1 Introduction
Flooding becomes a major issue for all parts of the world. This causes due to heavy fall of rain water and sudden change of whether conditions. Due to lack of the capacity of existing cannels and irrigation systems, water flow becomes slow and dry lands fill up with water. This result the phenomena. This may happen naturally or sometimes due to man made changes to the natural landscapes. When consider about natural causes for flooding, it varies according to various parts of the world, such as spring thaw, Ice jams, heavy rain (monsoon), snowmelt, winter rainy season, tsunami and also sometimes due to rains fall after a wildfire. Apart from these natural conditions, human activities also cause flooding conditions. Blasting, this causes landslide which may block rivers and streams. Sudden failure of structures such as dikes, dams, etc… which was build to store large capacity of water. Because of unintentional damages or sudden failures of structures, large amount of water may release to dry lands. Failure to manage such streams of water will leads to flooding condition. However it causes, it is a major disaster which devastates human life and economy. Failure to manage such situation properly, will leads to major health issues also. So far thousands of peoples were fall in to death toll due to this massive disaster.
1.1 Effects of floods
In July 2013, more than 5,700 peoples were fall in to death list due to flood, affected to northern part of India. Indian troops were able to evacuate more than 110,000 peoples form effected that area. Environmental experts elaborated about the scene, that catastrophic were immerged due to imbalance of the ecological system. This happened...

...rce to birth such events. Due to urbanization, deforestation are some examples. When consider about world whether, the rain fall and melt of ice burgs is increasing due to global warming. When analyze local and global information about flooding, it can seems number of events are gradually increasing. Apart from proper urbanization and darning systems, it is necessary to monitor vulnerable areas and existing irrigations channels about sudden changes of water levels. Even though people have developed good systems to monitor and alert about variations of water levels, due to economical status of most governments who suffering each year from flood, cannot afford such systems. In this project, it is concerned to facilitate a proper warning/alerting system which is capable of to identify changes of water levels at given point, while keeping implementing cost is minimal.
Case study: the flooding that occurred in Minden Hills in the spring of 2013, flooded the downtown core. The picturesque cottage town has the Gull River flowing through it. The river overflowed in April because of many reasons: a couple of days of rain, the third largest amount in over a century, but it also happened because the frost in the ground stopped the water from going into the Earth, the lakes and rivers being full from the spring thaw, and the rapid

Though scientists cannot agree on whether or not a global flood occurred, the effect of these stories on science has been monumental, as well as the effect of the stories on cultures and religions throughout the world. If this great flood did , in fact, occur, it’s effect on history would have been great because of the huge numbers of people lost to it. Though they may be fables, one must keep asking themselves if they may have been based on fact.
Louisiana has problems with flooding. The Mississippi River borders the East Side of the state and often floods due to precipitation. Other for reasons flooding includes dam failure or land problems. The flooding has a major affect on the people in the state since they must . deal with the water and all of its damage. The scope of the problem is precipitation. Hurricanes can hit Louisiana and cause flooding in the lower Mississippi. Also heavy rains often hit the state. “A slow moving weather system dropped large amounts of rain over northern Louisiana…”(FEMA, Feb 1, 99). The amount of time in which rain falls is an uncontrollable factor causing the state tobe well prepared for all types of flooding. Dams are a good way to help the flooding. Flooding is an earth science related problem in Louisiana.
Craig E.Colten’s book centers on a familiar problem that New Orleans city constantly faces, the flooding. In particular, the book focuses on the genesis of the flooding danger. In reference to Colten’s book, this essay will attack the statement “The environmental elements, as opposed to human actions, fully account for New Orleans’ problem with water”. The rationale of opening up unusable land by draining waters and construction of levees to contain Mississippi River water led to serious flooding during heavy downpour. After raising the levee systems to the desired levels in 1920s, the issues of drainage become apparent and the heavy rainfalls became the main cause of the wave of flooding in New Orleans. The thunderstorms –spawned rain replaced Mississippi River as the greatest threat. The water problem in New Orleans emanated from the human behavior of destroying natural conditions in New Orleans through natural environment modification to accommodate residential and commercial housing. From the foundation, New Orleans faced flooding threat, first from the Mississippi River and then downpour floods. Colten (2005) maintain that human wrested New Orleans site from nature resulting in continual struggle with water and floods.

Due to the majority of Niger being hot, dry, and dusty desert, extreme natural disasters such as droughts and floods have become prone to Niger’s landscape, leading to a number of widespread problems. According to “Internationally Reported Losses 1990 – 2014 EMDAT” from the International Disaster Database, 73.1% of Niger’s total annual average losses were caused extreme floods, 23.1% droughts, and 3.8% storms. The database also reports 98.6% of deaths being caused by floods, and up to 100% of major economic issues being directly caused by extreme floods. Outbreaks of epidemics and the spread of disease throughout Niger’s living environments have also had a major impact on Niger’s increasing food crisis. Niger’s large number of natural disasters has resulted in poor, decimated or failed harvests, food shortages, reduced number of workers and destruction of farmland has ultimately resulted in food scarcity and higher prices for the available
In 1970, East Pakistan, about the size of Wisconsin, had a substantial population of 66 million, meaning that each square kilometer holds about 400 people (Disaster 174). It is located precisely where two large river systems, the Ganges and the Brahmaputra, unite to form the biggest delta in the world, the Ganges River Delta. A delta is a triangular deposit of sediment at the mouth of a river, naturally where it diverges. The two rivers conduct silt from as far as the Himalayas to the floodplains of Bangladesh, which are about 1,200 miles apart. Being one of the world’s most fertile croplands, the floodplain is densely populated. Farmers are forced to move farther and farther out into the delta, triggering them to face the perilous monsoon season, which is from June to October. One third of East Pakistan is no more than twenty feet above sea level, maximizing the death toll of life-threatening storms (History 3). The a...
Flooding has always been part of the natural environment of Thailand. Since historical times populations that live within the urban and rural floodplains have learned of ways to adapt and survive (Balancing 2). With the economic development of many areas within the floodplain regions over the later part of the last century many areas have become further susceptible to seasonal rains and flooding.
“For most of the history of our species we were helpless to understand how nature works. We took every storm, drought, illness and comet personally. We created myths and spirits in an attempt to explain the patterns of nature (Druyan).” According to Fox, Drought came also be seen as a slow- motion train wreck. We still have a very short time to get the people off safely before the crash. This drought is causing long dry period in regions were rain fall is usually frequent enough. From there this drought is turning to more like a famine because the area in drought is so huge and is causing much conflict for the survival of the people (2011). These areas include Somalia, southern Ethiopia, and northern Kenya.
People in Bangladesh aren’t educated enough to build any appropriate flood protection and to maintain them. The problem concerning Bangladesh is that most of the land is only a few feed above water and very unstable. No amount of river control can change this. To alleviate the impact of flooding Bangladesh’s only choice has to be severe population controls to reduce the density of people on this land and also to encourage a movement away from the lowest lying areas. It is also believed that Bangladesh will each year run a three-times higher risk of suffering an exceptionally wet monsoon compared with the probability today, thus it is also expected that parts of Bangladesh face the risk of more frequent, major floods in the latter half of this century because of global warming.

The least violent type of natural disasters is the flood; it is one of the most frequent hazards. A flood can affect local areas or a very large area affecting entire river deltas. Not all foods are alike, some of them develop slowly over a period days and some of them occur in a matter of minutes. The floods that develop quickly are known as flash floods; flash floods have a dangerous wall of thunderous water that carries rocks, mud and other different debris. If you live in a low-lying area near water you more prone to flooding, the smallest streams, gullies, creeks, and streambeds can cause a flood. Floods are often not a common thought when you think of a natural disaster, but they can be fatal, destroy homes, businesses, and roads, happen when you least expect, and happen when you are not prepared (FEMA:Flood). An extreme example of this type of natural disaster is the flood in eastern Australia last month; the flood, which lasted for weeks, caused thirty dea...
Water is an integral part of not only human beings but all other creatures in the world. We use it every day for different purposes such as domestic, agricultural and industrial. Water has always been a prestigious resource. However, the majority of people do not appraise water’s worth since they do not face water scarcity; whereas, in third world countries it is one of the most serious problems. Nearly 2.4 billion people have a lack of water resources in the world, shows the investigation done by the Pacific Institute, an Oakland, California-based non-profit scientific research group. Moreover, every year this number is growing gradually and more people are suffering (Bloomberg News, 2010). There are certain causes which deteriorate current situation. The most influential reasons are global warming, pollution by human-beings and overpopulation. It is known that India is one of the countries which face water scarcity so this essay will consider the possible ways of solutions of water shortage in India.
