INTRODUCTION According to tree ring scientists from the University of Arizona in Tuscon, the Colorado River went through a six decade long drought during the mid-1100s. This drought was longer than any other drought know to the region. The Colorado River is essential to the American Southwest, draining into about 242,000 square miles of land to include seven U.S. states: Arizona, California, Colorado, Nevada, New Mexico, Utah, and Wyoming. “The Intergovernmental Panel on Climate Change predicted in a recent report that the Southwestern U.S. Will become hotter and drier as the climate warms.” With human caused climate change and run off reduction, it has been predicted that the Colorado River could become dry by 2012. Discussions in this paper will include a general history and how the American Southwest relies on the Colorado River for survival, how climate change is effecting it, and management efforts to curtail conflicts between vying interests over a shared water source.
The Dams: 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.). The Elitsac Manufacturing Company Dam affects 14.08 miles of Wolf Creek (Fish, n.d.). The original purpose of this dam is not documented within the state’s dam inventory, and it is also no longer in service (Dam, n.d.). Another dam on Wolf Creek is Hopkins Mill Dam, which also is out of service.
US stretching to Illinois, Indiana and Ohio. The flood had a property damage that exceeded $2 billion dollars and also a total of 37 people who died, despite the many warnings received. This epic event was considered as the 100 year flood that western and middle Tennessee had been expecting since the last widespread flood occurrence. The Cumberland River which is a major waterway that crosses through north-central Tennessee accumulated so much rain, that it resulted in a crest increase in Nashville at 51.86 feet, 12 feet above the flood stage. The heaviest rainfall occurred across Davison, Williamson, Dickson, Hickman, Benton, Perry and Humphrey’s counties, which translated into an average of 14 to 15 inches of rain, which are equivalent to 420 billion gallons of water in just two days.
This research paper will examine the human populations, abiotic factors and natural areas of Klamath County and later focus on the environmental issue of companies attempting to clear cut the surrounding forests of Crater Lake. Human Populations The county seat and largest city is Klamath Falls. The current population is 42,000 (City of Klamath Falls, 2013). This city was originally named Linkville because of the Link River and was later changed to Klamath Falls because of the beautiful falls nearby (City of Klamath Falls, 2013). It was also named “Oregon’s City of Sunshine” because of the 300 days of sunshine they get a year (City of Klamath Falls, 2013).
The Colorado River is the seventh longest river. In the 1920’s Western states began dividing up the water in the Colorado River by building dams and divert river flow to San Diego, Phoenix, and other large cities in order to supply water to these cities. In the past the river has been known for being a major source of water and electricity. The Colorado River passes through Utah, Arizona, Colorado, Nevada, California, Baja California, and Sonora. During the past decade a drought has been sweeping the Southwest resulting in a lowered river level.
This past summer, seasonal floods across Pakistan killed more than 67 people and displaced thousands. Similar events has been constantly plaguing millions of people in Pakistan for the past five years, where this country has experienced unusual severe monsoon rains in the summer. One of such event was the devastating floods in 2010, which displaced an outrageous 11 million people. This report will examine how much impact the 2010 floods had on Pakistan 's population and it will inspect the displacement this devastating disaster caused. Furthermore, this report will also explore the economic and social consequences of the floods, reasons for migration, different types of migration, issues caused by migration and obstacles preventing the population
There were a record number of deaths, which range from an incredible a hundred and forty five thousand in a day to Four million people overall. After further research they figured about a million people drowned and more than 3 million died from disease and starvation. The most affected areas were the Yangtze River, the Huai River, and the Yellow River. Some of the most rainfall happened between July and November in 1931; China experienced some strange weather. In the years running up to the disaster, China had been suffering from a long and hot drought throughout the whole country.
• 2000- The 2000 Mozambique flood was a natural disaster that occurred in February and March 2000. The catastrophic flooding was caused by heavy rainfall that lasted for five weeks and made many homeless. Approximately 800 people were killed. 1,400 km² of arable land was affected and 20,000 head of cattle were lost.
Soon traders from India sailed to Europe and infected almost the entire continent. (Ziegler 121) This case was the most famous because of the large number of deaths affiliated with its outbreak. An estimated twenty five million people, one third of Europe’s population, perished during the plague’s four years of existence. (Janis 1) Government, trade, and commerce in Europe almost came to a halt. The Black Death caused the depopulation of about 1,000 villages in England.
The flood itself had been the worst seen in the city since 1557, four hundred and nine years earlier. Flood Triggers The trigger for the flood was attributed to the intense rainfall beginning around noon on November 3rd and lasting until the evening of the following day.
