1 1 Significance of the Pakistan Floods of 2010 to America Could it happen here? Michele Seib, CFM Zachary Baccala, CFM

2 Index of Analysis Background of floods along Indus River Hydrology of the Pakistan flood of 2010 Similarities in U.S. Watersheds Hazus Analysis of the Missouri River Impact Study – Could a similar catastrophe happen here? 2

3 Background – Indus River Facts 3 Primary source of agricultural water supply Provides 45% of electricity for Pakistan Majority of population live in the watershed s/01/24/f8/5e/indus-river-and-fields.jpg obtained 5/15/ YKQLSdquC0/TaGEbBL0NfI/AAAAAAAAEbk/RUTiBuswuSU/s1600/Indus +River+Pakistan+by+all+about+pakistran+%252819%2529.jpg obtained 5/15/2011

4 Background – 2010 Flood Facts 4 According to the United Nations OCHA, 17.2 million people directly affected 1,539 lives claimed 1.2 million homes damaged or destroyed 3.2 million hectares of farmland destroyed Damaged 7,820 schools Massive infrastructure damage Photo of flooding in Muzaffargarh (AFP/Getty Images)

5 Background – Planning Factors 5 FLOODING Lack of storage Location of Development Flood warning system Lack of maintenance content/uploads/2010/08/pakistan-flood jpg obtained 05/15/2011

6 Background – Flood Distribution based on: Google Earth and Times Atlas, flooding zones as of http://www.spiegel.de/panorama/0,1518,711885,00.html

7 Hydrology – Indus River 7 Precipitation and temperature primary contributors Links Himalayans and groundwater from Indus alluvium fans Large number of dams and barrages Total Drainage area = 450,000 square miles

8 Hydrology – Flood Disaster Factors 8 Higher than normal precipitation Duration of monsoon season Design Criteria of structures Lack of maintenance content/uploads/2010/11/flood-pakistan.jpg
