Most disastrous floods occurred in different parts of India

This is a list of notable recorded floods that have occurred in India. Floods are the most common natural disaster in India. The heaviest southwest, the Brahmaputra, and other rivers to distend their banks, often flooding surrounding areas. [citation needed]

## In the 20th century

[edit]

* In 1923, Lucknow was one of the earliest recorded floods in the city's history. It was caused by heavy rainfall in the monsoon season, which made the Gomti River overflow its banks and inundate many parts of the city. The flood affected the old city, the civil lines, and the cantonment areas. It damaged property, crops, and infrastructure, and forced many people to take shelter in higher places. The flood also disrupted the communication and transportation systems, and posed a threat to public health and safety.[1]
* In October 1943, Madras (now Chennai) saw the worst flood to hit the city. Flood occurred due to excessive rains that lasted for 6 days and overflowed Coovum and the Adyar rivers. Damage caused to life and property was immense. However, estimate figure is unknown. The flood left thousands of people homeless.[2]
* In 17 October 1960, The 1960 Lucknow flood was a natural disaster that occurred in the city of Lucknow, the capital of Uttar Pradesh, India, in October 1960. It was caused by the overflow of the Gomti River, a tributary of the Ganges River, after heavy rainfall in the Himalayan region. The flood submerged almost half of the city under several feet of water, killing more than 16 people and making thousands homeless on 13 October 1960. It was one of the worst floods in Lucknow's history.

The flood affected various parts of the city, including the old city, the civil lines, the cantonment, and the main shopping centre. It also caused damage to the electricity supply, the zoological gardens, and many historical monuments. Elephants, bicycle rickshaws, and boats were used as means of transport in the flooded areas. The government deployed army units and helicopters to rescue the marooned people and provide relief materials. The water level dropped very slowly and no estimate was made of the total damage. The flood also coincided with a tidal wave that ravaged the mouth of the Ganges in Bangladesh, killing more than 3,000 people on 16 October 1960. The Gomti River, on which Lucknow is situated, is a northern tributary of the Ganges River.[3]

* In 8 September 1971, The 1971 Lucknow flood was a natural disaster that occurred in the city of Lucknow, the capital of Uttar Pradesh, India, in September 1971. It was caused by two breaches in the embankment of the Gomti River, which flows through Lucknow before joining the Ganges River. The breaches were caused by the high water level of the river, which was six feet (about two metres) above the danger mark due to heavy rainfall in the monsoon season.

The flood submerged many parts of the city under three or four feet (one to 1.2 metres) of water, affecting the main shopping area, some fashionable residential areas, and the zoological gardens. The flood also disrupted the electricity supply, the communication and transportation systems, and the public health and safety. At least 13 deaths due to drowning were reported from Uttar Pradesh on September 7, taking the death toll in two months of rains and flooding in the state to 268. In Lucknow itself, a quarter of the city's area was under water on September 8. The government deployed army and civilian engineers to plug the breaches in the embankment and rescue the marooned people. More than 25,000 people were evacuated from the city in 24 hours and housed in 18 camps opened by the state government. Elephants, boats, and helicopters were used as means of transport and relief in the flooded areas. The flood also affected the animals in the Lucknow Zoo, some of which had to be placed on raised platforms or protected by sandbags and boulders.[4]

* On 11 August 1979, the Machchhu-2 dam situated on the Machchhu River burst, thus flooding the town of Morbi in the Rajkot district of Gujarat.[5] Exact figure of loss of lives is unknown, but it is estimated between 1800 and 2500 people.[6][7][8]
* In 1987, Bihar state of India witnessed one of its worst floods till then. Flood occurred due to overflow of the Koshi river; which claimed lives of 1,399 humans, 302 animals and public property worth INR ₹68 billion (US$810 million).
* In 1988, Punjab experienced its first flood when all the rivers in Punjab overflowed.
* In July 1993, flash floods killed 530 people across the seven to eight states of India.

## In the 21st century

[edit]

* Heavy rains across the state of Maharashtra, including large areas of the metropolis Mumbai which received 567 (tmkoc inches) alone on 26 July 2005 killed at least 1,094 people. The day is still remembered as the day Mumbai came to a standstill, as the city faced worst ever rain. Mumbai International Airport remained closed for 30 hours, Mumbai-Pune Expressway was closed for 24 hours with public property loss was estimated at ₹550 crore (US$66 million).
* The 2008 Lucknow flood was a natural disaster that occurred in Lucknow, the capital of Uttar Pradesh, India, in August 2008. It was caused by the overflow of the Gomti River after heavy rainfall in the monsoon season. The flood submerged several parts of the city, affecting more than 100,000 people and killing at least 15. The flood also damaged property, crops, and infrastructure. The state government declared Lucknow as one of the 11 districts affected by floods and deployed army units and helicopters to rescue and provide relief to the affected people. The rainfall increased the water level of the Gomti River, which rose above the danger mark of 8.5 metres (28 ft) at Lucknow. The river also received water from its tributaries, such as Sai, Kathana, and Kukrail. The flood situation was worsened by the inadequate drainage system of the city, which could not cope with the runoff from the urban areas. The encroachment of floodplains and wetlands by illegal constructions also reduced the natural capacity of the river to absorb excess water. The flood affected various parts of Lucknow, especially the low-lying areas along the banks of the Gomti River. The worst-hit areas were Daliganj, Nishatganj, Aminabad, Chowk, Thakurganj, Alambagh, Rajajipuram, and Indira Nagar. The flood water entered many houses, shops, offices, schools, hospitals, and religious places, forcing people to evacuate or take shelter on rooftops or higher grounds. The flood also disrupted the power supply, water supply, communication, and transportation systems in the city. Many roads and bridges were damaged or submerged by the flood water, making them impassable for vehicles and pedestrians. The flood also posed a threat to public health and safety due to water-borne diseases and electrocution.[9][10]

## Climate change

[edit]

Climate change is said to have in part caused (but may also be a natural evolution of earth's cycle) large-scale floods across central India, including the Mumbai floods of 2006 and 2017. During 1901–2015, there has been a three-fold rise in widespread extreme rainfall events across central and northern India – Gujarat, Maharashtra, Madhya Pradesh, Chhattisgarh, Telangana, Odisha, Jharkhand, Assam and parts of Western Ghats – Goa, north Karnataka and South Kerala.[24] The rising number of extreme rain events are attributed to an increase in the fluctuations of the monsoon westerly winds, due to increased warming in the Arabian Sea. This results in occasional surges of moisture transport from the Arabian Sea to the subcontinent, resulting in heavy rains lasting for 2–3 days, and spread over a region large enough to cause floods.[24][25]
