ERODIBILTY OF UNSATURATED VOLCANIC ASH SANDY SOILS RELATED TO DEGREE OF COMPACTION
The study examined a new erosion control method by considering the erosion effect on a compacted volcanic ash sandy soil. The erodibility of the compacted soil samples with different degrees of compaction and saturation is not fully understood. A series of model flow tests were carried out to understand such process as a first step. It was found that the degree of compaction under different unsaturated conditions with a given grading plays major role for surface erosion protection control. On other hand, in the case of scour of Shirasu soil, a new Erosion Control Apparatus (ECA) was developed to improve the accuracy on scour depth predictions.
