Integral Failure Analysis of Pipelines in Flood Defenses

The presence of pipelines in flood defenses presents a challenge for assessing the probability of flooding. To prevent costly structural measures compensating for the possible negative effects of pipeline failure, we developed a framework for an integral failure analysis of pipeline and dike failure. The assessment framework is based on an event...

Bayesian Inference of Piping Model Uncertainties Based on Field Observations

This paper presents a Bayesian model to determine the model uncertainty of a critical horizontal gradient model for piping for dikes, such a Lane and Bligh. A Bayesian model is needed for two reasons. First, there is a large overlap in cases that failed and survived. Second, the evidence of the failed cases is limited .The model consists of a...

Numerical modeling of small-scale experiments for a coarse sand barrier as a measure against backward erosion piping: (Abstract)

Numerical simulation of the groundwater flow leading to sand boil reactivation in the Po River: (Paper and Abstract)

The reliability of river embankments is essential for flood risk management. The Po River, which flows through the North of Italy, is safeguarded over half of its length by major river embankments. Performance assessment of such water-retaining structures has become a major concern following some significant flood events in the past. Among the...
