Why does Trinidad flood?
After several hours to several days of rainfall, soils become saturated. At this point, the land is unable to hold any additional water, and rainfall becomes surface runoff. This runoff will raise already swollen watercourses and trigger flash flooding and/or riverine flooding.
What is river flooding?
A fluvial, or river flood, occurs when the water level in a river, lake or stream rises and overflows onto the surrounding banks, shores and neighboring land. In hilly or mountainous areas, floods can occur within minutes after a heavy rain, drain very quickly, and cause damage due to debris flow.
What is flood infrastructure?
By reducing stormwater runoff and protecting floodplains, green infrastructure can help manage both localized and riverine floods. In areas impacted by localized flooding, green infrastructure practices absorb rainfall, preventing water from overwhelming pipe networks and pooling in streets or basements.
What natural disaster happened in Trinidad and Tobago?
On 21 August 2018 Trinidad and Tobago experienced an earthquake in excess of magnitude 6.7 causing damage to some buildings and communication networks. To learn more about what to do before, during and after an earthquake, visit the website of the US Federal Emergency Management Agency.

What causes flood in the Caribbean?
Floods in the Caribbean can often be caused by heavy rainfall, dam or levee failures, tsunamis, unusually high tides, storm surges or burst water mains. Flash floods can occur within a few minutes or hours of excessive rainfall, a dam.
How flooding is caused?
A flood is the accumulation of water over normally dry land. It’s caused by the overflow of inland waters (like rivers and streams) or tidal waters, or by an unusual accumulation of water from sources such as heavy rains or dam or levee breaches.
What are the 4 types of flood?
Different Types of Floods and Where They Occur
- Coastal flood.
- River flood.
- Flash flood.
- Groundwater flood.
- Sewage flood.
What causes a river flood?
Rivers and creeks flood when pulses of rainfall and/or snowmelt move downstream. This causes water to overtop the channel’s banks and spill onto the neighboring floodplain. A natural river channel is shaped by the amount of water and sediment that travels through it.
What is gray infrastructure?
Gray infrastructure refers to structures such as dams, seawalls, roads, pipes or water treatment plants. Adapting to the escalating impacts of climate breakdown — particularly for coastlines facing sea-level rise and stronger storms — requires changing our infrastructure.
What are the methods of flood control?
Some of the common techniques used for flood control are the installation of rock beams, rock rip-raps, sand bags, maintenance of normal slopes with vegetation or application of soil cements on steeper slopes and construction or expansion of drainage. Other methods include dykes, dams, retention basins or detention.
