because water cannot flow up that surface. These are known as “watershed divides”. An example of a watershed is the Etobicoke River Watershed. Streams of water flow downward‚ to form larger streams of water‚ which will eventually lead into the Etobicoke River. The Etobicoke River would then lead into Lake Ontario‚ which would lead the water through the St. Lawrence River‚ opening into the Atlantic Ocean. Everything is in a watershed‚ even your house

expected. Many people lost their lives and property. Australia experienced a flood in Queensland during late December 2010 and January 2011. The devastation of the flood was not expected and many people were caught out in the northern part of the rivers. Both of these floods had similar causes. The impact was different because Pakistan usually floods every year so damages are normally expected. Responses were different due to the country’s wealth at the time. Both countries can implement new policies

Bridges make the situation far more worse cars and trees would get stuck under the bridge. Causes of the Flood Causes of the Bangladesh flood: every year the area has very monsoon rains.

The twelfth largest in length‚ it is‚ for reasons that I examine in the text‚ still surprisingly little known by comparison with other great rivers such as the Nile or Amazon. Yet the Mekong and the lands that lie beside it possess a turbulent history and face major contemporary political social and economic problems‚ and so an uncertain future

Pakistan received more than three times their annual rainfall in a matter of 36 hours. Gushing quickly down the tributaries into the Indus River‚ the rainwater’s gave rise to floods of catastrophic proportions. Given the immensity of the downpours‚ some flooding was inevitable. Yet rivers are essentially channels to drain out water; being one of the largest rivers of the world‚ the Indus should have been able to carry out the excess waters into the Arabian Sea which it joins near Karachi.
