Pakistan 2010 River Case Study Flashcards
What was the dates of the flooding in Pakistan
26th July 2010 until August 2010
What where the most affected areas in Pakistan
The areas of the central and southern regions of Punjab, Sindh and Baluchistan provinces
What was the same of the River that flooded
River Indus
Physical. Describe the affects of the higher than normal temperatures
Higher than normal temperatures that caused snowmelt in the Himalayan Foothills, this water fed the River Indus
Physical. What were the type of rains
Monsoon rains
Physical. What was the experience of the summer monsoon rains and what happened rainfall levels
The wet summer monsoon rains that were experienced were particularly intense and resulted in rainfall being twice the average rainfall for July and august
Physical. Where did the wet summer monsoon rains extend further over
The wet summer monsoon rains extended further NorthWest across Pakistan than usual
Physical. What was the result of the monsoon rains extending further northwest where did this add water to
This resulted in the Northern State of KPK and Swat Valley receiving unexpected intense flash floods which added a huge deluge of water into upper tributaries
Human. What was the rate of deforestation
2% deforestation per year
Human. What affect did the increased rate of deforestation have on soil and river bank erosion
There was an increased rate of soil and river bank erosion, therefore decreasing the capacity of the river channel and there was less interception meaning water reached the channel at a faster rate, causing flooding
Human. How many canals, barrages and channels where poorly maintained (what where these the source of) and what resulted from this
1000km of canals, barrages and channels were poorly maintained and these where the source of water irrigation but they ended up choked with silt
Human. What is irrigation
Irrigation is the practice of applying controlled amounts of water to land to help grow crops
Human. Describe the characteristic of the Indus River and the impact that the loss of discharge had on it
The river Indus is a sediment rich river, and the loss of discharge man there was less energy to transport the sediment downstream to deltas and floodplains
Human. What is the population of Pakistan and what pressures does this come with
Pakistan has a population of 191 million people, increasing by 3 million each year. With this there is a high pressure to protect homes and buildings from floods
Human. What happens when levees are breached
The flood waters are trapped on the floodplain due to the levees and water can’t get back into the river so floods are prolonged
