The cause of the flooding is attributed to high tide, low atmospheric pressure, and wind patterns. And when these three things combine at the right levels, it can result in 90% of Venice going under 140cm underwater. As recently as November 12, 2012, there has been an article published by The Australian reporting that 70% of Venice is currently underwater. Major tourist attractions such as the Piazza San Marco, or St. Mark’s Square, are under at least a foot of water. This causes a lot of trouble for the tourists who are visiting, and also discourages other tourists to follow through with their travel plans and make their way to the flooded city.
Measures to manage the problem were efficiently introduced by the government, though much losses could be observed, including death of 9 people and high level of pollution in nearby areas. Natural hazard events in most cases cannot be predicted. Although some speculation of flood or drought may appear when precipitation anomalies occur and river water-levels vary, as well as earthquake may be preceded by anomalies in earth’s magnetic field, even with the use of technology it is impossible to predict those distasters. Many of them, similarly to human induced hazards, occur unexpectedly and cause long term damages, as it was in case of Haiti earthquake in 2010, however the scale is much
What are the Main Environmental issues of Sydney Harbor? Of the threats facing Sydney Harbor none is worse than pollution. Sydney's waterways faced decades of dumped toxic waste before regulations in the 1970s banned the practice. More issues concerning the Sydney Harbor are deforestation and traffic of vehicles. Also storm water management needs to be improved.
Louisiana does not specifically fit into every one of Diamond’s five-point structure, but we can evaluate Louisiana with most of them. Choosing to build levees once seemed like a good idea. The benefit of the levees would out way the costs. This is not true though. Everyday the environment is damaged because of these levees.
Question 1 a) Pollution in the nile rises so this halts the drinking water being released from the water stations this is because it doesn't meet the drinking water standards, caused by the niles low water level. Egyptian villages are protesting against the government for not doing anything about the problem, and this could lead to huge environmental disasters. Mass poisoning has occurred in various areas because of this, the government are being sued for the contamination of water. The government has three reasons for this which are low water levels, presence of fish farms and villages disposing their waste into the river. word count= 100 b) This is an MCD(multiple cause diagram) showing the factors that contribute to water pollution in the lower nile.
As a result, earthquakes can and do occur, notably on Luzon Island in 1990. It measured 7.8 on the Richter Scale and killed over 1500 people. A reason for this major difference in death rate compared to California is that the Philippines is poorer than California and so cannot afford as much earthquake-proof buildings and the buildings are of poor quality. This may mean the buildings can collapse easily and so can kill people easily. A natural hazard that does not affect California but common in the Philippines are tropical storms.
It is this side-to-side load which causes the worst damage, often collapsing poor buildings on the first shake. The side-to-side load can be worse if the shocks come in waves, and some bigger buildings can vibrate like a huge tuning fork, each new sway bigger than the last, until failure. This series of waves is more likely to happen where the building is built on deep soft ground, like Mexico City. A taller or shorter building nearby may not oscillate much at the same frequency. Often more weight has been added to a building or structure at most frequently at greater heights; say another floor and another over that; walls built round open balconies and inside partitions to make more, smaller, rooms; rocks piled on roofs to stop them blowing away; storage inside.
Becoming a forensic photographer is not an easy job, you have to remain empathetic and calm while taking pictures of traumatic and disturbing scenes, it takes a person of strong will and someone that can control their emotions. One of the most controversial cases was the cause of the Tay Bridge disaster of 1879, when half of the bridge collapsed in a storm while taking a train into the estuary of the Tay river. In 1999-2000, when photographs were digitized to show critical details forensics were able to find the reason why the bridge fell apart. They were able to find that the weak structural beams and strong winds were able to weaken the
On the positive side the dam is a renewable energy source but environmentally speaking it has done more damage than good. The construction of the TGD has had a huge negative impact on the environment all along the river. The controlled water flow has caused a decrease in water quality and changed the niche of many wild life species. Fish can’t simply swim up and downstream freely anymore which can affect their diet and matting patterns. The water behind the reservoir has destabilized some of the steep hills on the edges of the water causing landslides that can be very dangerous.
They are born from tropic waters that affect quite a few across the world but in the Gulf of Mexico they tend to wreak particular havoc. These storms have potential for mass devastation through storm surges that flood the coastline often taking lives and possible contamination of water supplies, heavy rain which contributes to flooding situations and high winds coupling with tornadoes that destroy property, Storm surges are among one of the worst factors of a hurricane. Often, at the time, people do not even realize the impacts a storm surge can have and do not head authorities warnings to evacuate the coastline, which can result in a high death toll. As Jay Barnes notes in his research: As a hurricane churns across the open sea, the combined effects of the storm’s lowered barometric pressure and strong, inward-spiraling winds create a deep, swirling column of water beneath the ocean’s surface. This effect causes the sea level to rise in the vicinity of the storm, creating a dome of water that may be a few feet high in the center and a hundred miles wide.
