Failure paths for levees – A report from ISSMGE TC on Levees

Levee breaches are often the result of a combination of mechanisms, which may happen simultaneously, and/or successively. These interactions are complex and difficult to anticipate in design and assessment as well as during a forensic analysis of an actual breach. The ISSMGE TC201 has published a report on the failure paths (that can also be called failure …

Peat soil – often breaks

https://www.ad.nl/alphen/dijkdoorbraak-zet-weilanden-in-reeuwijk-onder-water-rivierkreeft-zou-niet-de-boosdoener-zijn~af466319/ In the west of the Netherlands a peat “dike” failed today The original soil is the core of the dike, the surrounding soil has subsided and oxidized. The dike probably failed due to the fact it dried out, the recent abundant rainfall is only the trigger. The polder consists of agricultural land

Fusion of information from geophysical and geotechnical investigations for levee assessment

The identification of levees constitutive materials, as well as the detection of possible interfaces and anomalies, are crucial for site characterization. During investigation campaigns, complementary geophysical and geotechnical methods are usually used. These two sets of methods yield data with very different spatial scales and different levels of incompleteness, uncertainty and inaccuracy. On the one …
