1.0 FLASH FLOOD AS AN URBAN ENVIRONMENTAL ISSUE
Malaysia had experienced an urbanization process from many years ago. While urbanization plays part as an asset to development of a country, there are price which we need to pay. One of it being the exposure to the risk of urban environmental problems. Environmental problem is defined as an environmental burden that arise because of urban activities. It means that, environmental problem is an event that cause burden to the environment which its occurrence was the result of urban activities. With this regard, flash flood was considered as an environmental problem because it can harms urban environment Basic environmental impacts of flash flood are changes of structure along the river course and erosion and deposition of mud at river banks and roads. Besides that, it also caused low level household wastes to be dispersed into rivers and resulted in contamination of water supplies for the community living in urban area. During flood, toxic and rubbish will enter into rivers and therefore may harm the aquatic life as well as the cleanliness of the river. Therefore, this event might lead to other urban problem which are shortage of clean and safe water supply. 2.0 FLASH FLOOD CAUSES
2.1 CLOGGED DRAINS The problem of clogging drains are the responsibility of city’s occupants, squatters as well as house developers. First of all, city’s occupants, especially squatters are responsible for load of rubbish thrown in drains and
As per that subsequent disaster, floods can now be prevented by forming a management committee set to prevent that from happenings in every county, they say prevention is better than cure and so the government is coming up with measures to control floods. This is done by sensitizing people who live on lower grounds to move to higher grounds to prevent landslides, digging dykes and also educating citizens on disaster
Introduction The definition of natural disasters is any catastrophic event that is caused by nature or the natural processes of the earth. The severity of a disaster is measured in lives lost, economic loss, and the ability of the population to rebuild. All natural disasters cause loss in some way. Fields saturated in salt water after tsunamis take years to grow crops again.
Flooding Disaster Flooding - arrive in overwhelming amounts or quantities or large amounts of water. We are going to talk about how flooding destroy people 's lives and homes around the world. One of the country’s worst flooding disasters occurred February 26, 1972, on Buffalo Creek in Logan County in West Virginia. It was about 8.00a.m a coil waste dam collapsed on the Middle Fork of Buffalo Creek releasing 132 millions gallons of water into the city and destroying everything. Next were are going to talk about another bad flood that is the Mississippi river flood of 1927, on September 1 water poured over a dozen streams and flooded towns of Carroll, Iowa to Peoria and Illinois three hundred miles and fifty miles apart.
Water is a critical source used all around the world to keep our way of life flowing. The use of water goes from regular house needs to creating energy in many ways. Around the world drinkable water starting to run low and the water stored is being contaminated by pollutants causing sickness and death. Countries are going through droughts which affects the water supply needed to maintain irrigation, and public supply. Water pollution is defined as the presence in groundwater of toxic chemicals and biological agents that exceed what is naturally found in the water and may pose a threat to human health and/or the environment.
Rain is a natural occurrence and in Miami County, Ohio the average precipitation rate is approximately 38 inches a year. The average yearly rain fall across the United States is 36.5 inches yearly; they are close in comparison (Sperling’s Best Places, 2015). However, if rain comes down quickly or in large quantities a flood can occur.
Meanwhile, the methods of waste disposal have improved over time. Also, that getting rid of garbage is quickly becoming a big problem due to our methods of waste disposal are only a temporary solution. Moreover; the waste that can’t decompose
Flash floods may cause loss of lives and properties. Soil erosion will leads to loss of minerals for the land. The land cannot be used for
A generic definition for flood is something like this: It is an overflow of a quite large amount of water that goes beyond the normal level at a given area which is normally considered a dry land. But this simple definition hardly captures the picture of the disaster a flood can become and the damage it can wreak on a locality. With rapidly increasing unpredictability of the weather patterns globally and a number of natural and man-made factors interfering with the environment, a flood is a more common scenario today than ever. It is now considered as the most costly natural disaster too, as the recurring damages done by the floods across the country is putting a heavy toll on the financial planning and estimations nationally.
Megacities are populated with Millions of residents, a city that is overcrowded causes issues with adequate water supply in many cities. Shanghai, China and Karachi, Pakistan have a scarce water supply; some residents go days or weeks without water because of contamination and high prices. “Around 300 million people are suffering from water shortages.” Deaths have arisen due to water contamination, killing thousands of people yearly. Karachi water is be stolen and sold on a daily basis; making low income families paying extremely high prices to get the essential water that is needed.
They also include the replacement of undersized structures such as bridges. These works are necessary, as the original channels have become undersized as a result of the increase in flood flows caused by development. Flash flood also can be overcome with storage ponds of flood attenuation. Ponds such as disused mining pools can be used for flood storage. The objective is to divert the flood water through such ponds and thus regulate the outflow so that the flood peaks are attenuated.
2.8 Main Cause of Flood According to Jabatan Penerangan Malaysia (2012), issues of flood that happen certainly had their own causes. There are many causes such as: 2.8.1 Continuous Rain Continuous rain without stopping can cause flooding. In low areas, rain water will flow into the river. River filled with water will overflow causing lowland area are flooded.
CHAPTER 1 1. INTRODUCTION The air we respire contains mixture of natural and man-made chemical, physical and biological elements that modifies ambient air quality. Among all air pollutants, the most threatening for human health include particulate matter and gaseous pollutants such as carbon monoxide, ozone, nitrogen dioxide and sulfur dioxide (WHO). The movement of people into urban areas and the growth of industry within these areas has carried more people into contact with air pollution than any other time in recent memory.
One of the greatest issues that we face towards the environment has been an increasingly difficult problem over the last few years. Earths climate is changing at rapid paces and solutions are needed as quickly as possible to replenish natural ecosystems and cultures that depend on the environment. Climate change not only affects the animals in our ecosystem, but us humans as well. With the human population increasing every year, climate change is only getting worse. Many argue that the effects of climate change towards the environment are due to other extraneous factors, however, I myself am a strong believer that the problems such as rising sea levels, warmer temperatures and natural disasters are all due to both natural causes and human activity.
Industrial and capital hubs in developing countries are similarly characterized by multiple urban sprawls, informal settlements and overcrowding. The local governments or municipalities in many developing countries are highly challenged by mainly poor or weak policy and legislative provisions to regulate and enforce waste management guidelines. They also lack adequate funding and the correct capacity in terms of waste management personnel. All these challenges lead to situations where these local authorities are failing to take effective decisions with regards to solid waste management. It is worth noting that the decisions which municipalities are facing in terms of managing solid waste are not only difficult and capital intensive but they impact greatly on the natural environment as well as on social lives of people, therefore solutions to this issue are a matter of
THE IMPACT OF TECHNOLOGICAL ADVANCES ON THE ENVIRONMENT AND HUMAN HEALTH Technology is a major part of everyone’s life. Technological advances are encountered at home, school and at work. These technological advances have become so helpful to people lives. Every year new technologies appear to help people to live more comfortable by allowing them to do more with less effort. That’s why expressions such as “I do not know what I would do without the washing machine” or “I could not live without my cell phone” are heard more frequently.
