Floods - Coggle Diagram

- - - - how long the rain event
    - - How many times the rain event occurs
    - - mm/h
- - - - Water supplies contaminated due to chemical spills from factories and sewage
      - Exposed to contaminated water and diseases such as cholera and dysentery will spread
      - May spread and affect a larger population
      - Stagment pools -> floodwater -> encourage mosquitoes to bread -> more cases in maleria and dengue
    - - Evacuate to emergency shelters
      - Stay in emergency shelters -> long period of time after flood while trying to rebuild houses
      - Flood water -> property damage or even sweep houses away
    - - Injuries by obj and debris washed by fast- moving floodwaters
      - Floodwaters may cause building to collapse and injure or kill people
      - Injuries, spread of diseases and loss of lives
      - People caught in flood for long time -> suffer Hypothemia -> effects: confusion, shivering, loss of coordination
    - - The supply of clean water -> disrupted -> damage water pipes
      - Sewage pipes burst -> sewage flow and contaminate water supplies
  - - - Transport infrastructure -> facilities such as roads and railway tracks
      - Floods, transport infrastructure can become impassible -> submerged or damaged
    - - Disruption of electricity supplt can affect capacity of factories and companies to produce goods and services
      - Power lines can be damaged and power outage may occur during floods
      - Floods, disrupt supply of energy by affecting its distribution
    - - Flood damage machinery and equipment such as drilling machines, cranes, com
      - Machinery and equipment may be submerged in water and cuz damage to motors and other electrical component
- - - - Raised river banks (sides of river) -> only for river
        Man made
    - - Barriers against (coastal/river) floods
        man-made
        
        Can be used together to prevent water from exceeding the carrying capacity of the canals/ river channels
        prevent water from overflowing to usually dry areas
    - - A way which plans the physical development of land and its uses. Usually zoned as low-value development such as parks and fields so to suffer fewer economic losses
    - - Monitoring changes and make a forecast. A forecast is a statement bout the way things will happen in the future. If situation is serious, a warning will need to be issued
    - - Minimum platform level.
    - - Evacuating a large amount of people in a short time. Therefore, drills are a form of preparedness meassure where people practise the steps to leave a place safe and orderly way in an emergency
    - - Changes made to river channel or canal to increase its capacity to hold water or enable the water to flow quickly
