A system perspective on flood risk in polder drainage canal systems

A major part of the Netherlands is prone to flooding: roughly 60%. Therefore, a large system of flood defences protects the country from flooding. These flood defences are divided into primary and regional flood defence systems. Primary flood defences protect areas against catastrophical flooding events from the sea, big lakes and major rivers,...

Reliability updating for slope stability: Improving dike safety assessments using performance information

Dikes are crucial for the protection against floods. One of the ways in which dikes can fail is by the instability of the inner slope. Credible probabilities of failure for slope stability are essential for the safety assessment of existing dikes and the design of dike reinforcements. This dissertation focuses on improving failure probability...

A Metamodelling Approach to Reliability Updating with Dike Construction Survival

The construction of a dike improvement often causes a decrease in reliability during construction. Raising a dike may give rise to excess pore water pressures in the subsoil, resulting in a temporal strength decrease. Observing the survival of such a loading condition might provide information on the strength of a dike. Therefore, this research...
