Abstract
Concerns about landslides or dam failures are increasing due to torrential rains, sudden heavy rains, and typhoons caused by global warming. In the 21st century, more than 200 dam and reservoir failures have occurred worldwide, causing enormous damage of human life and property. When a dam or reservoir collapses, a large amount of water and various sizes of earth and rocks are mixed and a debris flow occurs. Debris flows are dangerous because they move quickly and destroy objects in their path. In order to predict the damage caused by these dam and reservoir failures, 3D multiphase flow numerical analysis can be used. This study proposes a downstream risk assessment technique in the event of dam and reservoir failure that predicts downstream damage using a three-dimensional multi-phase flow numerical analysis and evaluates quantitative losses using a building's vulnerability curve against debris flows. This research was supported by Research Program to Solve Urgent Safety Issues of the National Research Foundation of Korea(NRF) funded by the Korean government (Ministry of Science and ICT(MSIT)) (Grant Number : 2021M3E9A1103506)
