Dam Building on the Yom River
The proposed for Kaeng Sua Ten dam project has provoked controversy for more than ten years. Due to fierce objection from the locals, the government's aspiring aims to construct the dams in Phrae province's Tambon Sa-Iab may never leave the drawing board. The government declared that the dam was essential. It would reduce flooding, ease seasonal drought areas, and lead to agricultural development. Dams are a crucial component for industry and hydropower and attracting many local and international investors. On the other hand, the locals, fierce resistance of the project claimed that the project was ineffective and unsustainable. Furthermore, it would impair the ecosystem and livelihood of the villagers. They demanded for an effective precipitation in decision-making and conservation of Mae Yom National Park (Wongruang, 2012) . I strongly believed that the construction of Kaeng Sua Ten dam should be stopped as it is inefficient and unsustainable, it damage forest ecosystem, forest biodiversity, and livelihood of the villagers, as well as leaving little room for social justice .
First and foremost, Kaeng Sua Ten dam cannot successfully relieve flood, reduce drought or even generate electricity. In order for the dam to be able to control floods, it must be able to store a large volume of the water. Hence, the reservoir must be empty to store sufficient floodwaters. However, it is not possible. Kaeng Sua Ten is a medium-sized dam, which has a capacity of around one billion cubic meters of water. It has a certain amount of water at all time to generate electricity (Eamwiwatkit, 1996). This means that the dam is unable to aid the local during the period of drought. The water is not supp...

There are nine dams in and directly leading to New York State’s Letchworth State Park. These dams have been built for a variety of reasons and affect nearly 400 miles of freshwater rivers in the Genesee River Basin of Western New York (Fish, n.d.).
Furthermore, even though the Friend dam is the first primary purpose of it; it also follows a secondary purpose also. And that would be the Friend Power Authority which has 4 power plants. And within the plants it has turbines in it. What this turbine does it is that it generates water into the channel or tubes, and then it let it out into the four outlets which flows out into its benefits locations.
Yet this is not the only example of the failure of Mississippi river management. Only 10 years ago, New Orleans’ levies failed, an example of the inability to control the flooding.
The negative aspects of Glen Canyon Dam greatly exceed the positive aspects. The dam’s hydroelectric power supply is only three percent of the total power used by the six states that are served by the facility. There is a surplus of power on the Colorado Plateau and with more and more power-plants being created in the western hemisphere, Glen Canyon Dam’s power is not needed (Living Rivers: What about the hydroelectric loss). Although the ‘lake’ contains twenty seven million acre feet of water, one and a half million acre feet of water are lost yearly due to evaporation and seepage into the sandstone banks surrounding the ‘lake’ (Living Rivers: What about the water supply?). The loss of that much “water represents millions, even billions of dollars” (Farmer 183). If the government were to employ more water efficient irrigation practices, as much as five million acre feet of water per year could be saved.
Based on the events that lead to the devastating floods in Queensland and the eventual case that was brought against the engineers of the dam, there have been views from both sides of the divide as to whether or not the actions taken by the engineers were actually ethical or otherwise. We have explored this avenue and have found that both sides of the divide have good reasons to justify their actions. Firstly, we shall explore the avenue that the engineers decisions were appropriate and ethical. It can be said that the engineers did employ act utilitarianism in their decisions and actions, hence causing these decisions to be ethically correct. Act utilitarianism is essentially doing the right thing, which would benefit the majority of people, based on the situation that is currently taking place. One of the reasons that explains why the actions taken could be considered as ethically fine, was that if the dam was not opened, there would have been no other way to solve the increasing water levels in the dam. If no action was taken, there could have been seriously devastating effects, like the dam wall eroding due to water spilling over the dam wall, thus weakening the structure, or a loss of water flow control. Professor Hubert Chanson, a professor in hydraulic engineering in the University of Queensland, mentioned that the Wivenhoe Dam was actually designed as an embankment dam, hence it should not be overtopped, that is water should not be allowed to flow over the limits of the dam (Andersen 2011). Despite there being a secondary spillway, however it is recommended that spillway is not put to use, as the use of that spillway would mean that there would be a surge of water leaving the dam, and a loss of control of the water flow, w...
Americans today tend to believe that the Colorado River drought has been a recent occurrence, although drought relief strategies have been implemented since early 1997. To summarize, in the book The Colorado River Basin Drought Planning and Organizations, Colorado is named as the original state to acquire a drought relief plan. For instance, various assume water levels are diminutive in the Colorado and blame is due to the previous ten years of drought throughout the United States. Although it is true that water levels are at a record low, initial plans in the early 1920’s to introduce manufactured structures into the water basin is the original reason Colorado’s water system began to be compromised. It follows, then the supplementary natural

According to Chief, his father decided not to argue with the townspeople’s decision, “The way Papa finally did when he came to realize that he couldn’t beat that group from town who wanted the Government to put in the dam because of the money and the work it would bring,” (page 150). This means that people wanted the dam to be built because of the advantages and products that they can get like money, electricity and much more. They were being selfish people and didn’t care about what happened to the tribe. Not caring about the children who would be taken from their homes, the families who would have nowhere to go; homeless, without food or shelter. All they wanted was their well being, that was very cruel of them. Another example is when a woman looks for Chiefs father when he was younger, “I think if we just leave now and go back into town, and, of course, spread the word with the townspeople about the government’s plans so they understand the advantages of having a hydroelectric dam and a lake instead of a cluster of shacks beside a falls,” (Pg. 182). This shows how desperate the people were to get the dam. The woman thought that Chief was dumb and didn’t understand English and they were talking about what they were going to do with the village and convince the townspeople to build the dam. On the other hand, the Indians thought the

...ouse also. In Indonesia, corruption is widely present. The organization may request a sum of money from the government to solve the flooding issue, although, the leaders of the IFPP could possibly choose to pocket the money for their own use, instead of properly solving the flood issue in Solo. Due to corruption, the money remaining wouldn’t be able to be suffice for the construction, therefore they have to minimize the use of resources which could lead into a weaker dam, or they have to build a smaller dam which couldn’t decrease the flood levels as much. Although problems like corruption is there, the dam system would be an effective method because the flood levels are getting controlled, and the hydrological power would be able to be supplied to the people, therefore slowly covering their costs, and resulting into a highly effective method for the people of Solo.
There are many solutions for the future that could be done. Dams along the Mekong threaten many things on land and in the water. When fish migrate in the Mekong they are mostly anadroumos fish, so they go upstream. Since there are dams all along the river it is hard for these fish to try and go upstream. They cannot go through the dams but if each company invested money on a fish ladder this problem could be solved. The fish could go right up and around the dams and make it to the other side and migrate freely. Also, they should make fish screens so they can pass safely through the turbines. This is also hard to do for the companies because they need to make money. Another idea that they could do would be to refrain from using power during the migration season and let the dam flow freely. This would allow the migration of fish and set the back to normal for some time. All of these ideas are not as acceptable as not having a dam, but they are alternatives which are better than having one all season and not letting fish by the dam. These solutions for dams are real ideas that people could do. They would help the ecosystem of the lake and make the dam friendlier to the people and the environment.
