The context for the research

The\ focus of this research project was informed by the findings of earlier BNHCRC research that investigated human fatalities from natural disasters (Haynes et al., 2017). This project focused on the two behaviours most frequently associated with flood fatalities:

  1. Driving into floodwater in a motor vehicle, and
  2. Recreating in floodwater.

Although there were pockets of information and more detailed knowledge about these behaviours held in some jurisdictions, there was no national picture of either the details surrounding vehicle-related flood fatalities or the incidence of these two general behaviours and the detailed contexts in which the public enters floodwater. Therefore, by studying the general public more comprehensively, there was an opportunity to quantify behaviours and identify the potential challenges and additional levers for communicating flood risk, as well as enabling greater insight into differences across Australia (both within and across jurisdictions).

In addition, the information that was already known about behaviour in floodwater related solely to the general public. Emergency services, in particular State Emergency Services (SES) personnel, were previously identified as an at-risk group for entering floodwater and flood fatalities.

In the context of established approaches to the investigation of risk perception, comprehension, and risk-taking behaviour, SES personnel represent an {\textquoteleft}expert{\textquoteright} group. This meant they could also provide insights about risk perception and risk communication when studied and compared to the {\textquoteleft}lay public{\textquoteright} (expert-novice paradigm), for example enabling identification of differences in use of words/ language, conceptualisation of {\textquoteleft}flood{\textquoteright} and {\textquoteleft}flooded roads{\textquoteright}, and identification and use of environmental cues when judging flood risk.\ 

Finally, as a risk group there is an organisational imperative to study the behaviour of SES personnel entering floodwater when on/off duty. This research supports the evaluation, understanding, and provides opportunities to assist in the mitigation of a range of organisational risks, including

This project commenced in July 2017 and comprised broad two phases:

  1. Understanding behaviour in and around floodwater, and
  2. Collating flood risk communications and co-developing Community Service Announcements (CSAs) for flood for use in National broadcasting by the ABC.

Project strategy for research and collaboration

The research strategy involved a suite of research studies, and employed mixed qualitative and quantitative methods, including experimental research, questionnaires, and in-depth interviews employing a mental models approach to ensure the research problem is well understood, the needs of those at risk could be met, and knowledge is co-produced with end-users and community.

Consultation and collaboration with key stakeholders and various end-users were key aspects of the overall research approach and helped to determine the research foci through the lifetime of the project. Following this collaborative approach, the research was responsive to stakeholder contexts. This enabled the team to take advantage of opportunities to explore some new topics in greater depth (e.g., SES behaviours around floodwater), but has also meant there were some delays and changes to the planned research activities (e.g., being unable to progress some approaches and outputs due to COVID-19). As a consequence, some of the resulting outputs and projects differ to the outputs outlined at the start of the project.

Project overview - extending what is known and addressing the gaps

Previous research has established that floods in Australia are a significant, and often preventable, cause of death, and this research has provided some useful insights to the risk perceptions and planned behaviour among the public in relation to driving and floodwater (Fitzgerald, Du, Jamal, Clark, \& Hou, 2010; Hamilton, Peden, Pearson, \& Hagger, 2016; Haynes et al., 2017).

This project builds on existing knowledge in several important ways:

Overall, these various studies highlight some of the complexity and challenges in flood risk communication and flood risk assessment and factors that need to be considered when developing communication materials. The detailed nature of the data collected also provides insights to how interventions and flood risk communication and engagement work can be targeted.

A snapshot of key findings

As the project\ comprised a number of studies it also generated a substantial number of findings and insights. These have been condensed into a series of practitioner-focused Research into Practice Briefs. In addition, the BNHCRC Communications Team has developed a short series of videos to showcase some key research findings and augment these Briefs.

A snapshot of key findings across the various studies is provided below:

Areas for research utilisation

This\ project provides an in-depth understanding of how the public and emergency service professionals (SES) behave around, and understand the risks of, floodwater. The translation of these findings into utilisation and impact is an ongoing process that will continue beyond the formal end of the research.\ 

There are four main areas of research utilisation that are being pursued:

In addition\ to the above areas of potential and emerging utilisation, the project team has worked actively with end-users and a range of additional stakeholders to co-produce project outputs, including conference presentations (Taylor, Wiebusch, Tofa, Haynes; AFAC 2019) and co-authored peer-reviewed articles (Taylor, Tofa, Haynes, McLaren, Readman, Ferguson, Rundle, Rose, 2019).

Research Capacity Building

The\ research project team has also supported research capacity building through the mentoring and inclusion of students in research activities, including a successful PhD completion (Ahmed, 2019), five Masters of Organisational Psychology students, two psychology honours students, and a number of short-term research and engagement placements. The project funding has supported early career researchers (ECRs) and has enabled these ECRs and students to progress through co-authored peer-reviewed publications and utilisation outputs, i.e., Research into Practice Briefs.
