INTERNAL EROSION RESEARCH

However, these earth structures can suffer from instabilities, potentially leading to breaches. Several statistical analyses (Foster et al. 2000 ; Fry et al. 2015) showed that more than 90% of these instabilities are due to erosion processes, among which internal erosion. Moreover, risks related to internal erosion in dikes are more difficult to manage as soils may be insufficiently compacted and/or strongly heterogeneous.
