Modernising Flood Risk Communication with Interactive Visualisations
Flood events pose a significant challenge for many human societies, and one that is expected to increase in both frequency and impact due to climate change. Effective communication of flood risk offers the opportunity to double-check that communities can adapt and respond appropriately to changing local conditions. Yet current flood risk communication practices, especially accessible flood risk maps, frequently fail to communicate risk in an understandable or useful way.
Now, this might seem counterintuitive…
This article explores how modernising flood risk communication through innovative visualisation techniques can dramatically improve community resilience. By identifying the key users of flood risk information and their specific needs, we can develop interactive tools that empower stakeholders to make informed decisions and take appropriate action.
Understanding Critical Flood Risk Visualisation Users
Recent research has highlighted that there are many high-priority flood risk visualisation users who need to be considered when establishing future flood risk communication strategies. These include:
Local Authorities: Responsible for flood management, emergency planning, and community engagement. They need granular, locally-relevant flood data and impact assessments to inform mitigation strategies.
Emergency Responders: Police, fire, and rescue services require real-time flood monitoring, evacuation route planning, and access to critical infrastructure data.
Vulnerable Homeowners: The elderly, renters, and agricultural communities need simplified, actionable flood risk information tailored to their specific needs and vulnerabilities.
Business Owners: Large and local businesses need flood impact assessments to assess business continuity risks and inform business resilience planning.
Communities: Residents require accessible, community-focused flood risk visualisations that build their awareness and empower them to take preparatory action.
Crucially, the research found that the needs of these diverse user groups can be quite different. Whereas local authorities and emergency responders may require highly detailed, technical flood models, vulnerable homeowners and the general public need simple, intuitive visualisations that highlight their personal risk and the steps they can take to become more resilient.
Key Criteria for Effective Flood Risk Visualisation
Workshops with these critical flood risk visualisation users have identified five overarching criteria that future flood risk communication tools might want to address:
-
User-Driven Maps: Provide a range of map types, from simple flood zone delineations to complex hydraulic models, tailored to the specific needs of different stakeholders.
-
Alternative Visualisation Formats: Move beyond static maps to incorporate interactive features, dynamic simulations, social media integration, and other modes of communication that better engage end-users.
-
Consistent Terminology and Definitions: double-check that a common understanding of key flood risk concepts, such as probability, vulnerability, and mitigation measures, across all communication channels.
-
Central Hub of Information: Consolidate diverse flood data sources into a single, authoritative platform that allows users to access the information they need quickly and efficiently.
-
Integration of Local/Community Knowledge: Incorporate granular, community-level data on flood history, mitigation measures, and vulnerable populations to give flood risk visualisations greater local relevance and credibility.
Applying these criteria holistically is crucial for effective flood risk communication, especially for engaging the public. If any of these key elements are missing, flood risk visualisations risk being misunderstood, ignored, or failing to prompt the necessary preparatory actions.
Developing Interactive Flood Risk Visualisations
Leveraging cutting-edge geospatial technologies and participatory design processes, the next generation of flood risk visualisation tools can be developed to meet the diverse needs of critical stakeholders. Some innovative approaches include:
Web-based Flood Mapping: Interactive online platforms that allow users to explore flood hazards, vulnerability assessments, and mitigation strategies at the local level. Functionality could include address-level risk reporting, what-if scenario planning, and links to emergency preparedness resources.
3D Flood Simulations: Immersive, animated models that visualise the dynamics of flood events, from water depth and flow velocities to the inundation of critical infrastructure. These simulations can be particularly effective for emergency planning and public engagement.
Real-time Flood Monitoring: Integrating live sensor data and forecasting models to provide up-to-the-minute flood alerts, road closures, and rescue coordination information directly to responders and residents via mobile apps and social media.
Participatory Mapping: Crowdsourcing local flood knowledge, mitigation measures, and vulnerable populations through interactive web tools and mobile apps. This “bottom-up” data can then be incorporated into official flood risk assessments to improve their accuracy and relevance.
The key is to move beyond static, one-size-fits-all flood maps towards flexible, user-centric visualisations that empower stakeholders to explore, understand, and respond to their unique flood risks. By placing the needs of critical users at the forefront, these innovative tools can dramatically improve flood resilience at the community level.
Overcoming Barriers to Adoption
While the benefits of modernised flood risk communication are clear, there remain several barriers to widespread adoption of interactive visualisation tools. These include:
Technological Limitations: Many communities, especially vulnerable populations, may lack reliable internet access or proficiency with digital technologies. Integrated communication strategies, including traditional media and in-person engagement, are essential to reach all stakeholders.
Data Gaps and Interoperability: Flood data is often siloed across multiple agencies and organisations, making it challenging to consolidate into a coherent, user-friendly platform. Improved data sharing protocols and standards are needed to enable cross-jurisdictional integration.
Institutional Inertia: Entrenched practices and risk-averse mindsets within government agencies and emergency services can impede the adoption of new, unfamiliar communication tools. Dedicated training, leadership, and incentives are required to drive cultural change.
Public Mistrust: Communities may be sceptical of official flood risk information, especially if it contradicts their lived experiences or appears to downplay their vulnerability. Inclusive, transparent engagement processes can help build trust and credibility over time.
Overcoming these barriers will require a multifaceted approach, combining technological innovation, policy reform, and sustained community engagement. But the potential payoffs in terms of improved flood resilience make this a worthy investment for flood-prone communities worldwide.
Conclusion
Modernising flood risk communication through the use of interactive visualisations is a powerful strategy for empowering communities to understand, prepare for, and respond to the growing threat of flooding. By placing the needs of diverse stakeholders at the centre of the design process, these innovative tools can deliver customised, actionable flood risk information that inspires preparatory action and builds long-term resilience.
As we confront the challenges of climate change, the ability to communicate flood risk effectively has never been more crucial. By harnessing the latest geospatial technologies and participatory design approaches, the flood management sector can equip communities with the knowledge and confidence they need to navigate an increasingly uncertain future.
