Hazard Definition of a Flood Causes of a Flood Impacts of a Flood Case studies of floods in the Caribbean Mitigation strategies by Caribbean Government

 A hazard is a sudden event that causes threats to life, property, health and the environment

 According to a flood is the unusual presence of water on land to a depth which affects normal activities.

 There are two causes of floods:  Natural causes  Man-made causes

 Overflowing of rivers  Heavy and prolonged rainfall  An unsual inflow of seawater onto land by hurricanes, high tides, seismic events, tsunamis.

 Dumping of solid waste in solid waste in waterways causing blockage  Deforestation  Construction of temporary dams  Failure of hydraulic and other control structures

 There are three types of impacts of floods  Physical  Social  Economic

 Destruction of homes and other property  Destruction of crops  Loss of livestock

CCauses water-bourne diseases LLoss of livelihood MMass migration CCauses psycological effects

 Education is affected  Major contributions to rebuild the economy  Many illnesses causing labour shortage  Affects many economical activities:mining, agriculture, etc.

 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.

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

 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

 Zoning  Subdivision Regulations  Building Codes

 Flood forecasting  Temporary Evacuation  Permanent Evacuation  Flood Insurance
