Empowering citizens to prepare for heavy rainfall events
Situation
Heavy rainfall is one of the most frequent natural disasters in Germany, yet many citizens underestimate their personal risk. Public infrastructure takes years to adapt; individual action can happen right away. What exists today, PDFs, flyers, static maps, isn't personalized and doesn't get anyone to actually act.
Citizens often assume flood protection is solely the city’s responsibility.
Many misjudge their own risk or believe it won’t affect them.
Warnings often come too late. Action must be taken before the rain begins.
Task
Design an engaging and trustworthy civic platform that translates complex flood risk data into an intuitive, personalized experience. The platform needed to build awareness, present city actions transparently, and guide citizens toward protective measures motivating them to act before the rain starts.
Action
We followed a user-centered design process with three phases.
User research
Interviews with citizens and experts revealed awareness gaps, emotional barriers, and behavioral patterns related to risk perception.
Concept development
Multiple ideation rounds led to a validated platform concept focused on hyper-local risk insights and personal relevance.
Design
I designed user flows, UI elements, and interactions to balance clarity with empathy. Color hierarchy and microinteractions were used to gently guide users without overwhelming them. We prototyped and tested iteratively to ensure accessibility, comprehension, and emotional resonance.
Result
Pluvo combines education, localization and empathy to drive awareness and behavior change.
Through a guided, interactive experience, the platform informs citizens of risks, shows protective actions and motivates them with a positive, empowering tone.
Raising awareness in public
Frequently affected or particularly endangered locations in the city are marked to raise awareness and guide people to the digital platform.
Informing personally
Citizens are also informed through personal channels such as letters, especially those in high-risk homes. Staff can now forward people directly to the platform.
Landing page
The landing page introduces the basics of heavy rainfall, explains what the city is doing to protect its residents and emphasizes the importance of personal responsibility. Transparent content creation builds trust, while clear messaging encourages users to take action.
Guiding the user
To make the experience on the platform more personal and guided we implemented two personas. Mona and Tom are there to explain the interface, nudge the user to explore the map and give helpful tips and explanations to make the abstract topic more tangible.
Exploring the map
An interactive city map helps users understand local risks. Blue markers show municipal protection efforts, while flood markers indicate locations of past heavy rain events. Virtual walkthroughs visualize historical water levels to make flood risks more tangible.
Inspecting one’s home
By entering their address, users can explore how city measures affect their home and identify common vulnerabilities. Each potential risk comes with actionable recommendations, from basic structural safeguards to expert contacts for in-depth consultation.
Conclusion page
The final section highlights users’ progress, reinforces key learnings, and offers downloadable emergency resources. Those interested in further support can directly connect with local experts through the platform.
Pluvo earns trust through positive, personal communication and by being transparent about both the dangers and the measures against them.
Learning
My bachelor thesis taught me to trust both the design process and the knowledge I had built throughout my studies. Working independently required confidence in our abilities especially when making key design decisions without constant feedback.
Designing an interactive map and a 3D object was a fun and rewarding challenge. I learned how to use color purposefully, without overwhelming the interface, and how to create a platform that feels intuitive and easy to navigate.
My main responsibilities included the landing page, the conclusion page, and the core UI elements of the map. This experience strengthened my skills in structuring content, defining visual language, and designing for clarity and usability.
