ABSTRACT
Hydraulic structures, such as sluices, locks, pumping stations, bridges over waterways, and storm-surge barriers may reach their end-of-service if they are no longer economically maintainable or if they can no longer fulfill their functional requirements. Rijkswaterstaat, the executive body of the Ministry of Infrastructure and the Environment in the Netherlands, maintains about 650 hydraulic structures in the country’s main waterway network. This paper describes a unified approach for estimating the remaining service life of hydraulic structures which is being developed and applied in the Netherlands.
