Flood is one of the most dangerous natural disasters. It happens when excessive water is collected in any area. It usually happens due to heavy rainfall. India is highly prone to flood. There are many regions in the country that face this natural disaster because of the overflowing of rivers. Moreover, it also happens because of the melting of snow. Another reason for floods is when the dam breaks down. If we look at the coastal areas, the hurricanes and tsunamis are held responsible for causing floods. In this essay on flood, we will see the prevention and after-affect of flood.
In other words, whatever the cause may be, it is equally dangerous. It has a lot of harmful consequences. Flood damages the living conditions and it takes a lot of time to recover from this disaster. Therefore, the consequences of floods must be known and steps must be taken to prevent it

Riverbank Erosion an endemic and recurrent natural hazard in Bangladesh. When rivers enter the mature stage (as in the case with the three mighty rivers, ganges, brahmaputra and meghna) they become sluggish and meander or braid. These oscillations cause massive riverbank erosion. Every year, millions of people are affected by erosion that destroys standing crops, farmland and homestead land. It is estimated that about 5% of the total floodplain of Bangladesh is directly affected by erosion. Some researchers have reported that bank erosion is taking place in about 94 out of 489 upazilas of the country. A few other researchers have identified 56 upazilas with incidence of erosion. At present, bank erosion and flood hazards in nearly 100 upazilas have become almost a regular feature. Of these, 35 are severely affected.
Some rivers cause erosion in large scale and high frequency due to their unstable character.
