A hazard is a sudden event that causes threats to life, property, health and the environment
What is a Hazard?
According to www.stopdisastersgame.org a flood is the unusual presence of water on land to a depth which affects normal activities.
What is a Flood?
Overflowing of rivers
Heavy and prolonged rainfall
An unsual inflow of seawater onto land by hurricanes, high tides, seismic events, tsunamis.
Natural causes of a flood
Dumping of solid waste in solid waste in waterways causing blockage
Deforestation
Construction of temporary dams
Failure of hydraulic and other control structures
Man-made causes of a flood
Destruction of homes and other property
Destruction of crops
Loss of livestock
Physical Impacts of Floods
Causes water-bourne diseases
Loss of livelihood
Mass migration
Causes psycological effects
Social Impacts of Floods
Education is affected
Major contributions to rebuild the economy
Many illnesses causing labour shortage
Affects many economical activities:mining, agriculture, etc.
Economic Impacts of Floods
Sep 12, 2013: MASSIVE flash-flooding took Chaguanas, Curepe, St Augustine, Tunapuna and environs by surprise yesterday, following about two hours of heavy thunderstorms from mid-morning.
Haiti: Floods - Jun 2013: Heavy rains on 14, 15 and 28 Jun 2013 caused flooding in Haiti's Artibonite, Nord-ouest and Centre departments. Six people were killed and over 6,600 families affected. Extensive damage was reported in the agriculture and livestock sectors. It is feared that strategic emergency stocks may be used up early in the rainy season, and it is unlikely that they would be quickly replenished. This could potentially result in large shortages of critical aid supplies, preventing the government and its humanitarian partners from responding effectively to future shocks.
Case studies of Floods in the Caribbean
Mitigation
What is mitigation?• Mitigation refers to any structural or
non-structural measures undertaken to limit adverse hazard.
The heads of the Caricom established the Caribbean Disaster Emergency Management Agency (CDEMA)
There are several types of Flood mitigation • Control over the river• Control over the land• Other measures
Mitigation Strategies used by Caribbean Government
Construction of dams, retention basins or reservoirs on mainstreams or tributaries to excessive water
Levees or floodwalls can be constructed to confine flood waters to a floodways, therby reducing flood damage
Channel improvements
Control over the river
Flood forecasting
Temporary Evacuation
Permanent Evacuation
Flood Insurance
Additional Mitigation Measures
