3.7 - Bangladesh Flashcards
Bangladesh is in an area prone to
Pressure changes
How does pressure add vulnerability?
1mb drop means 1cm SLR rise
SLR prediction
55cm in 100 years
How does topography increase risk?
Triangular shape bay
Funnels water
Concentrates it
Intensifies tropical cyclones and storm surges
How has physical geography influenced human geography?
Coastal areas mean a port in Chittagong was able to be made
Chittagong now main GDP source, mega city
Tropical cyclones cause what
Intense rainfall
Strong winds (260kmph)
Increased wave height
SLR will result in what if prediction is correct
40% farmland lost
Vital coastal mangrove systems ruined
Delta sediment is
Unconsolidated increasing erosion risk
Bangladesh is how low-lying
Less than 3m above SL
Subsidisation rate
8-18mm/year
Humans have done what to reduce protection
Deforested mangrove forests which would dissipate wave energy from cyclones, erosion from the river delta
River discharge meets
Storm surges
