Flood is considered as one of the most devastating and frequent disaster all over world as it claimed huge loss of life and economic damage which put heavy burden than other disasters on economy. Floods are recurrent phenomena in India. Flood incidences are increasing very swiftly and its causes are climatic change, tsunami, cloud bursting, massive rainfall, intense tropical cyclone, changes in catchment areas such as deforestation, silting, poor river management, urbanisation which result in high run-off, etc. India has been experiencing this disaster very often. Global warming accelerates the melting of glaciers in the Himalayan region. The rapid glaciers melting will increase the risk of brusting of high altitude glacial lakes such as the flash floods disaster witnessed in 2013 in Kedarnath and in 2021, in Chamoli district of Uttarakhand. Floods cannot be completely stopped but with advancement of science and technology their effect can be reduced. Heavy rainfall during the first week of the September 2014 resulted in massive flooding in the former state of Jammu and Kashmir which witnessed the worst floods in the last six decades. No doubt the sudden massive precipitation was the main cause of unprecedented flooding but other factors such as rapid urbanization, growing built-up area, disappearance of wetlands, large-scale encroachment along the bank of rivers, degradation of productive agricultural land, forested areas and green spaces etc. have aggravated the flood problem which otherwise absorbs the flood water as they acted as sponges during the floods.
