Recommendation

Iarnród Éireann should develop a documented risk-based approach for flood and scour risk to railway structures through: (1) Monitoring of scour risk at sites through scour depth estimation, debris and hydraulic loading checks, and visual and underwater examination; (2) Provision of physical scour / flood protection for structures at high risk; (3) Imposing of line closures during periods of high water levels where effective physical protection is not in place.
