Global Weather Hazard 
Big Dry Australia
Physical Cause for Big Dry in Australia
El nino
El nino
trade winds die down or reverse direction
warm surface waters move eastward
produces a very dry climate to West Pacific (Australia)
trade winds weaken over warm sea water
causes water to cool and rainfall to decrease
Human causes for Australia Big Dry
population growth in relation with water
Population growth in relation with water
jobs rely on water (e.g. agriculture)
if there is not enough water for the population there is not enough water for jobs
therfore the water the country had when El nino came was not enough which led to the 7 year drought
When was the Big Dry Australia
2002 - 2009
Consequences of the Australia Big Dry
water bill increased by 20% in 2008
dairy farms decreased by more than half
loss of wildlife and biodiversity
grassland turned to scrubland
toxic agal outbreak ruining habitats and environments
less use of hydroelectric power resulting in an increase in the use of fossil fuels which leads to air pollution / enhanced greenhouse effect
Goverment Response to Big Dry Australia
goverment created Murray-Darling Basin Authority
What does the Murray-Darling Basin Authority 
manages the limited water supply
Immediate response to Australia Big Dry
immediate action to maintain service to customers by increasing supplies and reducing water use
