How does the system compare flood levels at different underpasses, and what insights does this provide?
Answer
The system compares flood levels at two underpasses, WRB and FGB, across five rainfall events. Flooding is measured as a percentage of the path level, where 0% represents a dry path.
This comparison provides event-based insight that helps councils:
- Prioritise maintenance.
- Plan upgrades.
- Proactively close paths based on actual risk.
