What are the two problems the Aswan Dam has created?
The loss of sediments has created coastline erosion. The Aswan Dam, because it prevents the Nile River from leaving sediments, has increased the pace of coastline erosion that occurs around the Nile Delta. It is estimated that the erosion proceeds at over 550 feet every year. 5. The Aswan Dam has created an increase of soil salinity.

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 problems with the Aswan High Dam?
Another detriment to humans has been the spread of the disease schistosomiasis by snails that live in the irrigation system created by the dam. The reduction of waterborne nutrients flowing into the Mediterranean is suspected to be the cause of a decline in anchovy populations in the eastern Mediterranean.

What would happen if the Aswan Dam broke?
What if the dam were destroyed, leaving Lake Nasser to rush downstream? The answer is that a tidal wave of such magnitude would be created that Egypt would essentially cease to exist as a country. Tens of millions of people would be killed, and untold material damage would be created.
Do you think Aswan Dam helped hurt 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.

More food, hydroelectric power, and flood control outweigh the problems, and the relocation of the Nubians, the expense of artificial fertilizers and field drains, and the increased incidence of diseases of outweigh the benefits.
What could happen to the Aswan High Dam and Lake Nasser if the water continues to increase?
"This is a rock fill dam, not concrete like Hoover Dam, and water going over the top could erode the earth and rock. You can't let that happen." With Ethiopia, source of the Blue Nile, reporting its heaviest rains in 50 years, the level of Lake Nasser is likely to climb higher.
What are the plusses of the Egyptian dam?
Here are some of the plusses I can identify. The dam will control, and humans can manage the controlled flooding to maximize the benefits to the Egyptian people. It will bring the desperately needed electricity they need to move their economy, and all of the blessings that come with it, along an industrialization path. Two very big pluses.
How does a dam affect the Delta?
The down side is that the dam blocks fertile silt from flowing down river which adversely affects the fertility of the River bank farming, the blocked silt builds in the bottom of the dam lake itself and also back builds up far upriver and the delta suffers from erosion which for lack of silt build up the silt on Delta is wasting away into the ocean.
Why did the Russians build the Aswam?
Yet they served their purpose in years gone by such as bringing water to the deserts of of the world. As we progress throug time Dam water retention levels are ebbing lower and lower to te point where they will no longer be necessary. This is because water as a resourse is drying up worldwide and rivers lakes and seas are receding. So Aswam built with all good intentions by the Russians for Nassar has achieved its purpose in regulating the Nile annual flooding that once plagued lower Egypt. Now it is just a matter of time as Answam will fail to deliver its original mandate as water gets scarcer and scarcer worldwide?

What is the cause of the erosion of the Nile Delta?
That lack of silt has caused the Nile Delta to experience erosion and shrinkage instead of replenishment and growth. As a result, farmland is being lost, and shorelines are receding.
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?

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?
There have been many good things that have come out of the building of the Aswan High Dam, but there have been some consequences to its creation as well. 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 effect of the Nile Delta dam?
Nile Delta Erosion. Building the dam has also led to the reduction of sediment and silt supply due to the occurrence of floods every year. Because of this, there has been erosions experienced at the Nile Delta which reduced the land area. At the same time, the overflowing of the dam has brought the trapped silt to fall into the reservoir.
What is the name of the dam that Egypt built in 1970?

How have droughts and famines been prevented?
Drought and famine have been prevented because they are able to use the hectares of land as agricultural land instead of desert. 2. Hydroelectric Power. Hydroelectric energy is an excellent source of electricity from dams. Even other dams around the world are able to supply water to agricultural areas.
Why is the Nile flooding important?
The yearly flooding of the Nile was crucial to water crops in farmlands. However, the different level of flooding has not been good for agriculture. In this, the water levels that are high has destroyed the crops while low water levels has also caused famine and drought.
What are the pros and cons of the Aswan Dam?

What were the effects of the Nile dam?
1. There was an effect in the fishing, agricultural and red-brick construction industries.#N#The construction of the dam led to a decline in the fishing industry. Since it was built, the nutrients from the river that used to flow to the sea were trapped, leaving lesser food for aquatic life. Also, the absence of flooding in Upper Egypt, the minerals that serve as fertilizers to farms were gone while sediment deposits along Nile which are used to make red bricks have been affected.
How did the Nile Delta affect the water supply?
As a result, reducing land area. Also, when the dam overflows, the trapped silt falls on the reservoir, reducing the area and its capacity to supply water and electric ity.
Was the Aswan Dam built with good intentions?
Aswan Dam was built with good intentions and its construction has indeed become instrumental in the industrialization of Egypt. However, just like in other new developments and changes, there are also consequences. It is just a matter of ensuring the pros outweigh the cons.

This is because of the dam’s complete control of the Nile’s annual flooding. Much of the flood and its load of rich fertilizing silt is now impounded in reservoirs and canals; the silt is thus no longer deposited by the Nile’s rising waters on farmlands.
