Effects of floods

The additional cost of rehabilitation, relocation of people and removal of property from flood-affected areas can divert the capital Effects of floods for maintaining production. The main channel slope is the second most important factor for larger watersheds.

The stress of overcoming these losses can be overwhelming and produce lasting psychological impacts. Deluge myths are mythical stories of a great flood sent by a deity or deities to destroy civilization as an act of divine retributionand they are featured in the mythology of many cultures.

According to the U. Floods can also contaminate drinking water and lead to diseases. Floods destroy drainage systems in cities, causing raw sewage to spill out into bodies of water.

Without any observed rainfall, the flow rate increased from about 50 to 1, cubic feet per second 1. Floods cause significant amounts of erosion to coasts, leading tomore frequent flooding if not repaired.

Effects of floods increase in flow may be the result of sustained rainfall, rapid snow melt, monsoonsor tropical cyclones. If Effects of floods area is prone to floods, houses in the region should be constructed on raised platforms.

The benefits of natural floods almost certainly outweigh the negative aspects. Rainfall intensity is the second most important factor for watersheds of less than approximately 30 square miles or 80 square kilometres. Floods are not always destructive natural events. Rapid flooding events, including flash floodsmore often occur on smaller rivers, rivers with steep valleys, rivers that flow for much of their length over impermeable terrain, or normally-dry channels.

Hurricane Katrina caused a massive flooding of the whole Mississippi Delta in Floods cause tremendous destruction of life and property. However, on March 12,the dam broke, unleashing a 78 foot wall of water.

Coincidence Extreme flood events often result from coincidence such as unusually intense, warm rainfall melting heavy snow pack, producing channel obstructions from floating ice, and releasing small impoundments like beaver dams. Conversely, given the observed inundation area of a recent flood and the channel conditions, a model can calculate the flow rate.

Many more are injured and others made homeless. For example, farmers can remove animals from low-lying areas and utility services can put in place emergency provisions to re-route services if needed.

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 percent for warm rain on accumulated snow.

Before the Assuan High Dam was built yearly floods in Egypt brought along nutrients and made the land around the Nile very fertile. The time of concentration defines the critical duration of peak rainfall for the area of interest. In addition to this, flooding brings a lot of diseases and infections including military fever, pneumonic plague, dermatopathia and dysentery.

Areal flooding begins in flat areas like floodplains and in local depressions not connected to a stream channel, because the velocity of overland flow depends on the surface slope. Heavy rains, landslides, overflowing rivers, cyclones and tsunamis cause floods in India.

The impact on those affected may cause psychological damage to those affected, in particular where deaths, serious injuries and loss of property occur.

Today a series of dikes and dams protect the land behind the coast.

Flood waters provide much needed water resources in arid and semi-arid regions where precipitation can be very unevenly distributed throughout the year and kills pests in the farming land.

Floodwaters carry lots of nutrients that are deposited in the plains. They cause decay of organic matter, leading to growth of infection-spreading germs.

Authorities in Japan fear that Fukushima radiation levels are 18 times higher than even thought. Water supplies, crops and food supplies, and even.

After earthquakes on the ocean floor tsunamis can bring up to metre high waves and flood the coast many miles inland.

Channel slope and rainfall intensity become the third most important factors for small and large watersheds, respectively. The damage to property houses, schools, factories, roads is called material damage.

This canlead to catastrophic effects on the environment as many toxicmaterials such as paint, pesticide and gasoline can be releasedinto the rivers, lakes, bays, and ocean, killing maritime life.EFFECTS OF FLOODS Floods are mostly caused by the intensive rainfall that incereases the water level dramatically and results excessive water overflow that might have some devastating effects on te endangerd areas.
