Banjir adalah peristiwa yang terjadi ketika aliran air yang berlebihan merendam daratan. Banjir diakibatkan oleh volume air di suatu badan air seperti sungai atau danau yang meluap atau menjebol bendungan sehingga air keluar dari batasan alaminya.
Banjir juga dapat terjadi di sungai, ketika alirannya melebihi kapasitas saluran air, terutama di kelokan sungai. 


Penyebab terjadinya banjir bisa dari alam  atau pun akibat tangan manusia , jika dari alam biasanya karena sungai Endapan dari hujan atau pencairan salju cepat melebihi kapasitas saluran sungai. Sedangkan dari tangan manusia
Kerusakan akibat aktivitas manusia, baik disengaja atau tidak merusak keseimbangan alam

Dampak yang ditimbulkan oleh banjir terdiri dari primer dan sekunder kalau dari primer
Kerusakan fisik Mampu merusak berbagai jenis struktur, termasuk jembatan, mobil, bangunan, sistem selokan bawah tanah, jalan raya, dankanal. Sedangkan Sekunder
Seperti Air minum bersih mulai langka.Penyebaran penyakit bawaan Kelangkaan hasil tani disebabkan oleh kegagalan panen. Spesies yang tidak sanggup akan mati karena tidak bisa bernapas.Jalur transportasi rusak

Cara penanggulangan banjir berupa
·Membuang lubang-lubang serapan air,memperbanyak ruang terbuka hijau, mengubah perilaku masyarakat agar tidak lagi menjadikan sungai sebagai tempat sampah raksasa

Dari berbagai dampak negatif yang ditimbulkan, ternyata banjir (banjir air skala kecil) juga dapat membawa banyak keuntungan, seperti mengisi kembali air tanah, menyuburkan serta memberikan nutrisi kepada tanah.

The flood is the event that occurs when the excessive flow of water soaking the land. The flood caused by the volume of water in a body of water such as a river or Lake that overflowed or bust the dam so that the water coming out of its natural limits. Flooding can also occur in rivers, when the flow exceeds the capacity of the drains, especially in the bend of the river. The cause of the occurrence of floods can be natural or the result of a human hand, if from natural river Sediment is usually because of rain or melting snow quickly exceed the capacity of the river channel. While from a human hand Damage caused by human activity, whether deliberate or not damage the natural balanceThe impact brought about by flooding consists of primary and secondary if the primary Physical damage is capable of damaging the various types of structures, including bridges, cars, buildings, sewer systems, roadways, dankanal. Whereas SecondarySuch as clean drinking water a rare start. The spread of the disease is congenital scarcity of produce is caused by crop failures. Species that are not able to be dead because could not breathe. Damaged transportationHow to flood relief in the form of · Discard the water absorption pits, reproduce the Green open space, change the behavior of people to no longer make the River as a giant trash canFrom a variety of negative impacts posed, turned out to be flooded (flooded water of small scale) can also bring a lot of benefits, such as replenish ground water, fertilize and provide nutrients to the soil.
