Floods of 1998 in Bangladesh and Shrewsbury
Causes, Effects and responses to flooding In Shrewsbury
The Severn Valley floods, Shrewsbury, UK 1998:
Causes
======
The human causes of the floods were summed up by the then Shadow
Countryside Minister Tim Yeo MP, he said 'the flooding had increased
because of the housing developments on Greenfield sites.' By this he
means that by covering the land with tarmac in urban areas humans have
increased the rate of surface runoff and decreased the saturation
levels of the ground. When surface runoff is high rainwater reaches
the river faster. It would appear that the speed in which the water
reached the river was too fast for the river to handle. The river
filled up reaching bank-full discharge and then overflowing its banks
onto the flood plain. The flood plain of the River Severn is built on,
therefore, when the river floods it floods onto residential areas.
With the building of these urban areas the amount of vegetation in the
area surrounding the river was reduced, this affects the river two
ways. It reduces the amount of interception, which in turn increases
the speed of runoff into the river. The lack of vegetation also leads
to the saturation of the ground. During the months of October and
November the rainfall in the Severn Valley was high, as the water
soaked into the ground it became saturated. More vegetation in the
area would have meant the vegetation using the water would have
decreased the amount of water in ground storage.
Physical factors of the flood in 1998 are many; however, the most
important one was the amount of rainfall. In October 1998 many areas
received record amounts of rainfall caused by a 'hurricane'. This
'hurricane' brought very heavy rain and strong winds. The fact the
rain was heavy means that the river did not have time to dissipate the
water quick enough and the runoff was too fast, making the river rise
t such an extent that it flooded.
A flood is a large amount of water that covers an area that is normally dry. Floods can occur almost anywhere, but they happen more often on floodplains and on places close to the ocean. The land that floods regularly is called a floodplain. It is called coastal flooding when a large storm or wave from the ocean causes flooding in the cities inland. Some floods take days to develop, while others take minutes to form these are called flash floods.
A major flood on any river is both a long-term and a short-term event, particularly any river basin where human influence has exerted "control" over the ri...
Few disasters in history were able to be as easily prevented and had such a large causality figures as the Johnstone Flood which occurred in 1889. In is an incident that few people know about but has had a significant impact on how we look at preparedness and mitigation in the Emergency Management field.
The Johnstown Flood Stained the history of the United States. Over 2000 victims died and even more injured. The flood has been blamed on many people since it happened. One group individually brought about the flood. The South Fork Fishing and Hunting Club made selfish changes threatening the effectiveness toward holding back a water overflow. The renovation made to the dam brought about the destruction killing many people and causing millions of dollars in damages.
When it floods sediments can affect the land by losing nutrients in the soil and it can also affect the clarity of
The Johnstown Flood killed over 20,000 innocent people lost their lives because of the terrifying flood. The flood was one of the deadliest floods in Johnstown. Poor Johnstown got whipped out from the tremendous flood. This flood came roaring down from the dam that had broke down. The poor dam couldn't hold all the water so it broke down.
One obvious reason that this hurricane was so devastating was due to weather patterns. Harvey was originally just a tropical storm, but jumped from a category
Imagine a family sitting at home watching a calm game of baseball, when suddenly they realize that a massive wall of water is approaching the neighborhood. Where did this flash flood come from, a reader might ask? The wall of water was made by the raging winds and immense power of Hurricane Andrew. Hurricane Andrew was the second most expensive storm in history that destroyed over 250,000 homes in the states of Florida and Louisiana alone. Hurricane Andrew was not predicted to make landfall, so when it did many civilians did not have any idea that the Hurricane was coming until it was almost too late.
One issue facing my locality is constant, yearly flooding that disrupts much of Glenville and the entire county. The Mayor of Glenville, Dennis Fitzpatrick, mentioned in an interview with me that “almost every year major flooding occurs,” and as someone who has lived near Glenville my entire life, I have also noticed the major issue of flooding as well. In Glenville, almost every ten years there is a major flood event that disrupts businesses and schools, while leaving much of the town with a mess to clean up afterwards. This is a pricey burden for a small town, and one that puts more and more local business at the risk of closing permanently. Once, my grandmother had
Moreover, Rainsford wouldn’t need to worry about anything because he can outsmart them. He most likely felt accomplished because of the trail he retraced. He did a “series of intricate loops” he retraced them over and over “recalling all the lore of the fox hunt and all the doges of the foxes” (Connell 32). He did this due to the fact in which he thought retracing the path will cause Zaroff to get confused and lost. This shows he's creative. Meanwhile around the same time, he was being careful. In this case, he was “at a big tree with a [wide] trunk and outspread branches was nearby, and [being careful] not to leave any marks” (Connell 32). Once again he was trying to outsmart the cays to where they wouldn’t sense him so he climbed up the
The Sumero-Babylonian version of the epic of Gilgamesh, after two and a half millennia of dormancy, was resurrected by British archaeologists in the nineteenth century. Amid the rubble of an Assyrian palace, the twelve clay tablets inscribed the adventures of the first hero of world literature – King Gilgamesh, whose oral folk tales go back to at least 3000 years before Christ (Harris 1). Tablet XI contains the story of the Flood. In this essay let us compare this flood account to the more recent Noah’s Flood account in Genesis of the Old Testament.
McCullough presents a meticulously researched, detailed account of the Johnstown Flood of May 31st 1889, which provides arguments for why the disaster was both “the work of man” and “a visitation of providence”. However, it is apparent that McCullough believes that man was more responsible than nature/god for the extent of the catastrophe. In McCullough’s opinion, the storm that caused the flood was no more than the inevitable stimulus of the disaster, whereas the deferred maintenance and poor repairs on the dam were the primary reason that Johnstown was devastated in 1889. McCullough exposes the failed duties of Benjamin Ruff and other members of the South Fork Fishing and Hunting Club, whilst simultaneously questioning the responsibility of the Johnstown folk who were concerned about the safety of the dam but complacently trusted the wealthy, powerful club members to fulfil their responsibilities. McCullough clearly explains the debate that took place immediately after the flood, on what or whom was to blame for the disaster, by explaining the views of the press, the townspeople and the lawsuits that were filed. McCullough’s view is evident from the sub-title of his book. By placing the word “natural” within quotation marks, McCullough immediately suggests that the flood was unusual to any other, and implies that mankind has displaced its blame onto nature.
If the gradient is steep (like the example on the right) then this can indicate that the amount of rainfall becoming overland flow is very high, the result of this is that all the water reaches the river very quickly and all in a short period of time, this gives the immediate steep ascending limb on the hydrograph. Reasons for large amounts of rainfall becoming overland flow can be little vegetation and maybe impermeable rock below the surface. Being impermeable rock, the water cannot infiltrate through this and become ground water, instead it flows over the ground to the river. Urban development and agricultural practices contribute to overland flow.
Did the Great flood really happen? Was it all just a big made up story? Or did the Bible speak the truth. Evidence from all around the world has pointed to the fact that the flood happened. The city of Ur was destroyed by a flood. All the different stories in the world of the flood save one family. Abraham could have carried the story of the flood of Ur. The theories of the flood do not contradict the Bible. Also the Black Sea wasn’t always a body of water. Although the Great Flood was thought to be a myth, scientists may have found evidence the flood existed because scientists may have found the boat, they have found houses underneath the Black Sea, and many cultures have variations of the flood.
Flooding in Bangladesh Bangladesh is a low lying country and almost all of Bangladesh lies on the largest delta in the world. It is situated between the Himalayas and the Indian Ocean with a vast river basin made up of the Ganges, the Brahamaputra, the Meghna and their tributaries. It also has the highest population density in the world with 847 inhabitants per square kilometer. Bangladesh is one of the world's least developed countries and prone to natural disasters, such as cyclones, floods and droughts. Half of it is less than five meters above sea level.
