Abstract

 Recently, the number of the breached river levees, mainly due to overtopping, has naturally risen along with the increase in heavy rainfall. It is logically expected that water disasters will typically continue to occur and intensify frequently in the future. Therefore, having a “resilient river levee”, that prolongs the time until the river levee is breached, is necessary. For this, suppressing erosion and suction of the back slope of the river levee against overtopping is important. On the other hand, many scallop shells piled up around fishing ports like Hokkaido, cause environmental problems like a stench. This specific study clarifies experimentally that the crushed shell particles layer established on the back slope of the river levee is effective in suppressing erosion and suction against overtopping.
