Natural Disasters

Floods

A flood is an overflow of an expanse of water that submerges land. A flood is a temporary covering of land by water not normally covered by water. Flooding may result from the volume of water within a body of water, such as a river or lake, which overflows or breaks levees, with the result that some of the water escapes its usual boundaries. While the size of a lake or other body of water will vary with seasonal changes in precipitation and snow melt, it is not a significant flood unless such escapes of water endanger land areas used by man like a village, city or other inhabited area.

2011 Floods in Sindh

The 2011 Sindh floods began during the Pakistani monsoon season in mid-August 2011, resulting from heavy monsoon rains in Sindh, eastern Balochistan, and southern Punjab.

 The floods have caused considerable damage; an estimated 434 civilians have been killed, with more than 5.3 million people and 1.5 million homes affected.

Sindh is a fertile region and often called the "breadbasket" of the country; the damage and toll of the floods on the local agrarian economy is said to be extensive.

At least 1.7 million acres of arable land have been inundated as a result of the flooding.
