Civil and Environmental Engineering

Associate Professor in the School of Civil and Environmental Engineering

A/Prof Fiona Johnson is the Director of the Water Research Centre  and is an academic in the School of Civil and Environmental Engineering. She has over 20 years' experience in hydrology working as a consultant, for government and in academia. Associate Professor Johnson’s areas of research and teaching focus on statistical hydrology, particularly with respect to flooding and extreme events and the use of global climate models for climate change assessments of water resources systems. She has a particular interest in solutions to climate and hydrological challenges faced by communities in the Global South.

A/Prof Johnson was a PhD candidate between 2006–10. Immediately after her PhD submission in March 2010, she took up a position at the Australian Bureau of Meteorology as a hydrologist on the Intensity Frequency Duration Revision Project. This project developed revised design rainfalls for Australia, using extended rainfall records and improved statistical methods. A/Prof Johnson played an integral role in the project by applying statistical methods to estimate design rainfalls and provided substantial input into the impact of anthropogenic climate change on extreme rainfalls, contributing to the chapter on this work in the industry guidelines ‘Australian Rainfall and Runoff’.

A/Prof Johnson took up a full-time, ongoing Lecturer appointment in the School of Civil and Environmental Engineering, UNSW, in September 2012 and was promoted to Senior Lecturer in July 2015 and Associate Professor in January 2020.

A/Prof Johnson was appointed as prestigious UNSW Scientia A/Prof for 2019 – 2025. The UNSW Scientia program is one of the cornerstones of UNSW’s 2025 Strategy. Its aim is to attract and retain the best and brightest people, with outstanding research track records. A primary goal of the program is to enhance UNSW research performance by attracting and retaining exceptional researchers at the highest level relative to career stage and supporting them with a unique development and collaboration package and career pathway commitment.

Associate Professor Johnson’s research covers a wide range of disciplines from hydrologic modelling, climate change impact assessment methodologies, applications of remote sensing and statistical analysis of extreme rainfalls. In particular, her research focuses on improving our understanding of hydroclimatological extremes both now and in the future, with her research findings being of particular interest to water managers as they seek to manage risks from hydrological events.

Her research is focused in four main areas:

  • Extreme rainfall analysis and the analysis of extreme rainfalls that are primary driver of flooding. This includes statistical analysis approaches as well as more fundamental research into the atmospheric conditions that are responsible for flood producing rainfalls. 
  •  
  • Methods for improving climate change impact assessments: Johnsons' approach for developing and applying bias correction methods is to focus on the time scales and features of interest for a particular application. In particular she has developed methods for long timescale climate persistence which affect drought risk as well as short time scale rainfall extremes. More recently her research has focused on whether existing hydrological methods are appropriate given non stationarity due to climate change, considering both statistical methods for rainfall analysis as well as hydrological model structures.
  •  
  • The use of satellite remote sensing data to supplement in situ measurements of hydrological proceses
  •  
  • Flood forecasting in ungauged catchments: One of the themes of A/Prof Johnson's research is how flood predictions can be improved in ungauged catchments. This has included analysing the utility of different satellite remote sensing data products including soil moisture, rainfall and water level data. She is currently expanding this research theme to include the use of Numerical Weather Prediction rainfall forecasts.
  •  
  • Humanitarian Engineering: A/Prof Johnson is passionate about ensuring that engineering meets the needs of the most marginalised and remote communities. To date this has included community-centered research in Tanzania, Nepal and the Pacific as well as remote Aboriginal communities in the Northern Territory.
