Question

what are the consequences of overdrawal of water​

Answer 1

But over-pumping can lead to even more serious problems if the excessive extraction takes place over a long period of time – including the lowering or sinking of the land surface, which is called land subsidence, and, in areas along the coast, sea water intrusion.

Answer 2

An over-withdrawal of water can have many consequences, the chief one can be lowering of the water table in a region. As the water table goes low, water may not be easily obtained leading to it scarcity.

Overdrawal of water can also lead to sinking or lowering of the land surface that can make it prone to flooding. Streams and water bodies may also get disconnected due to over-withdrawal of water.
