What is the major problem with the Aswan High Dam?

Despite its successes, the Aswan High Dam has produced several negative side effects. Most costly is the gradual decrease in the fertility of agricultural lands in the Nile delta, which used to benefit from the millions of tons of silt deposited annually by the Nile floods.

How has the Aswan High Dam hurt Egypt?

The negative effects include increasing soil salinity, changes in the water table, excessive downstream water plant growth, and diseases such as schistosomiasis and other intestinal parasites, and the social impact on the Nubians, whose homeland was flooded.

What would happen if the Aswan Dam burst?

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.
