“…Probabilistic models have been developed for management and maintenance. When upgrades of large structures are required, an optimisation based on life cycle costs can lead to the selection of a 'future proof ' strategy -see the example of the Afsluitdijk (closure dam) in the next section of this paper and Voortman et al, (2017).…”

“…A rising sea level implies a shorter discharge window and a lower head difference available for discharging excess water from the lake. Indicative calculations show that, due to sea level rise, 40% of discharge capacity has been lost with respect to the situation before 1932 (Voortman, 2017), although the tidal reach has increased (Rijkswaterstaat, Together with the wish to keep the assessment of the impact of river interventions and other changes simple and easy-to-explain, the first alternative turns out to be the most appropriate one. The issue is then to choose the hydraulic conditions under which the impact of interventions and deterioration processes will be assessed, in such a way that the probability of failure is not affected.…”

“…An extensive study was undertaken to find an appropriate way of controlling the lake levels in the future (Voortman & van der Kolk, 2013;Voortman et al, 2017). Important questions in the design of interventions concern the limits of acceptable lake level and the reference year until which a solution should work.…”

“…Several options were analysed in terms of life cycle cost for three scenarios of sea level rise (Voortman & van der Kolk, 2013;Voortman et al, 2017). As part of the life cycle costs, construction, maintenance, renewal and removal costs were considered.…”

This article highlights recent developments in flood risk management in the Netherlands and presents approaches for reliability analysis and asset management for flood defences and hydraulic infrastructure. The functioning of this infrastructure is of great importance for the country as large parts of it are prone to flooding. Based on a nationwide flood risk assessment, new safety standards for flood defences have been derived in the form of maximal acceptable failure probabilities. A framework for the reliabilitybased analysis of the performance of hydraulic infrastructure is introduced. Within this context, various challenges are discussed, such as the dynamic nature of loads, resistance and reliability requirements over time. Various case studies are presented to highlight advances and challenges in various application fields. The first case illustrates how structural health monitoring contributes to a better characterisation of the reliability of the defences and how innovative measures can enhance the reliability. The second case discusses how the river system can be managed in the context of the new safety standards. The third case shows how upgrades and reinforcements of hydraulic structures can be evaluated taking into account (uncertain) future developments, such as sea level rise.
