Bangladesh Flood

causes and effects of flood in points

When the stress tends to be more than what the rocks of the earth can bear, the rocks are broken and displaced from their state of equilibrium. 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, or it may occur due to an accumulation of rainwater on saturated ground in an areal flood. This is because flooding can carry bridges, cars, houses, and even people. The main difference between floods and flash floods is the size - flash floods are small and short-term. The final limitation in coastal flooding lands is often the or some coastal flooding bars which form natural. Flooding has always been a part human history.

Effects of Drought The effects of drought are widespread and have devastating effects on the environment and the society as a whole. Because of all this the economic growth has not and will not grow as much as it would otherwise have done if the floods never occurred. Their average width ranges from 50 to 300 miles long. Finally dam failure can be the producer of a flood. Culverted fills may be converted to impoundments if the become blocked by debris, and flow may be diverted along streets. Additionally, floods can be local, impacting a neighborhood or community, or very large, affecting entire river basins. When overland flow occurs on tilled fields, it can result in a where are and carried as suspended matter or.

Direct consequences happen at the time of the floods. Fish are easily poisoned with metals that are also later consumed by humans. Deforestation In poor countries rapid deforetation has taken place. This coincided with the normal floods and made the severity much worse Climate change Global warming has been blamed fr what some claim is an increasing frequency of flooding. The outcome of a flood can be catastrophic.

This is what happened to the Mississippi River in 1927, when the river flooded 27,000 square miles of land about the size of Connecticut, Massachusetts, New Hampshire and Vermont combined and put much of that land under 30 feet of water. Rivers that flow slowly carry water, sand and silt. One cause of a flood is when water exceeds the capacity of the area it is in; thus causing it to overflow outside the waters boundary. Short duration precipitation is more significant to flooding within small drainage basins. These dense groups of storms spin slowly anticlockwise.

The waves then crash onto the beach and flood the flat land by the coast. Heavy Rainfall: Causes increase in sea level rise etc. Every year floods during the season in Bangladesh deposit fertile soil but also kill thousands of people and leave millions homeless. Conversely, if a basin is sparsely vegetated then there will be no interception and so more water will enter a river. The fraction of incident precipitation promptly reaching a drainage channel has been observed from nil for light rain on dry, level ground to as high as 170 percent for warm rain on accumulated snow. Less predictable events like tsunamis and storm surges may also cause elevation changes in large bodies of water.

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 floodproperty or drown domestic animals. In this sense, deforestation — clearing vegetation cover and cutting down trees increases evaporation and lessens the ability of the soil to hold water leading to increased susceptibility of desertification. Deforestation: With fewer trees to absorb or slow down rainfall through the leaves and soil , the rainwater travels at a faster speed towards the rivers, then increasing water levels etc. The flood flow in urbanized areas constitutes a hazard to both the population and infrastructure. Recent field measurements during the showed that any criterion solely based upon the flow velocity, water depth or specific momentum cannot account for the hazards caused by velocity and water depth fluctuations.

A natural disaster can cause loss of life or property damage, and typically leaves some economic damage in its wake, the severity of which depends on the affected population's resilience, or ability to recover. Massive dams that hold water back prevent flooding. The whole storm spins around the eye. Flooding may occur as an overflow of water from water bodies, such as a , , or ocean, in which the water overtops or breaks , resulting in some of that water escaping its usual boundaries, or it may occur due to an accumulation of rainwater on saturated ground in an areal flood. Among many other , some regions are now experiencing increased precipitation and flooding.

The Bangladesh government gave out free seeds to the farmers, who were hit hard by the flooding, after loosing all their crops and cattle. Floods often cause damage to homes and businesses if they are in the natural flood plains of rivers. The Bangladesh flood had had countless detrimental effects on the country but contrastingly, it has also brought together international help with the disaster. Agricultural lands are destroyed due to crops being submerged in water. Indirect Loss of industrial production, traffic disruption, loss of customers.

It is predicted that globalk warming will result in reduced rainfall in some areas, but in other, such as western Europem rainfall totals might increase. When the snow does melt, large volumes of meltwater will enter the river increasing its discharge and triggering floods. Water use is part and parcel of almost every human activity as well as the life of plants and animals. Individual data points are converted to intensity by dividing each measured depth by the period of time between observations. Like a large pile of water moving across the ocean with the hurricane, storm surges build up and engulf coastlines - devouring buildings, vegetation and anything else present. People can be trapped at home because the water is so high that you cannot go out. They can destroy homes and other infrastructure, and can lead to a loss of crops, to , and to a loss of human life.

As a consequence, this creates a sudden discharge of water into the adjacent lands leading to flooding. A , from either a or an , falls within this category. Floods are a powerful force on our planet. If conditions remain the same, which means there is enough fuel for the storm to continue developing, the rotating storm will continue to get powerful, eventually becoming a hurricane. However, as you know, floods are also dangerous and can destroy homes and livelihoods as well.
