What is the history of the Aswan Dam?
There are two dams at Aswan and both have power stations. The first dam was constructed in 1902 at Aswan to confront flooding. This was totally inadequate and in 1956 a new dam was set up south of Aswan called the Aswan high dam. The Aswan high dam was completed in 1970. It is 3600m long and 111m high.
What are the benefits of the construction of the Nile dam?
Building the dam has allowed navigation to be more controlled and that has helped to boost the port cities along the river. Because the Nile drains into the Mediterranean Sea, major shipping lanes are suddenly open to these communities and they can import or export to the rest of the world. It helped to create a new industry.

What is one 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 are some of the negative effects of the dam?
Dams change the way rivers function. They can trap sediment, burying rock riverbeds where fish spawn. Gravel, logs, and other important food and habitat features can also become trapped behind dams. This negatively affects the creation and maintenance of more complex habitat (e.g., riffles, pools) downstream.

The dam has controlled the flooding of the river Nile in Egypt which used to threaten life in the lower Nile.
What happened after the dam was built?
After the dam was built, the nutrient levels that funneled into the Mediterranean were greatly reduced. In return, this mean that there were less fish available, so fishing in the area was dramatically reduced. It forced the relocation of over 100,000 people.
How does the Nile River help the environment?
It has helped contribute to higher levels of erosion. When the Nile River would flood, it would do more than provide farmers with fertile soil that could be used for planting. It would also help to replenish the silt that sits along the banks of the river that are naturally eroded by the movement of the water.
Why did the Nile River flood?
For thousands of years, the Nile River flooded to provide the desert landscape with fertile soil that could be used for growing. It’s flooding was predictable, provided farmers with resources, and was often the only source of irrigation. The building of the Aswan High Dam changed all of this by preventing the flooding season from happening.
How much of Egypt's electricity is hydroelectric?
It provides a tremendous amount of energy. Up to 40% of Egypt’s total electricity supply comes from the hydro-electric power that is generated by the Aswan High Dam. This means that the nation’s residents are receiving power from a source that is environmentally friendly, predictable in cost, and easy to maintain.
Is the Aswan Dam good?

By weighing the pros and cons of its existence, we can continue to evaluate if its present and future value will continue to outweigh its present and future cost.
What is the largest dam in the world?
The Aswan High Dam in Egypt is one of the largest dams in the world. It controls the floodwaters of the Nile River. Its hydroelectric plant supplies 15% of Egypt’s electricity. In addition, it has increased Egypt’s arable land since reservoir waters are used for irrigation.
What was the first dam in Egypt?
The first Aswan dam provided valuable irrigation during droughts but could not hold back the annual flood of the mighty Nile River. In the 1950s, Egyptian leader Gamal Abdel Nasser envisioned building a new dam across the Nile, one large enough to end flooding and bring electric power to every corner of Egypt.
How does the Aswan Dam affect Egypt?
The giant Aswan Dam covers a significant proportion of Egypt’s electricity needs: originally, it was forecast to cater to 50% of national demand. Today, the dam has 12 generators in operation, and generates annual hydroelectric output of 10,000 gigawatts. However, the barrage’s extensive environmental damage must not be overlooked. The main factor, one that was neither anticipated nor properly calculated for, is silt, which is retained by the weir. Since the dam was built, land has received reduced fertilization from this natural element, triggering a major agricultural crisis and consequent pollution from chemical fertilizers. The dam has also created greater water salinity, leading to the disappearance of many animal species. There is also some evidence of downstream erosion and worsening health problems: Lake Nasser’s irrigation canals and banks make an ideal habitat for Anopheles mosquito, a vector of malaria and other dangerous parasites.
When was the Aswan Dam built?
Work on the new Aswan Dam project began in 1952, the year that a Republican coup d’état dethroned King Faruq. Nasser rose to power, and was elected President of the Republic in 1956. In 1953, Egypt began diplomatic work on funding construction of this huge project. First the United States, then the United Kingdom agreed to finance dam construction, earmarking respectively 56 and 14 million dollars. This money was supplemented by funds guaranteed by the International Bank for Reconstruction and Development. All in all, some 270 million dollars was raised.
