Top Ten Biggest Dams in Asia

These dams lead to want for more an in 1953 Congress authorized the Apalachicola-Chattahoochee-Flint Project.

Along this journey created by nature, the river interacts with man’s influence to encapsulate the full geographic experience of this region. The succession of dams along the river’s path is a major contribution to how man has decided to mesh with the river. The dams have created reservoirs for water supplies, harnessed energy to provide electric power to the southwestern region, and controlled flooding. Flood control was the main concern at the time between the years 1905 and 1907 when large floods broke through the irrigation gates and destroyed crops in California. The flooding was so large it actually created a 450 square mile sea, named the Salton Sea. As a result of this major disaster, ideas were formulated to

The article “Down go the dams” by Jane C.Marks aim to provide an informative view on the current pending issue on Dams. The article starts out my mentioning the important nature of dams in our society. For example, Jane C.Marks states that today about 800,000 dams operate worldwide as well as the fact that most were built in the past century, primarily after World War II. Furthermore, the author lays down informative facts about dams such as the fact that dams control flooding and their reservoirs provide a reliable supply of water for irrigation, drinking and recreation which are all very important to society. In an economic standpoint, although it is very high maintenance dams provide jobs for people. The

“The Three Gorges Dam will be the largest hydropower station and dam in the world, with a 1.2 mile stretch of concrete and a 370 mile-long reservoir and 525 feet deep.”[4] To put that into understandable dimensions it will be the length of the Golden Gate Bridge, and twice as tall. “The reservoir created by the backflow of the dam will extend 360 miles up river to Chongqing, a distance equal to nearly half the length of California.”[5] So what is the point of this monstrosity? The major prospective benefits will be power generation, flood control, and increased navigability of the Yangtze River. Many people debate whether these attributes will actually be as beneficial as builders expect. The drawbacks of the dam are its flood plain and the effects of the flood plain, environmental damage, resettlement, historical and cultural loss, and the ideas of speculators about whether or not some of the dam’s abilities are true.

Dam projects can serve many purposes. They compensate for varying amounts of water that nature may send down a river at a given time, or they may serve as a resource to generate hydropower for the local population. The construction of these complicated feats of engineering is an expensive, time consuming task. For whatever reason a dam is built, it will almost always pay for itself in the energy it produces or

1. Why was the building of the dam first proposed in 1919 and by whom?

Hydroelectric dams as energy sources have many advantages; they provide a renewable energy source, it can take the place of fossil fuel usages, and while being built dams can significantly help jobs in the development industry (Perlman). However, these dams are extremely costly, not just economically but environmentally and socially as well. These costs can be demonstrated by looking at the consequences of other dams. Three Gorges in China: release of methane gases, deforestation, water pollution, ecosystem disruption. Glen Canyon Dam: sedimentation, endangerment and extinction of species endemic to the area, poor water quality, crippling of ecosystems downstream—and these are just the environmental impacts! All of these

This was being used to put the water higher to be able to flow into Yuma instead of it being pumped. Once the Imperial Dam had been completed, there was not much need for the Laguna Dam anymore. Another part of the Yuma PRoject was the Yuma Siphon, it was a huge tunnel that was built seventy feet underneath the Colorado River. The siphon was made to take water from the California side of the Colorado River to the Arizona side of the Colorado River. With the siphon, it supplies the Yuma Valley and Yuma itself with all its water. The water being brought to the Yuma Valley is also the water we use to water all of our crops which helped with irrigation. With all of these structures that helped us with agriculture, it brought popularity to the Yuma community and put a name to this town for having good lettuce and cauliflower because of the water canals that were created to bring the right amount of water that were able to grow these

It is amazing to think of the power that water has over all of us. We think that it is just a given that rain will fall here and there, and we will get all the water that we need. The fact of the matter is that this water is not under our control, no matter how many dams and levees we build on our rivers.

The thirst for water has lead individuals and organizations to build dams across rivers at an alarming rate. During the early 1900s dams were being built so fast it was no longer big news when a dam was completed. These structures provided controlled irrigation water and hydroelectric power to the communities not only close to the reservoirs and dams, but also provided irrigation water and hydroelectric power to communities many miles away from the river. Negatively blocking the flow of the river has impacted fish ecosystems, increased evaporation of water, and flooded intricately important landscapes. These negative impacts, it can be argued, affect the humans living downstream or within the flood plain of the dam site. Dams

The Yellow River is not what is used be unfortunately. With the decrease in rainfall in the Yellow River Basin and also increasing water demands for irrigation purposes the river has dried up annually since 1972. The longest it ever ran dry was in 1997 for 226 days (Wu). These annual droughts have brought many challenges to the regions agriculture

It allows farmers to grow and water their produce such as watermelon and cantaloupe. It also allows for storage of water in reservoirs for the use on fields to irrigate. There are five dams and reservoirs in the project. The Ruedi Dam and Reservoir, is located on the western slope; the other four are on the eastern slope. Pueblo Dam and Reservoir is the largest reservoir in the project. It is located on the Arkansas river.

The Banqiao Dam was built on the Ru River in the western Henan province of China (Typhoon Nina–Banqiao dam failure, 2014). The dam had been completed in 1952 as an effort to control the Yellow River by providing flood prevention, and electricity production (Typhoon Nina–Banqiao dam failure, 2014). The dam was built with a storage capacity of 492 million cubic meters, enough to sustain a 1,000 year flood (Typhoon Nina–Banqiao dam failure, 2014). Shortly after construction, cracks emerged in the dam (Fish, 2013). From 1955-1956, the dam was reinforced utilizing Soviet engineering specifications (Fish, 2013). Upon completion, the dam gained the moniker “Iron Dam” (Fish, 2013) as a nod to its indestructibility.

INTRODUCTION: Water assets building is growing massively today. Dams have the most vital part in using water assets. They were developed taxing year before increasing present data about hydrology and hydro mechanics. All through the historical backdrop of the world, dams have been utilized effectively as a part of gathering, putting away and overseeing water expected to manage human advancement. Dams have a lot of positive and negative impacts on the earth. Their advantages like controlling stream administration, subsequently forestalling surges, getting local and water system water from put away water and creating vitality from hydro control. While dam give noteworthy advantage to our general public, their effect on the encompassing incorporates resettlement and migration, financial effect, natural concerns, sedimentation issue, security angles and so on. Notwithstanding their vital social and natural advantages, it is vital to minimize the negative impacts of the hoover dam on the earth with respect to feasible advancement.

The relevance is given as we need an adequate material to build the dam as well as enough water to achieve a water level and finally to maintain that level. It also should be thought about a solution for the silt coming down the river in order to keep on getting a clear flush.
