Question

tell me why flood occured in kerela recently? give geographical region?

Answer 1

Kerala, which lies in the tropic region, is mostly subject to the type of humid tropical wet climate experienced by most of Earth's rain forests. Meanwhile, its extreme eastern fringes experience a drier tropical wet and dry climate.

Answer 2

Kerala received heavy monsoon rainfall, which was about 256% more than the usual rain fall in Kerala, on the mid-evening of August 8, resulting in dams filling to capacity; in the first 24 hours of rainfall the state received 310 mm (12 in) of rain.[20] Almost all dams had been opened since the water level had risen close to overflow level due to heavy rainfall, flooding local low-lying areas.[21] For the first time in the state's history, 35 of its 54[16] dams had been opened.

The Government of Kerala argued in the Supreme Court that the sudden release of water from the Mullaperiyar Dam by the Tamil Nadu government was one of the reasons for the devastating flood in Kerala.[13] The Tamil Nadu government rejected the argument, saying that Kerala suffered the deluge due to the discharge of excess water from 80 reservoirs across Kerala, spurred by heavy rains from within the state; It also argued that the flood surplus from the Idukki dam is mainly due to the flows generated from its own independent catchment due to unprecedented heavy rainfall, while the discharge from Mullaperiyar dam was significantly less. Though it is difficult to attribute any single event to climate change, its possible role in causing the heavy rainfall event over Kerala cannot be ruled out
