Quick Answer
Following a river during a flood poses risks such as being swept away by powerful currents, drowning, or being trapped underwater. The water's velocity and depth can be unpredictable, making it challenging to navigate. Moreover, the river's banks may be unstable or flooded with debris.
Unpredictable Currents
When a river is flooded, its current can become extremely powerful, capable of sweeping a person away in a matter of seconds. According to the National Weather Service, floodwaters can move at speeds of up to 15 miles per hour, which is faster than a person can swim. In addition, the water’s surface may be turbulent, making it difficult to gauge the current’s strength.
Hidden Hazards
The river’s banks and surrounding terrain can be treacherous during a flood. Trees and power lines may be uprooted and submerged, while rocks and other debris can be hidden beneath the surface. In a study by the Federal Emergency Management Agency (FEMA), it was found that 75% of flood-related deaths occur in vehicles or while attempting to cross flooded areas.
Essential Precautions
If you must navigate a flooded river, it’s essential to take specific precautions to minimize the risks. Wear personal flotation devices (PFDs) and stay close to a safe anchor point, such as a tree or a rock. When walking through flooded areas, keep your feet wet, as water is less conductive than electricity. Additionally, never attempt to drive through flooded roads or areas, as the water may be deeper than it appears.
