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.

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.

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.
About Lewis Elliott
Lewis is a lecturer in environment and public health at the European Centre for Environment and Human Health, University of Exeter Medical School.

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 rector-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.
