How is the water situation in Chennai?

Chennai is supplied 985 mld of water per day against the required amount of 1,200 mld. So water shortage is a perennial problem. The water quality is also not even.

Flood control infrastructure, such as levees, dams, seawalls, and tide gates, work as physical barriers to prevent rising or running water from causing flooding. Other measures, such as pump stations and channels, help reduce flooding.

How does climate change affect flooding?

As warmer temperatures cause more water to evaporate from the land and oceans, changes in the size and frequency of heavy precipitation events may in turn affect the size and frequency of river flooding (see the Heavy Precipitation indicator).
