A user-friendly, inexpensive model interface communicates flood risk-reduction options effectively using realistic interactive visualization

Background/Question/Methods

Extreme precipitation events resulting in flooding are not disasters until people and property are placed in harm’s way. To a large extent, exposure to flood risk is based on choices made by individuals. We conducted Federal Emergency Management Agency (FEMA)-endorsed flood risk management meetings at the local community level. During the meetings we engaged participants in collaborative learning utilizing one of two computer-assisted decision support systems (DSS) to communicate flood risk-reduction options. The two DSS methods were the Multi-hazard Loss Estimation Methodology designed for FEMA and a simpler, more user-friendly method in which participants constructed their own models, making use of realistic interactive visualization.  

Results/Conclusions

Both methods resulted in significant learning outcomes and increased motivation to take action to reduce risk. Also, risk-reduction learning outcomes improved significantly when municipal flood-planning representatives participated in the meetings.
