Uncrewed Aerial Inspection of Retaining Walls; Smart infrastructure; Evidence synthesis; Asset management; Structural health monitoringAbstract
Uncrewed Aerial Inspection of Retaining Walls is an area of active development in smart and resilient infrastructure engineering,
with evidence that has accumulated unevenly across its component questions. We review the current evidence base for uncrewed
aerial inspection of retaining walls, spanning methodological, implementation, governance, and cost dimensions, focusing on
where practice has converged and where it continues to vary, and set out the practical considerations relevant to an agency
considering its adoption. We conclude that selective, context-specific use is best supported by the evidence currently available,
rather than uniform adoption or avoidance
