matter is the detection of these human-made structures to prevent them from possible destruction to surrounding buildings and lifelines. In this webinar, I’m going to briefly speak about the importance, technical features, and the excavation of ganats. Detection of qanats is one of the main geotechnical concerns in the development of cities in most parts of Iran. So, I deal with a geophysical survey carried out in a critical urban area of Kerman, southern Iran. This webinar presents the results of a near-surface survey carried out by the Electrical Resistivity (ER) method.

Technology vs information to promote conservation: Evidence from water audits
We study the impact of audits on water conservation, distinguishing between the information and technological components. We observe water consumption for up to 18 months for 10,000 households in the South East of England who received the visit of a so-called Green Doctor. We find that water-saving devices decrease water consumption by 2-4%, with an effect that is persistent over 18 months. Devices reducing water pressure are particularly effective, while shower timers are ineffective. The information component of the water audit has a large initial impact, but this gradually fades to a drop in consumption of 2% after 12 months. Technology appears to be more cost-effective than information provision and this can help in the design of policy interventions.

Transforming urban water resilience: the role of household self-supply in sub-Saharan Africa
Water shocks and water stress stretch the ability of governmental authorities to respond, leading individuals to take action for themselves. Individual actions can be a positive element in building collective resilience but may equally undermine collective provision or lead to inequitable outcomes. Across sub-Saharan Africa, urban households are turning to personally-procured non-piped water supplies to ensure the security of their water supplies. In this presentation I explore these trends and suggest that a stronger understanding of household motivations is required in our consideration of urban water security and the longer-term implications of this for the resilience of urban water supplies.

Stable isotopes are not enough – Using tree hydraulics to understand tree water use
The stable isotopes of hydrogen and oxygen (δ2H and δ18O, respectively) have been widely used to investigate tree water source partitioning. These tracers have shed new light on patterns of tree water use in time and space. However, there are several limiting factors to this methodology (e.g. the difficult assessment of isotope fractionation in trees, and the labor-intensity associated with the collection of significant sample sizes) and the use of isotopes alone has not been enough to provide a mechanistic understanding of source water partitioning. In this talk, I will discuss how measurements of tree water deficit can be used to identify shifts in source water uptake by trees. Our research shows that tree water use is a dynamic process on the time scale of days. I will also discuss how this method could improve our understanding about forest water use at larger scales.

Event Management and Event Response Planning for Smart Water Networks
The water industry in the UK and worldwide has a pressing need to better manage interruptions to water supply caused by various failure events, such as pipe bursts, equipment failures or water treatment work shutdowns. One way of doing this is by making use of the increasingly available real-time sensor data collected in water distribution systems, as well as by using hydraulic models in real-time. Currently, real-time sensor data and real-time hydraulic modelling are not used much in a water utility’s control room, especially when it comes to identifying a suitable strategy to respond to failure events in near real-time.
This presentation provides an overview of a new response methodology to support decisions made by control room operators when dealing with various failure events in a water distribution system. This methodology was developed and validated in the context of a PhD project, in University of Exeter. An integral part of this work was to develop an interactive decision-support tool, which guides/supports operators in identifying an effective response solution in near real-time (i.e. usually required up to 1 hour after the event detection/localisation).
The proposed response methodology considers: (i) structured yet flexible approach supporting and guiding the operator throughout the entire response process to water network failure events, whilst allowing the operator to have a final say; (ii) novel interaction with the operator in near real-time via the proposed tool (e.g. allowing operators to propose different ‘what-if’ scenarios without being hydraulic experts); (iii) provision of automatically generated advices (e.g. near optimal response solutions via a novel heuristic algorithm and assessed end-impacts); and (iv) improved impact assessment. An integral part of the new response methodology is the development of a new method to identify near optimal response to failures in water distribution networks.
The new response methodology was tested, validated and demonstrated on a semi-real case study. The implementation of the new response methodology via the tool enabled operators to identify a response solution better (i.e. with lower end-impact and cost) than the solution based on the current response practice of utilities. The results obtained from this case study, demonstrate that the new response methodology works well and that it has a potential to improve water utilities’ current practice. The new heuristic optimisation method was validated and demonstrated on two semi-real case studies. Based on the results obtained it can be concluded that the new heuristic-based method works well (i.e. it is reliable and robust) and is able to identify near optimal response solutions in a computationally fast manner (i.e. in near real-time). This, in turn, enables this method to be used in near real-time in real-life situations.

Estimating the size distribution of plastics ingested by animals
The ingestion of plastics appears to be widespread throughout the animal kingdom with risks to individuals, ecosystems and human health. Despite growing information on the location, abundance and size distribution of plastics in the environment, it cannot be assumed that any given animal will ingest all sizes of plastic encountered. Here, we use published data to develop an allometric relationship between plastic consumption and animal size to estimate the size distribution of plastics feasibly ingested by animals. Based on more than 2000 gut content analyses from animals ranging over three orders of magnitude in size (lengths 9 mm to 10 m), body length alone accounts for 42% of the variance in the length of plastic an animal may ingest and indicates a size ratio of roughly 20:1 between animal body length and the largest plastic the animal may ingest. We expect this work to improve global assessments of plastic pollution risk.

Insights into blue spaces and human wellbeing: Findings from the BlueHealth International Survey
While there are many health risks, there is growing evidence that blue spaces (that is, natural environments prominently featuring water such as coasts, lakes, and rivers) can promote good human health and wellbeing. However, this literature is often disparate, featuring a range of different health outcome measures, metrics of blue space “exposure”, and is limited to studies conducted in individual countries like the UK and the Netherlands whose populations have very specific relationships with their e.g. coastline and canals, respectively. As part of the Horizon 2020 BlueHealth project, we conducted a standardised 18-country online survey to address many of these drawbacks. This seminar will guide you through a whistle-stop tour of findings from this survey so far and concern both ‘blue’ and ‘green’ spaces. Example results will look at how much time in nature in optimal for mental health gains, how people with common mental health disorders experience natural environments, whether blue and green spaces are associated with reduced inequalities in health, and whether there are associations between exposures to blue and green spaces and addictive behaviours like smoking or alcoholism.

Antimicrobial resistance in water systems
Antimicrobial resistance (AMR) is one of the greatest threats facing modern society. Natural environments are increasingly recognised as playing an important role in AMR, but also a comparatively understudied potential mechanism to mitigate it. How antibiotics and other compounds that may increase AMR enter the aquatic environment will be outlined, followed by a discussion of the current environmental risk assessment of antibiotics landscape from an AMR standpoint. Current and possible future research avenues will be introduced.

Water-Food-Energy Nexus in Transboundary River Systems: A case study of the Nile basin
The Nile River basin is a transboundary river basin in East Africa shared by 11 countries and home for about 250 million people. The basin is currently experiencing rapid population and economic growth. Consequently, the Nile countries have devised ambitious master plans to tap the Nile resources potential to meet the growing water, food and energy demands of their populations and sustain their expanding economies. The – near completion – Grand Ethiopian Renaissance Dam (GERD) is the largest development in the basin and has the potential to deliver regional economic benefits and improve regional cooperation. However, it also has raised regional tensions – between Egypt, Ethiopia and Sudan – which have gained international attention and could hinder the livelihoods in downstream countries. Yet, there is no unified agreement on filling and operation of the reservoir. The Nile is also vulnerable to climate change that is likely to add further uncertainties to the hydrologic river regime. To this end, the talk will highlight the opportunities, challenges in the Nile region as well as the modelling methodology and key results from my PhD research at the Centre for Water Systems.

COVID-19 and the Water Sector: Understanding impact, preparedness and resilience through a sector-wide survey
The COVID-19 pandemic involved unprecedented measures, drastically altering the way we live and work. To understand the impact of the pandemic on the water sector, a questionnaire was co-designed by the Chartered Institution of Water and Environmental Management, a research team and a panel of industry experts. Almost 80% of water sector employees were able to continue their usual role, suggesting high levels of resilience, borne out of good incident management procedures. However, more than a third reported changes in customer behaviour, such as impacts on the supply chain and capital programmes, and changes to water demand patterns.
In this presentation, I will outline technical challenges identified in the survey – including a delayed daily peak demand, and weekday consumption habits matching traditional weekend patterns – and discuss longer term opportunities and challenges associated with these changes. Furthermore, responses to the survey implied a potential cost burden could arise for water companies, due to increased treatment costs, from a changing wastewater load; decreased revenue, with water consumption shifting from metered to unmetered buildings; and the financial implications on customers, affecting their ability to pay their bills.

Configuration of micro-scale modelling for disaster evacuation simulations
Following a Tsunami warning alert the population of residents lying within high risk regions have limited time reach safe distance. Depending upon their individual responses some residents will seek to evacuate via foot and some via vehicles, however the latter could be problematic due to the volume of traffic looking to simultaneously evacuate a region resulting in gridlock scenarios and potentially endangering more lives.
This research looks to examine the evacuation of residents within a city known to be of potential risk to Tsunami events and develop a micro-scale model simulating the movements of residents either by foot, by car or a combination of them both.
This presentation highlights some of the early work being undertaken in the development of a micro-scale model and the challenges and applied solutions used to overcome some of the limitations relating data availability.
