Floods - Coggle Diagram

- - - - Leads to decreased infiltration, increased surface runoff, leads to flooding)
  - - - Ineffective canals/drains leads to floods (e.g: AYE flood in SG)
- - - - -Quick rise in water level
        
        -Very sudden and over a short duration
    - - -Occurs at coastal areas
        
        -storm surges (strong winds, tsunamis)
    - - -Occurs in floodplains, low-lying areas
        
        Exceeds channel capacity which causes overflowing(Floods)
  - - - -Dams, floodwalls and leeves
        
        This leads to an increased amount of water which leads to overflowing. Lack of maintenance leads to dams etc bursting
    - - -Intensity, duration and frequency
        
        Frequency: When there is higher frequency, higher chances of floods
        
        Duration: Longer duration, more amt of water, higher chances of floods
        
        Intensity: Higher intensity(thunderstorms)
    - - When seasons change( winter to spring), Snow melts and there is an increased amt of surface runoff, leads to floods
- - - - water-borne
        
        Water pipes damaged by floods, leads to contaminated water sources, leads to Cholera and Dysentery
      - Mosquito-borne
        
        Stagnant pools of water causes mosquito breeding, leads to Dengue and Malaria
  - - - People are unable to go to work, lower income
      - Airports are affected, tourists are unable to come, lower economy
    - - Unable to obtain petrol, unable to transport goods, lower economy/revenue
      - Electricity gets affected, lower production of goods, lower revenue/profits
