報(bào)告簡(jiǎn)介:
Landscapes receive water from precipitation and then transport, store, mix, and release it, both downward to streams and upward to vegetation. How they do this shapes floods, droughts, biogeochemical cycles, contaminant transport, and the health of terrestrial and aquatic ecosystems. Because many of the key processes occur invisibly in the subsurface, our conceptualization of them has often relied heavily on physical intuition. In recent years, however, much of this intuition has been overthrown by field observations and emerging measurement methods, particularly involving isotopic tracers. I will summarize key surprises that have transformed our understanding of hydrological processes at the scale of hillslopes and drainage basins. These surprises have forced a shift in perspective from process conceptualizations that are relatively static, homogeneous, linear, and stationary to ones that are predominantly dynamic, heterogeneous, nonlinear, and nonstationary.
As time permits, I will also outline new methods for quantifying landscapes' nonlinear and nonstationary behavior directly from observational data. These methods reveal that some catchments exhibit much more nonstationary and/or nonlinear behavior than others do. They also show that some catchments exhibit strong spatial heterogeneity in their response to precipitation, resulting from spatial heterogeneity in land use and subsurface characteristics. Results from this approach may be informative for catchment characterization and runoff forecasting; they may also lead to a better understanding of short-term storage dynamics and landscape-scale connectivity.

Zihao Tang is now a Research Fellow at the National University of Singapore. He completed his PhD in Civil Engineering at The University of Auckland, New Zealand, where he specializes in developing scour countermeasures for offshore wind turbine monopile foundations. His research outputs include papers in renowned journals like Coastal Engineering, Ocean Engineering, and the Journal of Hydraulic Engineering. His publications cover topics such as the performance of riprap armouring, collar protection, MICP protection for monopile foundations, hydrodynamic forces and pressure scour of submerged bridge decks, with a strong focus on mitigating the impacts of local scour.
報(bào)告簡(jiǎn)介:
With the thriving of ocean renewable energy, offshore wind energy has been rapidly implemented worldwide. Local scour induced instability of offshore wind turbine monopiles is one of the critical problems. To overcome the scour induced structure failure, various kinds of countermeasures were proposed and tested. Riprap rocks or concrete-made artificial riprap are the most applicable bed armouring methods. To facilitate future design and engineering efforts, new empirical equations were proposed for estimating edge scour depth, subsidence depth, and maximum downstream scour depth, and a novel method is presented for assessing riprap failure under combined vibration and clear water conditions.

The ubiquitous existence of pharmaceuticals in many of our water resources is an emerging global threat with potentially alarming consequences for the health of the public and environment. Pharmaceuticals can enter the aquatic environment through three different routes: inefficient wastewater treatment, improper disposal of unused medicines, and agricultural run-off. Since current wastewater treatments are unable to completely eliminate these compounds, our daily exposure to various drugs and their bioactive metabolites in the environment becomes unavoidable. To ensure water safety, prevention of pollution at the source, complemented with wastewater treatment is key to addressing this problem.
As prevention is the best policy, and because daily exposure to various pharmaceuticals is becoming a reality through water consumption, we must question the most effective way to address escalating global pharmaceutical use. It would be more effective to focus on corrective measures of root causes, rather than simply treating the point where panacea becomes pollutant. Responsible use of drugs and personal care products by individuals is necessary to prevent the introduction of pharmaceuticals to the natural environment. Intensive information campaigns should be launched to educate the public and warn them about each individual’s responsibility and the ecological consequences of drug misuse.
In this talk, I will highlight our expertise on identifying pharmaceuticals and their transformation by-products, their mass flows through time and space, and the new physical and biological balances being temporarily created between living and non-living actors.

Good quality water, essential to sustain human well-being, livelihoods and a healthy environment, is increasingly threatened by a variety of chemicals, called emerging contaminants. Made to aid mankind, but now polluting, emerging contaminants arise from daily anthropogenic practices via domestic, healthcare, agricultural and industrial processes. These pollutants can be pharmaceuticals, hormones and steroids, disinfection by-products, personal care products, flame retardants, agrochemicals (pesticides, fertilizers and growth agents), etc. Because of their rapidly increasing use and incomplete removal in wastewater treatment, these chemicals enter the environment at increasing levels. Understanding how emerging contaminants interact with mineral surfaces will help to assess the fate, mobility and ecological impacts in environmental systems.
Fe- or Mn-oxyhydroxides are generally the dominant redox-active minerals in soils, sediments, and other oxide-rich environments. From an engineering point of view, metal-mediated redox reactions can be potentially applicable for environmental remediation and protection. From an environmental point of view, they can affect a wide range of processes, including biogeochemical cycling and availability of trace elements, degradation of organic matter and transport and mobility of emerging contaminants.
Our research interests focus on combining experimental investigations and modeling in order to improve understanding of surface reactions taking place at mineral/water interfaces. This speech will give some examples of our recent works on the implications of reactive minerals in controlling the fate and transport of emerging compounds in environmental systems.

Poly- and perfluoroalkyl substances (PFAS), a family of over 10,000 chemicals, have become emerging pollutants of global concern due to their widespread usage, ubiquitous environmental presence, extreme persistence, and toxicity. PFAS contain multiple carbonfluorine bonds (strongest bond in organic chemistry) that make them extremely stable. This stability has led to them being called “forever chemicals”. Despite soil’s well-documented role as a global sink and reservoir of PFAS contamination, our understanding of the fate PFAS in soils, their interactions with soil constituents and biota, and potential remediation methods remains limited. Soil largely contributes to the quality of groundwater and crops, which are potential human exposure pathways for these chemicals and, therefore, remediating PFAS contaminated soils is crucial. For this, a deeper understanding of PFAS interactions with diverse soil constituents is crucial for exploring their fate and developing efficient remediation technologies.
We aimed here to: i) Investigate the interactions of PFAS with soil constituents, including both mineral and organic components, alongside co-occurring contaminants. ii) Develop an efficient and cost-effective soil washing strategy designed to separate PFAS from soil. iii) Treat the soil washing effluent through a combination of adsorption integrated with advanced oxidation processes (AOPs) and/or photo-catalysis.
To separate PFAS from contaminated soils, we conducted soil washing with water and/or green extracting agents in combination with innovative air-based foam fractionation technology. Subsequent treatment of PFAS-laden soil washing effluent is then performed by integrating adsorption and degradation technologies (Advanced oxidation or reduction). To couple these processes, dual-functional magnetic materials possessing both functions (adsorbents and catalysts in AOPs) is developed using wastes from the local steel industry and agriculture in the context of circular economy. The treatment of soil washing effluent expands the applicability of this project beyond soil remediation to include water treatment or wastewater management. Meeting these objectives demands advancements in analytics, methods, and experiments, underscoring the need for an interdisciplinary approach. As stringent regulations on PFAS are expected in near future, the present lecture addresses a very timely challenge.
