A flood is an overflow of water tha

A flood is an overflow of water that submerges land which is normally dry.[1] The European Union (EU) Floods Directive defines a flood as a covering by water of land not normally covered by water.[2] In the sense of "flowing water", the word may also be applied to the inflow of the tide. Flooding may occur as an overflow of water from water bodies, such as a river or lake, in which the water overtops or breaks levees, resulting in some of that water escaping its usual boundaries,[3] or it may occur due to an accumulation of rainwater on saturated ground in an areal flood. While the size of a lake or other body of water will vary with seasonal changes in precipitation and snow melt, these changes in size are unlikely to be considered significant unless they flood property or drown domestic animals.
Floods can also occur in rivers when the flow rate exceeds the capacity of the river channel, particularly at bends or meanders in the waterway. Floods often cause damage to homes and businesses if they are in the natural flood plains of rivers. While riverine flood damage can be eliminated by moving away from rivers and other bodies of water, people have traditionally lived and worked by rivers because the land is usually flat and fertile and because rivers provide easy travel and access to commerce and industry.
Some floods develop slowly, while others such as flash floods, can develop in just a few minutes and without visible signs of rain. Additionally, floods can be local, impacting a neighbourhood or community, or very large, affecting entire river basins.

Dej nyab yog ib txeej dej submerges av uas nquag qhuav.[1] Cov European Union (EU) dej nyab tswj nyiaj thiab lub sij dej nyab li ib nplaum los ntawm dej ntawm daim av uas ib txwm tsis kam them los ntawm cov dej.[2] Hauv lub siab "dej flowing", lo lus tej zaum kuj muaj ntaub ntawv rau lub inflow ntawm tom tsim los. Dej nyab yuav tshwm li tus txeej dej ntawm cov dej lub cev, xws li ib tug dej los yog pas dej, uas nyob hauv tus dej overtops los lov levees, uas ua rau ib co dej ntawd escaping nws Area li ib txwm, [3] los kuj vim muaj kev txuam nrog cov rainwater rau hauv pem teb nyob rau hauv ib cov dej nyab areal saturated. Txawm lub me me ntawm ib lub pas dej los yog lwm tus lub cev dej yuav sib txawv raws caij nyoog hloov nag lossis daus thiab daus melt, cov kev hloov loj tsis muaj kev sibkis los yuav tau teeb meem loj ntshe lawv nyab cov cuab yeej los yog poob dej nyeg.
dej nyab tau tus mob nyob hauv lub hav dej thaum tus ndlwg feem coob tshaj li qhov peev xwm ntawm tus hav dej channel, tshwj xeeb tshaj yog thaum khoov rau ob sab los sis meanders nyob hauv lub waterway. Dej nyab ntau ua tsev thiab cov lag luam puas yog hais tias lawv nyob rau hauv tej nras dej nyab ntawm hav dej. Txawm yog muaj dej nyab riverine puas tau eliminated los ntawm kev txav deb ntawm tej dej ntws thiab dej lwm lub cev, cov neeg muaj feeb ntau nyob thiab ua hauj lwm los ntawm cov hav dej vim hais tias lub teb chaws yog li ca thiab fertile thiab vim tus dej ntws tsis muab mus tau yooj yim thiab siv cov lag luam thiab kev lag luam.
ib co dej nyab tsim duj de, hos lwm cov neeg xws li dej nyab eeb, yuav muaj ib txhia feeb thiab tsis muaj cov tsos mob pib tshwm cov nag. Ntxiv thiab, dej nyab yuav hauv zos, impacting ib neighbourhood los yog hauv zej zos, los sis loj heev, rau tag nrho cov dej basins.
