(Bloomberg News) – Ethiopia’s plan to build Africa’s biggest hydropower dam on the main tributary of the Nile River must address concerns that there may be flaws in the design of its foundations, a group of international experts said.
They also called for further studies on what impact the 6,000-megawatt, $4.7 billion project may have on the downstream nations of Sudan and Egypt, the International Panel of Experts said in a report e-mailed to Bloomberg News and verified by Ethiopia’s Foreign Ministry.

Ethiopia is the source of 86 percent of the water that flows into the Nile, the world’s longest river that runs 4,160 miles through 11 countries from Burundi in the south to Egypt, where it empties into the Mediterranean Sea. Ethiopia has said it will take five to six years to fill the 74 billion cubic-meter (2.6 trillion cubic-feet) reservoir created by the dam.
