Transcript of "Student Presentation: The Hoover Dam by Sid and Vic"

  1. 1. The Hoover Dam<br />By: Sid and Vic <br />
  2. 2. Need for the Hoover Dam<br />The Colorado River was growing out of control<br />Flooding increased rapidly<br />The surrounding states needed water to support people<br />Arizona<br />Wyoming<br />Colorado<br />New Mexico<br />Utah<br />
  3. 3. Serving the Public<br />Electricity<br />Supplies 1.3 million people with electricity <br />Water<br />Supplies surrounding states with drinking water<br />Flood Prevention<br />Prevents floods by holding water back<br />
  4. 4. Disservice to the Public<br />Releases Methane<br />Still water causes organic matter to die, releasing methane.<br />Riverbed Lowering<br />The pressure of the still water is digging into the riverbed<br />Destroys Natural ecosystems<br />Many animals lose their shelters<br />Water Quality is disturbed<br />
  5. 5. Methane<br />Methane is 25 times stronger than CO2<br />It is released by dead matter<br />Plants die due to no movement<br />
  6. 6. Riverbed Lowering<br />The riverbed is lowering due to the water building up<br />In 9 years, the water table sank 4 meters. <br />
  7. 7. Water Quality<br />The amount of dissolved oxygen is lowered because the water is still. <br />The temperature is cooler than the normal river. <br />
  8. 8. Engineering Challenges. <br />
  9. 9. Diversion Tunnels <br /><ul><li> Two 50-foot diameter tunnels drilled into the canyon.
  10. 10. The tunnels diverted the water around the dam while it was being constructed
  11. 11. The tunnels are a combined 3 miles in length</li></li></ul><li>The Canyon<br />The river over millions of years sunk down into the canyon<br />This created many crevasses and loose rocks, which had to be removed<br />Men called “High-Scalers” swung on swings on the cliffs to place dynamite into them to blast away the lose rocks. <br />
  12. 12. Building Materials<br />Use of quick-dry concrete <br />This called for the concrete to be required to be moved quickly from the production plant to the dam site. <br />If it was not moved quickly enough it would set, and had to be scraped out by hand. <br />
  13. 13. “It’s a dam controversy” <br />
  14. 14. Name of the dam <br />Originally named “Boulder Dam” <br />At its opening ceremonies, a person called it “Hoover Dam” and the namestuck <br />Changed back to “Boulder Dam” by the Sec. of the Interior<br /> Changed back to “Hoover Dam” in 1947 by Congress to honor President Hoover. <br />
  15. 15. Conspiracies <br />Hoover Dam is connected to Area 51 via underground tunnels <br />According to some conspiracy theorists, there is much alien activity at the dam, and there is a government complex in it <br />But the best one of all…..<br />
  16. 16. Conspiracies <br />there is definitely a government complex in the tunnels of the dam which houses robot alien technology, I’m not sure where this came from definitely not Transformers 2…. <br /> <br />
  17. 17. How can I get there?!?<br />
  18. 18. NCSSM >>– Hoover Dam <br />
