Issue• The Netherlands has a complex network of waterways, with many
and different types of hydraulic structures. A lot of these structures are nearing the end of their lifetime in the coming decades, making replacement or renovation necessary.
• The existing structures have to be redesigned to meet the challenges of future developments and service demands of future generations.
• This stresses the importance of an integral maintenance and development strategy at the network level.
Approach• This asks for a learning and interactive process with early
stakeholder involvement.• New functionalities, changing performance requirements,
uncertainties in climate and socio-economic developments all influence the need and timing of the renovation or replacement, and should therefore also be considered.
• Adaptive Delta Management is a method that incorporates future uncertainties. This supports a transparent decision making process and uses so called ‘adaptation pathways’.

Discharge sluice and pumping station IJmuiden Source: Rijkswaterstaat
Functions: Discharge- and pumping capacity of the hydraulic structures in the water system.
End-of-life: prediction end-of life of the hydraulic structures, based on founding year + design lifetime.
