What is a Hazard? • A hazard is a sudden event that causes threats to life, property, health and the environment
What is a Flood? • According to www.stopdisastersgame.org a flood is the unusual presence of water on land to a depth which affects normal activities.
Causes of a flood • There are two causes of floods: • Natural causes • Man-made causes
Natural causes of a flood • Overflowing of rivers • Heavy and prolonged rainfall • An unsual inflow of seawater onto land by hurricanes, high tides, seismic events, tsunamis.
Man-made 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
Impacts of floods • There are three types of impacts of floods • Physical • Social • Economic
Physical Impacts of Floods • Destruction of homes and other property • Destruction of crops • Loss of livestock
Social Impacts of Floods • Causes water-bourne diseases • Loss of livelihood • Mass migration • Causes psycological effects
Economic Impacts of Floods • Education is affected • Major contributions to rebuild the economy • Many illnesses causing labour shortage • Affects many economical activities:mining, agriculture, etc.
Case studies of Floods in the Caribbean • 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.
Mitigation What is mitigation? Mitigation refers to any structural or non-structural measures undertaken to limit adverse hazard.
Mitigation Strategies used by Caribbean Government • 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
Control over the river • 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 land(land use Policies were developed) • Zoning • Subdivision Regulations • Building Codes
Additional Mitigation Measures • Flood forecasting • Temporary Evacuation • Permanent Evacuation • Flood Insurance
