Hazard risks pertaining to partially submerged non-stationary vehicle on low-lying roadways under subcritical flows

Rivers overflowing onto the floodplains can seriously disrupt the transportation system which can cause significant risks to moving or parked vehicles. The major flooding occurrence at the East Coast of Malaysia in December 2014 for instance, exhibited several hazards and fatalities involving vehicl...
