| Research Abstract |
This study aims of clarifying mechanisms of cliff erosion and failure using a geo-centrifuge technique. Physical modelling of these problems at elevated gravities in a centrifuge can increase our understanding, especially for such complex phenomenon. In this study, the effects of cliff geometrical condition and wave condition on mechanisms of erosion and slope failures of the cliff for a short-term problem (likely to storm wave events) was revealed experimentally. Based on the test results, a prediction method for the progress of erosion recession was proposed, and its validity was investigated using the slope stability analysis based on field data.
