Research Themes and Projects

WATER INFORMATICS

Water Informatics is a highly active research area in which computational techniques are applied to a variety of complex problems within various domains including water and wastewater distribution system operation, hydrologic applications, water re-use and recycling, water quality optimisation and the production of decision support tools for the water industry.

Some of the techniques that students of the CDT might seek to employ as part of their research include:

  • numerical modelling (data driven, physically based, mechanistic and including uncertainty estimation, uncertainty and sensitivity analysis, data assimilation, etc.)
  • artificial intelligence and soft computing (tools and interfaces, machine learning, data mining, artificial neural networks, global optimisation, population and evolution-based algorithms, metaheuristics, fuzzy logic etc.)
  • high performance computing (parallel computing, multi-scalar distributed computing, Graphics Processing Unit (GPU) computing, etc.)
  • emerging technologies (cloud computing, smart grids, software as a service, embedded devices, Web of Things, etc.).

WATER SCIENCE AND ENGINEERING

The twenty-first century will be a time of unprecedented change with many global pressures impacting on society and the natural environment. Sustainable management of water resources and water infrastructure will play a key role in supporting the quality of life in the global community. Water research encompasses a large number of science and engineering topics and disciplines for which our Centre partners are recognised internationally:

  • the physical system (flow paths for water through the physical environment of the earth, including: the atmosphere, oceans, coasts, estuaries, rivers, lakes, soils, aquifers, etc.)
  • the biogeochemical system (chemical constituents of water and transformations through macronutrient cycles, contaminants and other chemicals, such as pathogens, pesticides, endocrine disruptors, etc.)
  • the ecological system (life cycles of organisms that are dependent on their habitats, vegetation and the impact of hydrological variation and regimes on the viability of the terrestrial and aquatic ecosystems)
  • the human/urban system (the engineered environment and infrastructure, water use, water resources management, pollution control, river and marine renewable energy, etc.).

COMPLEMENTARY RESEARCH

The challenges that we face in working towards a sustainable water supply for all, environmental protection, and an economically feasible water utility infrastructure require, not only analysis of water informatics, and sound water science and engineering approaches, but also a connection with areas including policy, consumer behaviour, new economic models and ecosystem services.

The WISE CDT consortium can offer research projects in the following areas:

  • statistical analysis (statistical data mining, geo-statistical analysis);
  • social sciences (equity, resilience, justice, ethics, behaviour);
  • economics(financial dimensions, water value, trade-offs and synergies);
  • policy science (social instruments, new markets, water rights);
  • business models for water utilities & markets based on digital services; and
  • complexity science (dynamical systems theory, water and climate, reliability, efficiency).

Examples of past and current student projects include:
