FLOOD - A flood is an abnormal progressive rise in the water level of streams or rivers which may result in overflowing. Floods in the Caribbean can often be caused by heavy rainfall, dam or levee failures, tsunamis, storm surges or burst water mains.

Flood Causes

Heavy Rainfall/ Tropical Storms and Hurricanes

It isn’t a secret that hurricanes bring heavy rain and high winds. This heavy rainfall for long periods eventuates in flooding. Hurricanes also cause storm surge, which is totally inundated coastal areas.

Dam or levee failure

Levees are built to prevent water from overflowing certain areas. Unfortunately, over time they can weaken and fail. When they do, the sheer force of the water can often cause more damage than if the dam or levee had not been built.

Human Activity

While flooding is usually a natural occurrence, its effects can be worsened or even caused by various human activities. Construction and development can change the natural drainage and create new flood risks. Deforestation and blocked drains also accelerate flooding.

Burst Water Mains

This continuous flow of water, if not attended to, can lead to the area being submerged.


These large waves bring significant masses of water which can totally flood areas and destroy structures several miles inland.

New land development can increase flood risk, especially if the construction changes natural runoff paths.
In cases of severe flooding, water can take weeks to subside.
Large volumes of water can cause roadbeds to collapse.
Deforestation can cause flooding.
Flooding is the most common natural hazard.
Flash-flooding can occur within minutes.

When soil gets saturated with water, landslides may occur
More people die from drowning in fresh water floods during a hurricane or storm, than from any other cause.
