…remember ‘still’ floodwaters can be deceptive

By Emergencey Mwale-Kamtande

WATER, a source of life, can transform into a force of destruction when its power is underestimated. 

The prediction by the Meteorological Services Department (MSD) that rains will persist until March, while a source of joy and portending a bumper harvest, brings with it an urgent need for caution. Flash floods, a direct result of these rains, have become a recurring hazard, endangering lives, property and livelihoods.

Floodwaters, even when they appear calm, can be deceptive. They possess a silent ferocity that can claim lives in moments. For instance, a depth of just 25 centimetres of moving water is enough to knock over an adult, 60,96 cm) of water can carry away a vehicle, including SUVs. 

These figures are not just statistics; they are stark reminders of water’s ability to overpower even the strongest individuals or heaviest machinery. Yet, time and again, people take unnecessary risks — attempting to cross flooded bridges, wading through swollen rivers, or improvising makeshift boats — all in the belief that they can overcome water’s strength. Tragically, many of these decisions result in drownings that could have been prevented.

The danger of crossing flooded bridges or submerged areas is perhaps one of the most underestimated risks. When water flows over a bridge or road, it often erodes the structure beneath. What might look like a sturdy surface could be structurally compromised or entirely washed away underneath. 

Drivers attempting to cross such areas often find themselves in life-threatening situations when their vehicles lose traction, stall or are swept away. It is imperative to remember that no journey is worth risking your life for. Turning back or waiting for waters to subside is always the safer option.

For children, the danger is even more pronounced. Children returning from school or playing near water bodies during floods are particularly vulnerable. Their lack of understanding of water’s hidden dangers can lead to tragic outcomes. Rivers and streams that may have seemed safe before the rains can become raging torrents with strong undercurrents during floods. 

Children should never attempt to cross such waters, even if they are in a group. Parents, guardians and schools have a critical role to play in educating children about these dangers, emphasising that no shortcut is worth the risk to life and limb.

The practice of constructing makeshift boats or bridges during floods is another major concern. While these solutions may appear practical in the moment, they are fraught with hidden dangers. Makeshift boats, often crafted from unsuitable materials, lack the stability and buoyancy needed to navigate floodwaters safely. They can easily capsize, leaving occupants at the mercy of strong currents or hidden hazards. 

Similarly, makeshift bridges may not withstand the force of moving water, collapsing under pressure and endangering those who attempt to use them. It is essential to rely on well-constructed, professionally engineered infrastructure and to avoid improvisations that can lead to loss of life.

One of the most insidious dangers of floodwaters lies beneath the surface. Seemingly calm water may conceal strong undercurrents, debris or sharp objects that can cause injury or impede movement. Underwater currents, which are often invisible, can sweep individuals off their feet or trap them against obstacles. Debris carried by floodwaters, including tree branches, metal objects and other detritus, can cause serious injury or entanglement. Additionally, floodwaters often carry contaminants such as sewage, chemicals and bacteria, posing health risks to those who come in contact with them. These hidden threats make it essential to avoid wading into floodwaters whenever possible.

Drowning, a leading cause of death during floods, often occurs because people underestimate the speed and power of moving water. Water flowing at just 5 km per hour exerts a force that is difficult to resist. Even strong swimmers can quickly become overwhelmed, especially in cold or debris-filled waters. 

The human body is simply not designed to withstand such forces, and the outcome is often fatal. Recognising and respecting water’s power is a critical step in preventing these tragedies.

Another aspect of floodwater danger is the unpredictability of flash floods. Unlike gradual flooding, flash floods occur suddenly and with little warning, often catching people off guard. A sudden downpour upstream can lead to a rapid rise in water levels downstream, engulfing roads, homes, and low-lying areas within minutes. The speed and force of flash floods leave little time for escape, underscoring the importance of staying vigilant during periods of heavy rain. 

Listening to weather forecasts, heeding warnings and avoiding flood-prone areas are crucial measures to ensure safety.

Communities must also be cautious about the aftermath of floods. As waters recede, the risks do not disappear. Contaminated water supplies, weakened infrastructure and stagnant pools create new hazards. Drinking water sources may become polluted, leading to outbreaks of water-borne diseases such as cholera and typhoid.

Roads and bridges, compromised by the force of water, may collapse without warning. Stagnant water becomes a breeding ground for mosquitoes, increasing the risk of diseases like malaria and dengue fever.

The  rains, predicted to persist until March, serve as a stark reminder of water’s dual nature both life-giving and life-threatening. Flash floods are a potent demonstration of its power, capable of altering landscapes and claiming lives in an instant. 

The public is urged to treat water with the respect it demands. 

Seemingly calm waters can harbour strong undercurrents, hidden debris and other dangers that are often underestimated until it is too late. Caution must never be thrown to the wind.
