The 4th International Conference on
Water Resource and Environment (WRE 2018)
Keynote Speakers
Prof. Tianfu Xu
College of Environment and Resources, Jilin University, Changchun, Jilin 130021, China

Tianfu Xu is currently a chair professor at Jilin University of China. He has been working at Lawrence Berkeley National Laboratory (LBNL) of USA for 16 years, in which he joined in 1996, initially as post-doctoral fellow, then become a scientist, and staff scientist. He received a bachelor’s degree in 1984 from Jilin University, an M.S. degree in 1993 from Delft University of Technology of The Netherlands, and a Ph.D. in 1996 from University of La Coruña, Spain. For the last 25 years, Tianfu has been working on developing new approaches to modeling multiphase non-isothermal fluid flow and chemical transport in unsaturated and saturated porous media and fractured rock systems. He is the chief developer of LBNL’s multi-phase non-isothermal reactive flow and chemical transport simulator TOUGHREACT. The program is widely used internationally for geothermal energy development, CO2 geological sequestration, nuclear waste disposal, environmental remediation, and increasingly for petroleum applications. Tianfu has authored and co-authored about 70 peer-reviewed journal papers. His papers have been cited by other researchers more than 4000 times (SCI citation).

Speech Title: Subsurface Reactive Transport Modeling: Applications to Energy and Environment Problems

Abstract: The assessment of waste disposals, the study of groundwater pollutions, and the understanding of natural groundwater quality patterns require reactive transport modeling (RTM) to consider both the transport of heat and dissolved species as well as their complex interactions with the solid (or other) phases of the engineering barriers and geological formation. The RTM is a necessary tool for analyzing, evaluating, and predicting subsurface coupled processes of physics, chemistry and microbiology in the shallow earth system. In the past several decades, a number of methods and techniques have been developed to address this complex issue. This talk will briefly review the theory and method of the RTM. Then, couples of examples regarding the groundwater quality occurrence, CO2 geological storage, geothermal energy development, and submarine biogeochemical processes will be presented.

Speech Title: Advances in Seasonal Streamflow Forecasting

Abstract:Each month, the Australian Bureau of Meteorology issues operational seasonal streamflow forecasts of total water volumes for three months ahead for over 200 locations across Australia (http://www.bom.gov.au/water/ssf/). The forecasts are created using modelling approaches developed by the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and other partners. Forecasts of seasonal streamflow can inform tactical management of water resources, allowing water users and managers to plan operational water management decisions and assess the risks of alternative water use and management strategies.
Forecasting streamflow over the next month, season and multiple seasons is a challenging task, because the predictability of climate over these forecast horizons is low. On the other hand, initial conditions of soil moisture, groundwater and other water stores in a catchment can have some relatively predictable effects on streamflow months ahead. State-of-the-art forecasting methods aim to (1) quantitatively capture, as much as possible, both sources of streamflow predictability and (2) statistically represent the remaining predictive uncertainty in a reliable manner.
In this presentation, I will give an overview of scientific approaches for seasonal streamflow forecasting, research progress made in Australia in improving the skill and statistical reliability of ensemble forecasts, and the HEPEX (https://hepex.irstea.fr/) international testbed initiative. I will also share Australian experience in using seasonal streamflow forecasts for water management.

Speech Title: Survival of Bacteroidales in Stream Water and Sediment

Abstract:Amplification of host-associated gene fragments of fecal Bacteroidales using quantitative PCR (qPCR) is a widely used approach for fecal source identification. Since PCR cannot discriminate between DNA derived from live and dead cells, PCR-based methods may overestimate fecal Bacteroidales populations in the environment. This can be addressed by using propidium monoazide (PMA) as a DNA intercalating agent to differentiate DNA from live and dead cells. In this study, PMA-assisted qPCR was used to determine the survival of viable Bacteroidales in stream water and sediment microcosms spiked with sewage samples. About 50% of the total Bacteroidales in the sewage can be attributed to dead cells or extracellular DNA. Microcosm experiments revealed that the persistence time for total viable Bacteroidales, as measured by the time to decline by 99%, was about 2 days in stream water and 5 days in sediment. In contrast, the persistence time for E. coli was about 5 days in stream water and 19 days in sediment. Our results suggest that detection of Bacteroidales by PMA-assisted qPCR provides information about recent fecal pollution in surface waters.
