The article, ”Oroville Dam: Dramatic photos show damage to dam’s emergency spillway,” by the Bay Area News Group describes what is happening currently with the Oroville Dam situation. The article is featured in “The Mercury News” which for the most part seems to have a good journalistic reputation, aside that all their negative reviews seem to be about a bad delivery service. The Mercury News also seems to have a conservative orientation in their articles. The authors, Bay Area News Group, is an accredited news group by the Better Business Bureau. The articles describes the current status of the dam situation. As of Sunday, the water level of the reservoir was 852ft, 49ft less then when the dam first started to be in danger of overflowing.
10. Although. Over a million people have been displaced by the dam already. What is the future forecast for local citizens? Is the social turmoil over yet?
One thing that stood out to me was the article about the Chinese company that is 3-D printing houses. This is done by using recycled materials, and printing parts of the house and then put together like a puzzle. I knew houses were being 3-D printing but I didn't know that they are able to print houses within 24 hours, let alone 10 houses within 24 hours according to this Chinese company. This potentially could be a great thing for many undeveloped countries in the world who could use this type of technology.
The Nile River is in jeopardy because of a dam. In 1843, a dam was about to be built across the Nile. The dam was 12 miles down to the city of Cairo. The dam was what everyone was talking about for a while, although it was completed in the year 1861. After the dam was built, it was then extended and improved, it was marked as the beginning of the modern irrigation in the Nile Valley. In the year 1901, the Zifta Barrage was added to the system. Only a year later, in 1902, the Asyut Barrage was more than 200 miles upstream from Cairo. Then there was the first dam at Aswan that was built between 1899 and 1902. After years and years, the dam has been enlarged. In 1929 and 1934, the water level rose, but the dam's capacity increased. The Aswan Dam was located to 600 miles upstream from Cairo and 4 miles upstream towards the real Aswan dam that was created. What was really the dam job? It was to control the Nile water, so the crops could get provided with water. All of this hard work started in 1959 and then completed in
The struggling citizens of the southwestern states survived the Great Depression in great part due to the construction and final completion of the Hoover Dam, an engineering marvel. Due to the fact that the Hoover Dam is located on the boarder of Nevada and Arizona, it is extremely hot there. During this time period, the citizens living in these dry climates pushed for an irrigation system that would benefit these desert surroundings with flooding protection and something to act as a utility to help provide power to the growing cities nearby. The best answer to this was the Hoover Dam, which is located on the Colorado River on the boarder of Nevada and Arizona. In only five years, the completion of the Hoover Dam was constructed from 1931 to 1936. The costly construction of the Hoover Dam was a successful project that was completed during the Great Depression which contributed to the benefit of political policies, economic situations, and environmental concerns.
I believe that the Hetch Hetchy Dam should remain in place because national resources and utilization of these resources can co-exist but we first must affirm the federal land act in which it states that it "recognizes the value of our Nation’s public lands and provided a framework in which they could be managed in perpetuity for the benefit of present and future generations." To maintain the Hetchy Hetch river valley for the present they should not disturb the ecosphere that is now in place. To do away with the dam there will be damage to the surrounding areas and be pro active in controlling any erosion and stabilization of the valley if it was drained. The vegetation and the original beauty will take many years to be reintroduced
The seismic-gap prediction method would have been effective before the 1989 Loma Prieta. It would have allowed for time to prepare for the events ahead of time. It would have also been a good tool for construction workers to build housing and parking garages with different material, that would have been more solid for structures to withstand the earthquakes better. The areas that look dangerous now, south San Francisco in the Crystal Springs Reservoir.
In CBS’s article, “At least 13 dead as wildfires devour wide swaths of Northern California”, it seemed very dramatic. CBS seems to appeal more to ethos in comparison to the Fox News article. They gave more facts, more interviews, and in-depth descriptions. However, the site does not tell the readers who the author is, so that makes them a little less credible. On the other hand, the author does not use any logical fallacies in the article. This brings back some credibility. Not to mention, CBS has quotes from seemingly credible sources like Vice President Mike Pence, and homeowners affected by the fires. The short interview of Vice President Pence tells the readers what the president is doing about the situation, and seems to ease troubled minds with facts and emotion.
(1.) The ride sharing service, Uber, is a successful and disruptive service in the car service industry; however, the business model creates a dynamic situation for individual Uber drivers. According to Bales and Woo (2017), Uber drivers are independent contractors who do not receive the same benefits as taxi drivers, including protection from individual liability. While debate exists between the drivers and Uber over the employee or contractor classification, Uber asserts that the legal obligations fall upon drivers due to the freedom associated with drivers’ work hours. Due to the risks of liability from vehicle incidents, Akalp (2015) recommends that Uber drivers set up a limited liability corporation in order to protect drivers from losing personal assets in the event of being sued in contractual disputes. In addition, Akalp (2015) recommends that an S Corporation tax status provides a more convenient
There are many dams that are currently in critical condition in the United States. A dam is defined in critical condition when a dam failure would cause loss of human life and large economic loss (FEMA). According to a study of dams by the American Society of Civil Engineers, “As of 2012,
Analysis of the dam shows that it was not in compliance with The World Commission on Dams (also known as the WCD). The World Commission on Dams priorities for their guidelines on dams are as followed: Gaining Public Acceptance, Comprehensive Options Assessment (such as Environmental, Social, Health, and Cultural impacts, Life Cycle assessment, And greenhouse gas emissions), Addressing Existing Dams (such as Improving reservoir Operations), Sustaining Rivers and Livelihoods (such as
On May 19 and 20, 1990, terribly significant rains fell within the river Basin, particularly over the lower finish of Lake Hamilton and far of Lake Catherine. within the twelve-hour amount from 6:00 p.m. May 19, 1990 to 6:00 a.m. May 20, 1990, there was downfall of 10 inches at Carpenter Dam, seven inches at Remmel Dam, and twelve inches in near Hot Springs, with most of the rain falling between 8:00 p.m. and 3:00 a.m. The pool elevation on Lake Hamilton was 399.16 feet higher than water level at 8:00 p.m. on May 19, however when four hours, had up to 402.12 feet, and was still rising. Throughout this point the gates on Carpenter Dam were opened so as to avoid flooding on Lake Hamilton. The mixture of the discharge from Lake Hamilton and therefore the influx of rain from Lake Catherine's catchment area flooded the shores of Lake Catherine. The tail water from Carpenter Dam rose from a traditional elevation of 305 feet, to an elevation of 331 feet by 4:00 a.m. on May 20. Before the flooding, the pool elevation at Remmel Dam was close to traditional at 304.33 feet, however the pool at Remmel Dam crested at 7:00 a.m. on May 20th at 4:00am at an elevation of 317.50
Just as we thought the problems of flooding had stopped, the 400 mile long reservoir of the Three Gorges Dam has flooded 13 cities, 140 towns, 1352 villages, and 100,000 acres of China’s most fertile farm land.
It was built in the beginning of the 1950s, and was finished in 1958. By the year 1963, it was completely full and it had over flown. The dam, unlike many others of its kind, is not used for irrigation or water supplies but solely for generation of hydroelectric power.
The initial water balance suggests that the water balance for the reservoir (i.e. the net change in water in storage) was 10450 ML / Year, and one of the proposed industrial plants is seeking a permit to extract 1825 ML / Year from the reservoir.
Once the level within the dam surpasses certain level, the dam is at risk of collapsing. To avert this, we ought to constantly monitor dam level to ensure that dam structure doesn 't cave in underneath the pressure from the water. A dam is really a barrier that impounds water or subterranean streams. The primary water quality related parameters that should be supervised are Temperature, Turbidity and ph. This paper describes the theoretical aspects associated with the work we 're doing and also the particulars concerning the illustration showing the automation of dam gates. Dams generally serve the main reason for retaining water, while other structures for example floodgates or levees (also referred to as dikes) are utilized to manage or prevent water flow and drainage into specific land regions. You can do this by manipulating the ton gates when the level surpasses certain limits.
