EXPERIMENTAL INVESTIGATION OF DENSITY EFFECT ON TSUNAMI BORE FORCES ON VERTICAL WALLS. (2023). Coastal Engineering Proceedings, 37, structures.89. https://doi.org/10.9753/icce.v37.structures.89
Resumen
In the tsunami generated by the 2011 Great East Japan Earthquake, black tsunamis were identified in many locations. According to Kise and Arikawa (2020), in the areas where samples were obtained, the seawater was found to be mixed with silt components by about 10 percent. They also reported that a large impulsive wave pressure might be generated when the silt-mixed seawater acted on a vertical wall as a bore. Although there have been many studies on the mechanism of impulsive wave pressure in bore-shaped tsunamis (e.g., Co and Yeh, 2018), the effects of sand and silt mixing have rarely been investigated. Therefore, in this research, bore-shaped tsunami pressure experiments with sand and silt in various states of density were conducted to clarify the mechanism of impulsive pressure on a vertical wall and to verify the effect of density on impulsive pressures.Referencias
