Unveiling the consequences of your breach growth model choice

Within the frame work of the realisation of the ‘Sigmaplan’ for the river Schelde in Flanders (Belgium), a large-scale dike breaching experiment following overflow was held at Lillo (Antwerp) in 2012. The outcomes of the breach test serve to unveil the impact of a chosen breach growth model, to set application limits, to come up with guidelines...

Large scale embankment breach experiments in flume

Embankment breaching is a composite process coupled by hydraulic processes and sediment transport processes. Erosion is the link in the interaction between breach flow and embankment material. Surface erosion starts in the initial breach phase and triggers the initial damage of the embankment. As the surface erosion develops completely, the...

The Thyroid Hormone Receptor Alpha Locus and White Matter Lesions: A Role for the Clock Gene REV-ERB?

Background: Thyroid disorders are associated with an increased risk of cognitive impairment and Alzheimer's disease. Both small vessel disease and neurodegeneration have a role in the pathogenesis of cognitive impairment and Alzheimer's disease. Thyroid hormone receptor alpha (TR?) is the predominant TR in brain. The circadian clock gene REV-ERB...

SWOT analysis of breach models for common dike failure mechanisms

The use of breach models includes two tasks: predicting breach characteristics and estimating flow through the breach. Strengths and weaknesses as well as opportunities and threats of different simplified and detailed physically-based breach models are listed following theoretical and practical criteria. According to the theoretical criteria,...
