Aswan Dam

The Hoover Dam site on the Colorado River between Arizona and Nevada and the Aswan Dam site on the Nile River in Egypt are examples of good locations for the harvesting of hydropower. Today, most of the good sites for hydropower are already developed. In most places, there is little hope for further significant expansion of this energy source. The only large hydropower facility currently under... 

Rift Valley fever is also transmitted by mosquitoes of the Aedes family, and an epidemic, in the early 1970s, in Egypt affected more than 200,000 people, with 600 deaths. On this occasion, the precipitating event was the construction of the Aswan dam, with the associated increase in water available for mosquito-breeding areas. 

Another possibility is to site ammonia production plants in regions where cheap hydroelectric power is available. This has already happened, long ago, in Norway, Canada and Egypt (Aswan Dam.) Other remote areas with untapped hydropower include Alaska, Iceland and Brazil. As one moves to more remote sites of hydropower, it may be advantageous to pipe the hydrogen to a more convenient location to build a chemical plant rather than to process it in-situ. 

The concept of development on the basis of megadam projects began with the Aswan Dam in Egypt in 1902 following Garstin s hydrological surveys between...

The climate of the Nile Valley was stable and predictable prior to the construction of the Aswan high dam. Although the effects of annual inundations were removed with the construction of the dam, the ensuing climatic changes ushered in a new set of phenomena that threaten the Nile Basin and its people, from Alexandria to Aswan. Our investigations (to be published) indicate that, because of overall increased irrigation, this threat now extends as far south as Khartoum. 

Most installations were comparatively small in size, with a few notable exceptions. At the Aswan High Dam, for instance, 40,000... 

In the last 150 years, world population has grown fast and our modern standards of living depend on the production of electricity, and production of food for at least two seasons a year. In an effort to meet these demands, engineers have built small as well as very large dams. In certain areas, very large man-made lakes have been dug in the earth, such as behind the Aswan High Dam in Egypt, the Ataturk Dam in Turkey, and new dams on the Yellow River in China.
