South Fork Dam

I have learned about the Portland’s water system in the first of a few weeks. I have learned the Portland’s water resources, water quality management, history of water system, water transportation system, and water issues in Portland area. Now, I compare Portland’s water system to another city in the United States. I pick up Seattle’s water system because I lived in Seattle for two years before I move to Portland, and I’m interested in the Seattle’s water system. In this journal, I write about the

failed dam, rushed into the city of Johnstown, Pennsylvania. In its wake, most of the town was destroyed and more than 2,200 lives were lost. The Johnstown Flood was one of the worst natural disasters ever seen in the United States and brought in relief from all over the nation and world. For Clara Barton, the Johnstown Flood disaster was the first test for her newly formed Red Cross. About 3:00 p.m. on May 31, 1889, water had backed up to the point where it began to spill over the South Ford Dam. It

water everywhere! This is prime time to witness Sierra water on the move. There are, of course, many destinations in Tuolumne County to see the spectacle of snow melt, but one of my favorites is Rainbow Pool and the nearby collision on the South and Middle Forks of the Tuolumne River. The merging of these two streams is mesmerizing, even more dramatic because you are able to stand so close. Drenched with spray and the sound and fury of the rivers blocking out all other sounds, it is an experience

just like a lot of our nation's laws and systems we have in place they are written because of the blood that came from a scenario that we have to fix. The background of this case study is that in 1889 the city of Johnstown, Pennsylvania the South Fork dam north of the town was not inspected or maintained regularly. therefore, the infrastructure

Introduction Rivers and streams receiving urban runoff have been shown to be toxic to aquatic species (e.g. H. azteca), due to the presence of pyrethroids (Budd et al., 2007; Weston and Lydy, 2010; Weston et al, 2014). These pyrethroids are greatly toxic, with acute species mortality possible at even small concentrations of one part per trillion (Weston and Jackson, 2009), yet urban runoff regularly contains concentrations greater than 20 parts per trillion (Weston and Lydy, 2012). A significant

The episode is about how Andrew Carnegie impacted America. Carnegie built the industry of mass steel productions. He started on working on railroads, and soon helped build and envision some of the great buildings in America. It all started when Carnegie worked for Tom Scott as a child to make extra money. He learned a lot about business and became interested because of him. Later on, still employed by Tom Scott, Carnegie had a vision on building a bridge made of steel over the Mississippi river

Bretz presented evidence that there was at least one exception to this rule-namely the geologic formations of the Columbia River Basin and the Channeled Scablands. He proposed that a glacier caused an ice dam that blocked the Clark Fork River, creating Glacial Lake Missoula. He thought that the ice dam would

Response Paper of the Johnstown Flood “Johnstown flood” is a short story written by David McCullough. This story talks about the miraculous survival of a little girl named Gertrude. Gertrude’s sheer luck got her up the hill safely. Of course, with the help of several people she met along the way. I think that this is an extraordinary act of how worked together and some people put his/her life at risk to save a small child that they didn’t even knew. I fell that this is a great example of how

The internal and external anatomy of Labeo umbratus Hannah Janse van Vuuren Abstract The anatomy of an Labeo umbratus specimen, found in the Krugersdrif dam, was studied. Annotations of the positions of the internal organs as well as the external morphological characteristics were made. Upon further analysis, several characteristics were identified that would have eased life in aquatic environments. Some of these characteristics include, sensory receptors located on the head as well

houses and towers; erected 3,959 miles of telephone lines; built 1,469 miles of roads; constructed 387,208 check dams for erosion control; planted 36,091,000 trees; fought forest fires; and helped build the first state parks . The CCC was involved with the development of 19 state parks totaling 108,608 acres5. These parks include but are not limited to Pickett, Reelfoot, Frozen Head, Norris Dam, Big Ridge, T.O. Fuller, Booker T. Washington, Harrison Bay, Cove Lake, Pickwick Landing, Cumberland Mountain
