Probabilistic assessment of inner slope stability in dikes: Gaining insight in the difference between the semi-probabilistic and probabilistic estimates of the reliability index for inner slope stability with overtopping

After overtopping, the most common failure mechanism in the world that leads to a dike breach is the instability of the inner slope. Two stability calculations are required for the semi-probabilistic assessment of inner slope stability. One calculation is without significant overtopping and the other calculation is with significant overtopping...

Analysis of the quantity of CPTs in relation to the inner slope stability

The introduction of the new 'Waterwet' led to the retesting of a lot of primary flood defences within the Netherlands, sequentially certifying a lot of levees as unsafe regarding inner slope stability. To test or design a levee an adequate amount of soil investigation is required to indicate the presence of different soil types, stratification...
