The purpose of the article was to convince the engineering community to take action so that engineers see how their projects impact humanity. The article succeeded in its purpose to bring attention to the problem of ignoring the affects that an engineer’s design can have on humanity. He points out several…
At the time of the Disaster, Stern's law firm (Arnold & Porter's) had decided to permit one partner each year to spend all his time on pro bono publico cases (public interest cases). The third year of the program it was Stern's turn.…
1. Why was the building of the dam first proposed in 1919 and by whom?…
The Hoover Dam does more than attract tourist, it provides power to 8 million people (32). Instead of using a heat source to create steam to turn a turbine like most power plants, hydroelectric plants use the natural flow of water and divert it through a turbine via a dam. The estimated available hydro energy in the United States, discounting wilderness preserves and the likes, is 65 gigawatts. One significant advantage of hydroelectric power in the U.S. is that there are existing dams across the nation that are not currently powered, thus possessing the immediate potential to add roughly 12 gigawatts to the 7% of the national power usage that the hydroelectric industry already supplies. The best place for a dam is at a significant…
As the heavy rainfall fell on mountainsides and already saturated soil, the water would then run off and go down the creeks and canyons toward the lowest point of the landscape, the Los Angeles River. (Roderick 1) The river began in the San Fernando Valley and the ranches and towns that were there located in that area were cut off by engorged canyon washes spilling their banks. All the bridges were being submerged and washed out by rapid amount of water riding. (Roderick 1) In the San Gabriel Mountains, after the gates opened on Big Tujunga Dam, the situation turned worse by releasing even more water across Los Angeles. The overflow that had came down was uncontrollable for the city of Los Angeles and continued to destroy many aspects as the rainfall continued until 7 p.m.(Liquid) March 3rd. Although the rainfall stopped, the mountains continued submerging the city of Los Angeles under inches of rain into the Santa Ana rivers and caused it to continuously rise and putting many citizens and victims in danger. This flood was considered a 50-year flood because it had a 2 percent change of occurring any given…

Hoover Dam, also known as Boulder Dam, is a concrete dam built in the Black Canyon of the Colorado River. It was built on the border between the states of Arizona and Nevada and it also crosses the border between two time zones, the Pacific Time Zone and the Mountain Time Zone. When it was completed in 1935, it was the world 's largest electric power producing facility and the world 's largest concrete structure. The dam is located about 30 miles southeast of Las Vegas. It is named after Herbert Hoover, who played a key role in its construction, first as the Secretary of Commerce and then as the President of the United. Construction of the dam started in 1931 and was finished in 1935, which was more than two years ahead of schedule. After many years after construction, Hoover Dam was officially called a national historical landmark in 1985. Behind the dam lies Lake Mead. This is the reservoir created behind the dam and was named after Elwood Mead, who oversaw the construction of the dam.…
You may be wondering how the dam burst in the first place. Well according to McCullough there were many factors. The dam itself had many internal flaws, like the fact that it sagged a bit in the very middle of the dam where it needed to be the strongest, it would not have been noticeable to the regular eye though. The dam was part of the South Fork Hunting and Fishing Club, which was a prestigious summer, mountain club. It had members such as Andrew Carnegie and Henry Clay Frick. The dam created a lake for the members of the club to go boating (which was very rare, especially in the mountains), but when the dam was being rebuilt for this club many things were overlooked. For example the fact that there was no way of controlling the amount of water it held, this meant that once they raised the level of the water there was no way to go back. There were also many small leaks that were overlooked, passed off as, “springs that came from near the ends of…
It is an extremely difficult task for engineers to design a “dam” like the Old River Control Structure in southern Louisiana so that they can be sure that it will prevent avulsion of the Mississippi into the Atchafalaya.…
During this time of the Great Depression, people lost hopes/luck and inspiration because of the great number of unemployment, homelessness and poverty. Building something big and great such as this dam helped to inspire people that America could come back and prosper during a weak and down…
The Colorado River is now being over utilized and if there were some unseen disaster this would put millions of people out of fresh water. They use the River as a plumbing system meaning that they channel the water and divert it all over the south west providing fresh water to thousands of farming acres. California how now over exceeded there its share of the allotment of fresh water taking in 800,00 acre-feet . With Utah and Nevada growing there becomes an ever increasing problem…

were made that still govern the Colorado River Basin to this day. A few of the more important laws governing the way water rights are allocated today are the Colorado River Compact, Boulder Canyon Project Act of 1928, Mexican Water Treaty of 1944, and Upper Colorado River Basin Compact of 1948. The Colorado River Compact was an agreement made by all seven states in 1922 (US Department of the Interior, 2008). This was responsible for dividing the basin into Upper and Lower basins and appropriating half of the water, 7.5 million acre feet (maf), to each section (US Department of the Interior, 2008). This compact would serve as the basis for what is known today as the “Law of the River”, future laws and compacts would simply be incorporated to…
It’s very sad that the Colorado River is drying up, because it has been there for thousands of years and it practically, provides us the water we use every single day. Without the Colorado River, life would be different here in the western United…
