Numerical assessment on floating stability limits for static vehicle under partial submergence
Large debris including vehicles when swept by floods could threat people�s life and damage properties. Concerning vehicles in floodwaters, their stability remains a challenge to the research world, particularly the buoyancy depth and the parameters affecting them to float. Therefore, a detailed inve...
