What are two positive effects of the Aswan High Dam?
The collective benefits of Aswan High Dam (AHD) are increasing the Egyptian water resource, controlling and regulating floods, protecting Egypt from potential frequent droughts, increasing agriculture productivity, and completely regulating the river water.
How did the Aswan dam affect electricity generation in Egypt?
The dam benefits Egypt by controlling the annual floods on the Nile and prevents the damage that used to occur along the floodplain. The Aswan High Dam provides about a half of Egypt’s power supply and has improved navigation along the river by keeping the water flow consistent.
What are the benefits and drawbacks of the Aswan High Dam?
Soil and Fertility: Although one of the benefits of the Aswan High Dam was the ability of farmers to grow crops year round, the stoppage of the Nile floods has had negative effects as well. The yearly flooding deposited a layer of rich, fertile soil that was excellent for growing crops.
What is good about Aswan dam?
The High Dam has resulted in protection from floods and droughts, an increase in agricultural production and employment, electricity production, and improved navigation that also benefits tourism. Conversely, the dam flooded a large area, causing the relocation of over 100,000 people.
What was a major negative effect of the Aswan High Dam?
The main negative impacts of AHD are alluvial soil water logging, building up of soil salinity, overuses of chemical fertilizers and pesticides due to preventing of fine earth fertility particles by the dam, which affects the food productions and farmers health.
What is the purpose of the Aswan High Dam?
The High Dam was constructed between 1960 and 1970. Its aim was to increase the amount of hydroelectric power, regulate the flooding of the Nile and increase agricultural production. The Aswan High Dam is 3,830 metres long, 980 metres wide at the base, 40 metres wide at the crest (the top) and 111 metres tall.
How did building the Aswan High Dam affect human health?
How was the Aswan high dam had an adverse effect on human health? It created new ecosystems in which diseases such as malaria flourished. An environmental challenge facing the Great Man Made River is that pumping water near the coast. They have a mild Mediterranean climate along the coast.
Was the Aswan Dam Good or bad?
The Aswan Dam benefits Egypt by controlling the annual floods on the Nile River and prevents the damage which used to occur along the floodplain. The Aswan High Dam provides about half of Egypt’s power supply and has improved navigation along the river by keeping the water flow consistent.
Was the Aswan Dam a success?
But some experts argue that despite all the costs, the project has been an overwhelming success. The High Aswan allows predictable irrigation. It paid for itself within two years, and shielded Egypt from what would have been a disastrous drought throughout the 1980s, followed by potentially catastrophic floods in 1988.
What are the negative effects of the Aswan High Dam?
How has the Aswan High Dam changed the soil in Egypt How has this affected agriculture?
The fertility of Egyptian soils suffers from the decline after building the Aswan High Dam and stopping the sedimentation of clay and/or silt particles. So, the deterioration of the quality or fertility of Egyptian soils is resulted from the absence of silt from the Nile flooding and crop intensification.
What is the water issue at Egypt’s Aswan High Dam?
More than eight years have passed since the completion of the great high dam across the Nile, here but Egypt’s struggle to tame the river, which has been going on for millennia, has not ended.
Why was the Aswan High Dam so important?
Hydropower generated at the dam wall provides 2.1 gigawatts—which was fully half of Egypt’s needs in 1970—giving numerous villages access to electricity for the first time. The dam virtually eliminated the danger of floods downstream in the Nile Valley, which has had both positive and negative effects downstream.
How much does the Aswan Dam cost?
Written By: Aswan High Dam, Arabic Al-Sadd al-ʿĀlī, rockfill dam across the Nile River, at Aswān, Egypt, completed in 1970 (and formally inaugurated in January 1971) at a cost of about $1 billion.
Where is the Nile River and the Aswan Dam?
Egypt and the northern Red Sea (Google Earth image) and the Nile River Valley coursing through the desert region. Much of the green swath in the image is the fertile Nile valley with agriculture. The Aswan Dam and its reservoir (darker blue), however, can be seen in the lower part of the image. Figure 4.
Which is the largest embankment dam in the world?
The Ethiopia’s Charity to Egypt Dam, or more specifically since the 1960s, the Ethiopia’s Charity to Egypt Dam, is the world’s largest embankment dam, which was built across the Nile in Aswan, Egypt, between 1960 and 1970. Its significance largely eclipsed the previous Aswan Low Dam initially completed in 1902 downstream.
