CONNECTED WATERS RESEARCH ANNUAL REPORT 2014 <5>

The Connected Waters Initi-ative Research Centre (CWI) is UNSW’s Groundwater Research Centre. The CWI is a cross-faculty research group, with staff based in the Schools of Civil and Environmental Engineering; Biological, Earth and Envi-ronmental Sciences; Mining Engineering; the Mark Wain-wright Analytical Centre, and UNSW Law. As a cross-fac-ulty centre, the CWI rotates between presiding faculties.

During 2014 the Centre presided in the Science Faculty.

2014 saw the end of an era with the conclusion of funding in June from the ARC / National Water Commission co-funded centre for excellence, the National Centre for Groundwater Research and Training (NCGRT). In 2014 we remained at full staffing capacity, and we focused on the submission of re-search papers and delivering conference presentations on our NCGRT funded research. PhD researchers which have been part-funded by the NCGRT will continue to graduate over the next two-years.

Funding for the national groundwater infrastructure program was continued throughout 2014. It is funded from the Federal Government NCRIS program, and is managed by the CWI. These long term monitoring sites in four states monitor a range of environmental parameters relevant to groundwater, including river and groundwater levels and automatic weather stations, as well as a range of state-of-art analytical facilities, mostly hosted at UNSW. Within NSW, research infrastructure is concentrated at the UNSW Wellington and Fowlers Gap Field Stations and in the Namoi Valley.

As 2014 came to an end, the CWI team were focussing on increasing the portfolio of Category 1 and 2 funding. Dr Martin Andersen secured a $700,000 grant as part of a consortium to inform the Office of Water Science on ecohydrological respons-es to coal seam gas extraction and coal mining. Andy Baker, Wendy Timms and colleagues commissioned a new ARC LIEF funded isotope mass spectrometry facility.

CWI members continue to be engaged with the development of government guidelines and policy. In 2014 Associate Prof. Bryce Kelly contributed to the reports on specific CSG related issues for the NSW Office of the Chief Scientist & Engineer.

In 2014 our research was well represented at the International Association of Hydrogeologists (IAH) Annual Congress in Mar-rakech. The CWI team was also well represented at the world’s largest geoscience conference, the American Geophysical Union (AGU) Fall Meeting in San Francisco. The CWI team was also present at the Goldsmith conference in Sacramento (US). At the EGU conference in Vienna (Austria) Dr Gabriel Rau and Dr Mark Cuthbert presented talks and convened a session on surface water groundwater interactions. CWI staff also partic-ipated in the 4th International Conference on Water Manage-ment in Mining in Chile and finally at home in Australia at the Australian Earth Science Convention (AESC) in Newcastle.

In 2014 Dr Cameron Holley received the prestigious Interna-tional Union for Conservation of Nature (IUCN) Academy of Environmental Law Junior Scholarship Award for his contribu-tion to environmental law scholarship.

CWI promoted several media releases in 2014. Some of these including: Dr Mark Cuthbert promoting his latest paper on how early human evolution may have been dependent on ground-water resources in Uniken; an ABC story on the CWI experi-mentation at Wellington Caves to measure surface-groundwater connectivity by tracking movement of applied water between the ground surface and the caves; and finally the promotion of a study by Dr Mark Cuthbert and co-workers, also at Wellington Caves, on the process of in-cave evaporative cooling and how this may affect the interpretations of past climate reconstruc-tions from stalagmites.

In 2014 the CWI said farewell to postdoctoral researchers Steve Bouzalakos, Hoori Ajami, Alessandro Comunian and Sanjeev Jha. These include new post graduate and research associate staff Katie Coleborn, Eliza Wells, Calvin Li and Scott Cook joined the team, and new affiliate staff includes Stephan Eberhard, Dar-ren Sinclair, Mark Cuthbert and Catherine Jex. Dr Gabriel Rau became faculty, with a fixed-term position in the School of Civil and Environmental Engineering. In 2015 we look forward to the arrival of ARC Future Fellow Denis O’Carroll, who will undertake research into nanoparticle transport and fate in groundwater, based in Civil and Environmental Engineering.

Our research in 2014 focused on finalising research under the National Centre for Groundwater Research and Training and a portfolio of new research grants.

National Centre for Groundwater Research & Training

Within the Australian Research Council and National Water Commission co-funded Centre for Excellence for Groundwater Research and Training (NCGRT), we maintained full staffing capacity throughout to the end of ARC/NWC funding for the centre on the 30th of June 2014. The NCGRT provided approx-imately $6.9M funding for the training of Honours, PhD and post-doctoral researchers from 2009 to 2014. CWI has pro-duced a large volume of research and outreach outputs and achieved all its key performance indicators during its lifespan. The UNSW-NCGRT team, all based in the CWI, published many high quality papers in international peer-reviewed journals in 2014 from research funded in the NCGRT (see publication list below) and in fact publications based on work in the Centre is still expected to be published in 2015 and beyond.

In addition to the published papers, numerous presentations of research findings were given at the International Association of Hydrogeologists Congress in Marrakech, Morocco, the Ameri-can Geophysical Union Fall Meeting in San Francisco, the Gold-schmidt conference in Sacramento (US), the Australian Earth Science Convention (AESC) in Newcastle and other internation-al conferences.

NCRISThe federal National Collaborative Infrastructure Scheme (NCRIS)

The Connected Waters Initiative Research Centre manages the National Collaborative Infrastructure Scheme (NCRIS) Ground-water Infrastructure program, supported by partners at Flinders University, Monash University and the Australia National University. NCRIS provides sustainable and effectively targeted investment in world-class national-scale research infrastructure. It is Australia’s leading edge research infrastructure network which provides the equipment and expertise to enable Aus-tralian researchers to do world class research, and Australia’s industries to increase their productivity through new products and processes. Further details about NCRIS can be found at: https://education.gov.au/national-collaborative-research-infra-structure-strategy-ncris

By 2014 the NCRIS Groundwater Infrastructure sites were all installed, instrumented and fully operational and live data was

streaming back to the NCRIS data website (http://groundwater.anu.edu.au/) from the telemetered sites. Only minor repair and development work was still taking place at a few sites.

In May 2014 the NCRIS Groundwater Infrastructure project at the Fowlers Gap Arid Zone Research Station near Broken Hill was officially launched. UNSW holds a lease in perpetuity on the property and it is an important site for teaching as well as research. Daily rainfall on the property has been continuously monitored for more than 30 years, providing a unique, long-term record of high density rainfall monitoring in a dry region. Now, the Fowlers Gap site is monitored using the Telstra 3G network. The 18 manual gauges have been replaced with tip-ping-bucket gauges linked to a data transmission network that makes it possible to view the daily data from the farm office or remotely via the web. Besides the rain gauges the monitoring

project, which was developed by CWI Professor Ian Acworth, the Gary Johnston Professor of Water Management, also involves a network of observation bores, climate stations and surface water weirs. Fowlers Gap is the only research station in the arid zone of NSW. University staff in attendance at the opening included Emeritus Professor Terry Dawson, UNSW (kangaroos); Professor Ian Acworth, UNSW (water); Professor Andy Baker, UNSW (water); Associate Professor Simon Griffiths, Macquarie University (birds), Dr Steve McLeod, NSW Depart-ment of Industry and Investment (kangaroos).

Throughout most of 2014 Visiting Marie Curie Fellow Dr Mark Cuthbert from Birmingham University, UK was conducting research on the Mountain Front Hydrological Observatory (MFHO) in the Maules Creek catchment in northern NSW. Mark’s research aims at a better understanding of the inter-actions between surface water and groundwater in a semi-ar-id region where ephemeral streams are the main source of groundwater recharge. The timing, rates and climate conditions which control the amount of recharge in these types of envi-ronments are notoriously hard to estimate and there are only a small number of field sites around the world which enable the hydrology of such systems to be studied in such detail. It is hoped that the data from the Maules Creek MFHO will enable better estimates to be made of how groundwater resources are renewed and how climate change might affect water availability in an already water-stressed area. Much of the infrastructure is telemetered and the data can be viewed online at NCRIS data webpage.

Work commenced on the ARC Linkage Project looking at the impact of fire on karst hydrogeology in July, with the arrival of Research Associate Katie Coleborn. In 2014 the project fo-cused on baseline monitoring before control burns planned at two sites with our NSW OEH colleagues, as well as the analysis of data collected at wildfire sites in southwest Western Aus-tralia. The project is supporting several honours students, and has already yielded one submitted paper and a conference presentation at the AGU Fall meeting.

The ARC DP10 Discovery Grant investigating lipid and lignin phenol biomarkers for karst processes concluded in 2014, with postdoctoral researcher Dr Catherine Jex leaving in May to start a new life in Denmark. Dr Jex retains an affiliate status with CWI, and presented the final lipid membrane project results at the AGU Fall Meeting in December. CVEN honours re-searcher Ellen Howley presented the results of her groundwa-ter lignin research. Publications from this project have targeted Organic Geochemistry and further are anticipated through to 2016. Research highlights included the establishment of the lignin phenol methodology at UNSW, and the generation of lipid GDGT and TEX86 biomarker data from soils from region-al cave sites. Extensive fieldwork and associated laboratory analyses focused on the Yarrangobilly site within the Snowy Mountains.

The ARC LIEF grant to procure an isotope ratio mass spec-trometer with high temperature elemental analyser and gas chromatograph has resulted in the procurement of a Thermo DeltaV – GC – HTEA system. This was delivered to the Mark Wainwright Analytical Centre (MWAC) on 30th October and commissioned in November. The instrument is likely to see most use in the analysis of carbon and nitrogen isotopes in organic materials, with extensive interest already from colleagues in the Centre for Ecosystem Science (CES)

River in the Border Rivers region (C. Holley)

Also in 2014 Cameron Holley com-menced his ARC Discovery Early Career Research Project ‘Revitalising Collaborative Water Governance: Lessons from Water Planning in Aus-tralia’. Cameron’s research is trying to answer the questions: What are the best ways to collaboratively govern wa-

ter use? Can community engagement in water governance be reinvigorated? Will it be possible to learn from the failures and successes of surface and groundwater planning to develop more effective, efficient and equitable collaborative governance approaches? And what are the implications of collaborative water governance for regulation and markets? Cameron’s DE-CRA project is answering these questions through his empirical research into collaborative water planning. 2014 was the first year of the three-year project, and involved Cameron complet-ing a substantial portion of his literature review and fieldwork to take a ‘hard’ look at collaborative water governance initiatives in practice. While the project is still in the early stages of its analysis, 2014 saw him publish a paper exploring the possibility of a new collaborative water governance policy option for Aus-tralia (Cameron Holley and Darren Sinclair, ‘Collaborative Water Governance and Audited Self Management: A New Water Pol-icy Option for Australia?’ (2014) 17(2) Australasian Journal of Natural Resources Law and Policy) and deliver a presentation in Glasgow Scotland on crafting collaborative governance sys-tems (ECPR General Conference 2014, 3-6 September 2014). 2014 also saw Cameron receive the prestigious International Union for Conservation of Nature (IUCN) Academy of Environ-mental Law Junior Scholarship Award for his contribution to environmental law scholarship. Cameron received the award in Spain at the Twelfth Annual IUCN Academy of Environmental Law Colloquium.

Cotton Research and Development Corporation Projects

Coal seam gas production well Surat Basin south east Queensland (B. Kelly)

Baselining groundwater chemistry and assessing the potential impacts of coal seam gas (CSG) production in the Condamine Catchment, Qld.

Funded by the Cotton Research and Development Corporation (CRDC). In 2014 Associate Professor Bryce Kelly led research on assessing the potential impacts of CSG production in the Surat Basin on the overlying Condamine River Alluvial Aquifer (CRAA), which is used to supply water for irrigated agriculture. This study consisted of three components: groundwater sam-pling and chemical analyses, a continuous mobile survey of the concentration of methane in the atmosphere, and modelling of historical groundwater hydrograph data.

Dr Dioni Cendon (ANSTO and CWI affiliate) coordinated the groundwater chemical sampling and analyses of 30 irrigation and Qld Government groundwater monitoring boreholes. The main objectives were to provide an assessment of groundwater residence times (groundwater dating), to provide baseline iso-topic and hydrogeochemical data, and to provide an interpreta-tion of hydro-geochemical conditions within the CRAA. Hon-ours students Charlotte Iverach and Lucienne Martel gained extensive sampling experience over the 18 day field campaign.

To fingerprint sources of methane in the landscape, Bryce Kelly and Charlotte Iverach, in association with Royal Holloway, University of London, staff Dr Dave Lowry, Dr Rebecca Fisher, Dr James France and Prof. Euan Nisbet, undertook one of the largest mobile methane surveys done to date in Australia. They surveyed the concentration of methane in the atmosphere in urban settings (Sydney and country towns), adjacent to open-cut coalmines in the Hunter Valley, near CSG developments in the Pilliga and Condamine regions, and in agricultural districts.

Sampling an irrigation bore in the Condamine Catchment (Charlotte Iverach,

Lucienne Martel, Dioni Cendon and Stuart Hankin) (B. Kelly)

Key findings from the surveying are that fugitive emissions of methane associated with CSG production is less than expected (compared to findings in the USA), and that significant methane is offgassing from the co-produced water holding reservoirs. The isotopic signature of the methane plume associated with the co-produced water holding reservoir provides a reference for comparison with methane measured in the irrigation bore water, and assists with attributing the methane in the ground-water as being derived from either microbiological processes in the aquifer or due to the upwards migration of gas from the underlining coal measures.

Mark Hocking, as part of his PhD research, has used a novel impulse response method (Menyanthes) to model groundwater level fluctuations to predict recharge in the Condamine Catch-ment. This work has been submitted to the Journal of Hydrolo-gy. Mark has established different recharge rates under native vegetation, dryland farming and irrigated agricultural regions. The recharge estimates under different landscape settings will help constrain future catchment water balance models, which will examine the impacts of both CSG and irrigation extractions on the sustainable use of groundwater use from the CRAA.

The results of the above projects have been presented to the irrigation community in the Condamine Catchment, and to staff from Qld Office of Groundwater Impact Assessment (OGIA), NSW Office of the Chief Scientist & Engineer and the NSW EPA Office of Coal Seam Gas.

Spatial and temporal importance of diffuse and stream recharge in semi-arid environments: implications for integrated water management (Cotton RDC - scholarship top-up and operating costs).

The scholarship was awarded to Calvin Li. The project aims to quantify aquifer recovery via stream recharge during the transition from drought to a wetter (La Niña) period using NCRIS groundwater infrastructure and publicly available mon-itoring data. It will also assess the importance of groundwater recharge via streams relative to diffuse recharge through the general land surface by developing numerical groundwater and surface water transect models for quantifying groundwater recharge pathways during various climatic and management scenarios. The results will provide groundwater managers with improved data to inform science based policy.

Office of Water Science (Commonwealth Department of the Environment)Research to inform the assessment of ecohydrological responses to coal seam gas extraction and coal mining

Towards the end of 2014 the Office of Water Science commis-sioned a multidisciplinary consortium, led by Griffith University and including the CWI at University of New South Wales, Edith Cowan University, Subterranean Ecology Pty Ltd and Yorb Pty Ltd, to carry out a research program in 2015-2016 focused on “ecology research to address critical priorities concerning ecohydrological responses to coal seam gas extraction and coal mining”.

This project involves an integrated programme of research that addresses key elements within each of four major compo-nents: 1) Ecohydrology of groundwater dependent terrestrial vegetation; 2) Ecological values of baseflow and surface wa-ter-groundwater connectivity regimes in non-perennial streams; 3) Hydrogeochemistry, biogeochemical processes and links to the hyporheos/stygofauna; and 4) Composition and resilience of Great Artesian Basin spring communities. Component 3 is led by Dr Martin Andersen at UNSW.

EU Marie Curie (Dr Cuthbert)Dr Mark Cuthbert completed the Australian part of his out-going EU Marie Curie fellowship in 2014. Mark Cuthbert has been instrumental in setting up the Mountain Front Hydrolog-ic Observatory (MFHO) as part of the NCRIS Groundwater Infrastructure in the Maules Creek Catchment. The MFHO is designed to enable a better understanding of the interactions between surface water and groundwater in a semi-arid region where ephemeral streams are the main source of groundwater recharge. Mark has now collected data on a couple of larger flow events from the MFHO. These results will be written up in several journal papers during Mark’s last EU Marie Curie year at Birmingham University. During Marks time at UNSW he also managed to find time to collaborate with other CWI staff on experiments at Wellington Caves and produced two noteworthy papers in Earth and Planetary Science Letters and Scientific Reports (Nature Publishing). He also published an article on groundwater and human evolution, published in PLOS ONE, featured in Uniken.

IAEA Coordinated Research Project (CRP) – Environmental isotopes to assess groundwater impacts on surface water quality

A joint team from UNSW and Monash University are the official Australian representatives for the IAEA Coordinated Research Project (CRP) entitled “Environmental isotopes to assess groundwater impacts on surface water quality”. This interna-tional coordinated research project under the guidance of the international Atomic Energy Agency (IAEA) was set up with “the objective is to obtain an improved and quantitative understand-ing of how groundwater directly influences the water quality of our river and surface water systems. The CRP is testing proven and novel stable and radiogenic isotopic approaches to assess and map groundwater and surface water connectivity, evaluate the impacts of groundwater discharge on river water flow and quality, and help inform current riverine management models. The CRP is encouraging interdisciplinary nuclear technol-ogy transfer, with the aim to develop diagnostic stable and radiogenic isotopic tools that can be applied in UN Member States for the purposes of solving surface water quality issues involving rivers and streams where groundwater impacts are a factor.” In 2014, Dr Martin Andersen went to the 2nd annual CPR meeting at IAEA in Vienna. Martin got chosen to chair the 4 day meeting and present the meeting conclusions to the IAEA Hydrology section.

NSW Government - RAAP Groundwater Infrastructure and Regulation

This project examines the challenges of monitoring and regu-lating groundwater use. Fieldwork has commenced with water users and regulators. A report to NSW government has been produced on Water Efficiency and Incentive Based Systems, along with one peer reviewed article that identifies barriers to water user support for improved monitoring and makes recom-mendations to enhance their buy-in.

G@GPS Groundwater@GlobalPaleoclimatic Signals

General scientific achievements: The project went through its third year gaining momentum with generic intercontinental cor-relation objectives now on track. The yearly continental focus for 2014 changed from South America to China. This allowed a better use of G@GPS resources and training on a critical new technique for groundwater residence time determinations “age” (81Kr). New basins were incorporated into our network such as the Leizhou Peninsula aquifers (China) and coastal aquifers of SE Bangladesh

Oceania: Intercomparison of groundwater paleoclimatic proxy results at continental scale show parallelisms in coastal areas of SE-Australia with increasing wetter conditions after the Last Glacial Maximum and a peak in wet conditions and recharge between 10 to 7 ka with a progressive drying since 7 ka. How-ever, inland gw data sets have a really subtle response with not much correlation between age and recharge. Detailed work is being carried out in in SW-Australia. The distinctive climatic differences between south-north are also reflected in the gw records but not enough data sets area available from the north of Australia to allow a better description of groundwater re-charge and establish links between the south and north during the Quaternary. Sydney Basin: All results recently analysed in the Sydney basin have been published (Cendón et al. 2014) with more data to be organised for publication. Recent 36Cl/Cl analysis done in 2014 show groundwater ages in the centre of the Sydney Basin that could be close to ~1 Ma but paleocliam-tic implications are complicated by important gas production in underlying Permian formations. Westernport coastal aquifer (Victoria): Following publication of results in 2013 new sam-ples were collected in 2014 and have been analysed. The new

samples are trying to better understand links between seawater level fluctuations and groundwater. We have identified isolated seawater, probably emplaced during higher sea levels. All this information is at present prepared for submission of a MSc thesis that is also being organised for publication. The West Canning Basin (Pilbara): A report was finalised for this portion of the second largest sedimentary basin in Australia. There is an increase of residence times from the recharge areas to the coast with results showing maximum residence times (14C) of up to 20 ka in the more isolated portions of the basin. The water stable isotopes show enrichment along the flow but this has not been linked yet to climatic variables in the area. The isotopic rainout effects and the variability of monsoonal fronts, responsible for effective recharge, maybe too large to produce any time related trends that could be linked to temperature var-iations. We´re exploring 36Cl/Cl and other water-rock interaction processes along the flow path. The main part of the report will be prepared for publication during 2015.

Global intercontinental correlations: The main objective of the project, interpret links between palaeoclimate archives and palaeogroundwater observations at continental and interconti-nental scales, is well underway with one key paper published (Kuss and Gurdak, 2014) showing links between relatively modern groundwater, recharge and climatic fluctuations at USA scale. Two other papers are being drafted at present that will be covering longer time scales and all continents as well as summarise data in the studied basis within the project.

Drip water isotopes in semi-arid karst: implications for speleothem paleoclimatology

This paper reports the results of the first multi-year monitoring and modelling study of the isotopic composition of infiltration waters in a semi-arid karst terrane. The research was funded by NCRIS Groundwater Infrastructure, the NCGRT and an EU Marie Curie Fellowship.

High temporal resolution infiltration rate monitoring was com-bined with monthly isotope drip water and rainfall sampling at Cathedral Cave, Wellington, NSW. Drip water discharge to the cave was shown to occur irregularly, and only after occasional long duration and high volume rainfall events, where the soil moisture deficit and evapotranspiration is overcome. All drip waters had a water isotopic composition that is heavier than the weighted mean annual precipitation, some fall along the local meteoric water line, others trend towards an evaporation water line.

In the paper, we demonstrated that the evaporation of unsatu-rated zone water, as well as the time between infiltration events, are the dominant processes that determine infiltration water isotopic composition. In particular, we demonstrate that the evaporation is coming from water in the subsurface limestone, in addition to evaporation from the soil. Our research highlights the potential significant of sub-surface evaporation, and a method of identifying that it has occurred through the altered infiltration water isotopic composition. The research is relevant to all water limited environments, and has implications for the interpretation of both groundwater and speleothem water iso-

tope records from arid and semi-arid regions.
