📥  Other, Water Resources

This May sees the next talk in the monthly 'Water Colloquium' series organised by WIRC @ Bath exploring the breadth of water research being undertaken at the University of Bath and beyond.

Title: Linking chemical-soil interactions to pollutant fate and transport from soil to water

Speaker: Dr Brian J. Reid, Reader, School of Environmental Sciences, University of East Anglia

When: Thursday 18th May 2017 at 1.15pm

Where: Room 2.1, 6 East, University of Bath (Location and maps)

Abstract: The seminar will begin by introducing the fundamentals of how chemical and physical phenomena underpin soil-pollutants interactions. From this perspective the implications of these interactions for pollutant bioavailability and transport will be developed. I will introduce seminal research relating to the application of cyclodextrins as bioavailability mimetics (and standardisation with the ISO). I will provide insights into the interplay between pollutant exposure, pollutant bioavailability and microbial adaptation. These dynamics govern the opportunities for pollutants to move through the environment and to be degraded. To conclude this half of the seminar, I will outline ongoing research with: a European agrochemical company and a UK water company, with whom, we are developing innovations to mitigate pesticide release into the environment and to evaluate pesticide attenuation-competence across water catchments. The second half of the seminar will consider the opportunities to use carbonaceous materials to alter the bioavailability and fate of chemicals. Here I will introduce experiments that highlight the influence of biochar on: soil properties and soil hydrology, and; the efflux of soil colloids, dissolved organic matter and agrochemicals. I will highlight recent successes in the application of biochars to mitigate pollutant phyto-accumulation and markedly reduce the cancer risks in China’s Cancer Villages.

Title: A medium term 'crisis' in water? Might Brexit be the answer?

Speaker: Dr Martin HurstMartin Hurst photo

When: Thursday 4th May 2017 at 1.15pm

Where: Room 3.6, Chancellors' Building, University of Bath (Location and maps)

Abstract: The water industry has enjoyed 15 years of static prices, while profits have been maintained and by and large improvements in service have continued.

But this may be coming to an end. A recent peer reviewed study by Atkins and others for Water UK showed that the likelihood of future droughts was markedly greater than had previously thought. There has been systematically underinvestment in asset maintenance. Catchments are under increasing ecological pressure. Population growth, new development and climate change are ever present. And the financial backdrop to the last 15 years’ price falls is coming to an end.

If this combination of factors is not to lead to a perfect storm of rising bills, falling service and increasing ecological damage we need a paradigm shift. Whatever the pros and cons of Brexit more widely, an ability to think afresh about environmental legislation – moving from process to outcome based regulation - coupled with the need to rethink agricultural support may provide an important opportunity for water.

The resultant new approach to catchment management could involve a genuine partnership between land managers, water companies and flood defence agencies with benefits for water availability, environmental quality and flood defences. All with potentially reduced water bills.

There seem to be two ways of achieving this: evolutionary change, or a move to a ‘system operator/natural capital trading’ approach. Neither are without their risks. Both require a degree of cross sectoral and multiple benefits thinking which has not proved easy to achieve in the UK to date.

Speaker: Dr Lee Bryant

When: 16 March2017 at 1.15pm

Where:  CB 4.8,University of Bath (Location and maps)

Abstract: Oxygen and mixing conditions in aquatic systems have a significant influence on the biogeochemical cycling of nutrients, metals, and other species at the sediment-water interface; these fluxes often control water quality in lakes and reservoirs. In an effort to counter problems with decreased water quality stemming from anoxic conditions, engineered techniques such as hypolimnetic oxygenation systems are being used more and more prevalently to increase aquatic oxygen concentrations and reduce concentrations of deleterious soluble species. Decreased oxygen levels in oceans are also becoming increasingly problematic due to enhanced anthropogenic effects and global warming. In both freshwater and marine systems, fluxes of oxygen, nutrients, and other chemical species are known to be strongly controlled not only by concentration but also by turbulence such as internal waves; however, hydrodynamics can be highly variable and effects on biogeochemical cycling and corresponding water quality are not currently understood. Based on in-situ microprofiler and aquatic eddy correlation measurements, results will be presented from three process studies focusing on (1) the effects of internal waves (e.g., seiches), (2) bioturbation, and (3) engineered hypolimnetic oxygenation / aeration on sediment-water fluxes of oxygen and manganese in lakes and reservoirs. These studies will be used to highlight the physical and chemical processes controlling biogeochemical cycling and related water quality in aquatic systems.

Development and application of a novel PIC method to Fluid-structure interactions

Qiang ChenQiang Chen

PhD Research Programme in Civil Engineering, University of Bath

Abstract
With increasing computing power, Computational Fluid Dynamics (CFD) modelling has been considerably developed in many research areas. This work is motivated by developing a hybrid method for numerical modelling of fluid-structure interaction in the coastal and offshore engineering environment. In particular, this is based on the Particle-In-Cell (PIC) method where both particles and grid are utilised. While the particles are used for tracking free surfaces and solving the nonlinear advection term of the Navier-Stokers equations in a Lagrangian manner, the underlying grid is employed for solving the rest non-advection parts in an Eulerian sense. The idea being that the method should have both the flexibility and efficiency from pure Lagrangian methods (based on particles) and Eulerian methods (based on grid), respectively, with a reasonable accuracy.

Biography
Qiang obtained his Master Degree at Dalian University of Technology, China. He is now a PhD student of Dr Jun Zang at the WEIR research unit.

 

Assessment and mitigation of storm runoff loads from an informal settlement (slum)

Olivia CookeOlivia Cooke

PhD Research Programme in Civil Engineering, University of Bath

Abstract
One of the biggest global health problems today is that posed by urban conditions, most significantly in informal settlements. Within informal settlements, the lack of infrastructure including sanitation and sewage facilities can generate serious problems for health and the environment. Stormwater runoff influences these issues and it is necessary to understand the processes and characteristics of runoff to mitigate health risks from it. The aim of this PhD is to develop a scientific theory which determines how stormwater runoff, quality and quantity, is influenced by human and environmental factors, focussing on the case study of the informal settlement Enkanini, located in South Africa.

Abstract
In Martin’s colloquium, he will reflect on the development of modern water systems in and around buildings and how they fit in the wider urban context. He will make the argument we need to consider water in a more integrated manner and how we might look to nature for inspiration.

Water plays an essential part in the life of our cities. It is required to provide our basic needs for drinking water and sanitation, for industry and commerce and plays an important part in our health and well-being. Water is both an enabler for allowing cities to work and can also present a risk in the form of flooding and drought. We are facing problems caused by both too little and too much water. As well as climate change, this is being exacerbated by population growth and urbanization. In addition, for many cities, existing urban water infrastructure is often at or approaching its maximum capacity.

In the ancient world, large cities begun to develop aqueducts and river-based sewerage systems to support their development. Growing understanding of waterborne diseases and the introduction of the water flushed closet led to the provision of a centralised water supply and wastewater treatment models which have served us well for over 100 years. As many of these ageing systems are now reaching capacity, new models for water systems are presenting themselves. There is a growing understanding of the need to deliver smarter, better, cheaper, more resilient and environmentally sensitive water and wastewater systems.

The increasing demand placed on our water infrastructure has meant traditional centralized infrastructure may not be adequate to satisfy our urban needs in an economic manner. Decentralization of water infrastructure has grown extensively as a viable solution including non-potable water from sources such as greywater, rainwater and stormwater harvesting where policies are trending towards a more rational use with integrated systems.

In our congested cities, access to blue and green spaces, as well as contributing to the management and control of water, can provide multiple health benefits. These range from reduced exposure to pollution and high urban temperatures through to improved mental well-being and providing opportunities for recreational use and wildlife habitats. Integrating these spaces with transport routes provide safe and appealing cycling, walking and running routes to allow citizens to travel more simply.

Water for buildings

When considering water demand for cities, much of it is related to buildings. Adequate water supply and drainage systems are a necessity for the safeguarding of the health and hygiene of building users; if they fail there can be serious health and safety consequences.

The design of our water systems are rightly influenced by regulations, codes and standards. But regulations, codes and standards do not always keep pace with how water needs to be managed, the influence of changing demands and needs of citizens as well as climate change. We need up-to-date data and decision support tools.

The need for robust data to drive engineering

Much of the design data underpinning these codes was collated in the 1970s. However, water appliances and patterns of use have changed dramatically since then. New water appliances have appeared and others have become more efficient. If the codes are followed, it is likely that hot and cold water systems will be oversized (and therefore not as economical) which can also lead to other costs such as increased space take, increased energy and water use as well as lower throughput of water and the water quality issues that brings.

Resource efficient building designs often incorporate water re-use systems such as rainwater harvesting, greywater and blackwater reuse, alongside standard drinking water provision. Hot and cold water distribution systems need to be designed to operate safely and hygienically with a range of demands placed upon them. Hot water temperature needs to be regulated to control bacterial growth whilst avoiding potential scalding.

Once buildings and their water systems are considered holistically with the infrastructure that serve them, we are able to apply new thinking to find ways to enhance their overall resilience. Good modelling and robust data is required to provide evidence base to drive new solutions.

Looking forward: towards a circular economy for water

Nature provides us many clues as to how we should manage water in an integrated way. We are all familiar with the basic premise of the water cycle. However, much of our water man-made water systems are linear in nature: running from catchment basin through to use through to discharge and eventually to the sea. For many contexts, a linear model does not allow for optimisation. For example, a circular approach can allow for value to be extracted from a wastewater stream so that resource flows can be enhanced.

Depending on the scale, perhaps a better approach is to circulate water in closed loops. In this model, water can reused, better maintaining its value. Closed loop systems can operate at the ‘unit’ (for example, process or building) scale, at development (or campus) scale or at the bigger ‘city’ scale.

Taking a systems approach, we are beginning to better understand the role that water plays in the ‘circular economy’.

When: Thursday 15 December 2016 at 1.15pm

Where: Room 3.6, Chancellors' Building, University of Bath

Abstract: The occurrence of record-breaking flood events continuous to cause damage and disruption despite significant investments in flood defences, suggesting that these events are in some sense surprising.  This study develops a new statistical test to help assess if a flood event can be considered surprising or not.  The test statistic is derived from annual maximum series (AMS) of extreme events, and Monte Carlo simulations were used to derive critical values for a range of significance levels based on a Generalized Logistic distribution.  The method is tested on a national dataset of past events from the United Kingdom, and is found to correctly identify recent large event that have been identified elsewhere as causing a significant change in UK flood management policy.  No temporal trend in the frequency or magnitude of surprising events was identified, and no link could be established between the occurrences of surprising events and large-scale drivers.

Time: 5.30pm, Thursday 23rd November 2016

Venue: Room 4.1, Chancellor's Building, University of Bath (Location and maps)

Abstract:

Join the Institute of Water South West Area as we investigate Shale Oil and Gas Exploration with RSKW Ltd.

RSKW has advised water and energy companies internationally on issues relating to shale oil and gas extraction - from geological, groundwater and general environmental perspectives, as well as delivering guidance on strategic risk management. RSKW are part of a European and US consortium currently mid-way through the delivery of a €2.7 million project, researching the environmental aspects of Shale Gas operations. The project - known as SHEER (SHale gas Exploration and Exploitation induced Risks) is funded through the HORIZON 2020 programme. The project outputs will inform the legislation for and regulation of Unconventional Oil and Gas across the whole of Europe.

Water management and shale oil and gas - Andrew Gunning of RSKW Ltd will address the truths, myths and legends surrounding exploration for shale oil and gas. Initially developed in the US, this was an emergent phenomenon which resulted in a rapid increase in onshore drilling using the evolving techniques of horizontal drilling and ‘fracking’. This presentation draws on experience gained from project work for UK water companies and the EU SHEER project, in assessing risks to drinking water aquifers, the regulations in place to mitigate those risks and areas where further investigation is required.

Kindly hosted by the University of Bath, this event will also provide an opportunity to hear about WIRC @ Bath and the WISE CDT.
