Download file to see previous pages The flood defenses were strong barriers that prevented water from flooding into the plain land (Woods & Woods 2007, p.5). Floods occur when flowing surface water spills over the confining banks into the dry land. Floods are a natural phenomenon, which occur in almost all river systems. Areas prone to flooding include those located downstream of dams and the low lying regions. Flooding causes immense losses, which include loss of human and animal life, soil erosion, damage on properties, destruction of vegetation and many environmental damages. In addition, areas affected by floods are highly susceptible to famines and prolonged droughts. This further causes loss of human and animal life due to starvation. Floodwaters are usually contaminated with harmful microorganisms derived from raw sewage. This puts people affected by the floods at greater risks of getting infectious diseases (Proverbs, et al., 2011, p. 221). Floods may contribute to some positive impacts on the ecosystem. One of the benefits of flooding includes offering fresh water for domestic use and irrigation. The other benefit includes massive deposition of minerals and nutrients into the affected areas. Apart from these benefits, floods also help in improving the condition of aquatic ecosystems. However, they can be regarded as the most damaging compared to volcanic eruptions and earthquakes. Therefore, stringent measures must be undertaken to prevent the massive losses incurred during floods. This paper discusses various techniques used in controlling floods and their environmental impacts (Gruntfest & Handmer, 2001, p.12). Methods used to control floods Techniques applied in controlling floods entail the modification of the river environment and areas located close to the river. Flood control techniques can be applied on the river channel, floodway or on the floodplain (Ghosh, 1997, p.55). Techniques applied in floodplains Floodplains are those regions that lie below the flood elevation and exclusively on the floodway and river channel. Majority of techniques applied on the floodplains lie far from the river, but are designed to reduce damage from floods. Levee around structures This technique entails the construction of a levee/floodwall around structures located in floodplains. Levees can either be permanent or temporally. Construction of the levee requires the use of strong, natural or artificial material that can withstand pressure from the floods (Hyndman & Hyndman, 2010, p.356). The essence of using levees and other barriers is to raise the height in structures located in floodplains which floodwater must rise to in order cause flooding. These structures offer protection to structures but put other structures into a high risk of flooding due to increased water retention in the floodplains. In addition, serious damage to protected structures can arise when the levees are unable to hold back the floods. This is because the pressure at which the floods hit the structure is extremely high compared to when there is no barrier (Green, 2004, p.36). The use of levees, floodwalls, and dykes has a negative impact on natural river processes (Harmancioglu, 1994, p.42). Ideally, water spills emerging from a river should form a natural channel which provides a way for the floods to flow. Therefore, levees reduce the ability of the floodplains to process floodwaters. In addition, the ...Download file to see next pagesRead More

Garcia Marquezs One Hundred Years of Solitude

The dividing line between contrasting features cannot be drawn as it was the author’s intention to present reality through magical happenings and incredible events.  

Marquez’s novel refers to magical realism which is ‘a mode of narration that naturalizes the supernatural, that is to say, a mode in which real and fantastic, natural and supernatural, are coherently represented in a state of rigorous equivalence – neither has a greater claim to truth or referentiality’.2

The author tries to delete the demarcation line between reality and imagination, history and myth. The line between reality and fantasy is intentionally blurred. That’s why attempting to separate re...

A democratic political system is an essential condition for sustained economic progress. Discuss

What is now clear is that democracy is superior when it comes to countries that have a heterogeneous mix of people and cultures since it is imperative that all sections of society be carried along if the process of economic development has to succeed.

Explaining White-Collar Crime through Sykes and Matzas Neutralization Techniques and Mertons Anomie

Modern criminology indicates that the term is of no limitation by referencing to types of crime, which could be enumerated as a crime by the time of the offense, by the type of offender, and by organizational culture (Cote 2002, p. 202). White-collar crimes are generally not associated with poverty or pathologies relating to it. The legal definition of crime is viewed as the only definition of crime, in which the behavior being examined is punishable by law (Sutherland 1949, p. 84).

Sutherland (1949, p. 84) claims that persons belonging to the upper socioeconomic class are involved in such criminal behavior, which is characterized as different from the criminal behavior in which the lower socioeconomic class engage in p...

Stop Animation and the Comparison to Newer Techniques in CGI

As with many films, a great creative license is taken with the story, although it retains the original thrills and spectacle.

The great Ray Harryhausen created some of the most advanced special effects of the time within this film. The scenes are exciting and thrilling, although by today’s standards it is easy to spot the differences between what is created and what is filmed from life. Still, the special effects in Jason and the Argonauts are some of the best examples of Ray Harryhausen’s stop-motion animation available. The movie is a mythological creature that is the eighth collaboration between producer Charles Schneer and Harryhausen. Ray Harryhausen’s contributions included those of co-producer,...

What Are the Most Important Factors in Explaining the Rise of the Modern State

Though the existence of the state can be felt in different walks of everyday life, yet it is an intangible whose nature is impossible to grasp. As a political institution, state embodies the concept of sovereignty. Devetak (2007) describes it as a political unit or a country that possesses sovereignty. State can thus be described as a single, unified whole confined within territorial borders. The state is built in a core geographical area with allowances to a certain extent on the boundaries. According to Strayer (1970), a state exists in the hearts and minds of the people. The collective personality of the state renders it immortal. The state is a multi-faced concept that is fuzzy around its edges. Consequently, we cannot develop...

Weight Control as a Key to Self Improvement

To date, some 38 million Americans are “significantly heavier” than average, and because of this fact alone are targets for societal and institutional prejudice. People who are judged fat are discriminated against at work, school, in acquiring access to public accommodations, in applications for insurance, and access to adequate medical care. (Angier, 2005)

Many people take the words “obese” and “overweight” to mean the same thing. Actually, they are not. Overweight refers to an increased body weight (not necessarily increase in body fat) relative to height, above that which is generally accepted as a standard. (Capella University, 2004). Obesity, however, is “defined simply as...
