The Nile Tripartite Committee, composed of experts drawn from Ethiopia, Egypt and Sudan, and four international experts officially known as International Panel of Experts (IPoE), made a second visit on Monday to the construction site of the Grand Ethiopian Renaissance Dam to review the impact of the dam.
Since Ethiopia launched the dam in April 2011, there was concern, especially from Egypt, which fears that the dam will reduce the flow of water to its territory.
The dam, being built over the Nile River is Africa's biggest dam, expected to generate 6,000 megawatts of power.
The committee is visiting the dam at Ethiopia's invitation "as good will gesture to build trust among (Nile) riparian states".
The experts committee, which started its activities in Addis Ababa, Ethiopia last May paid its first visit to the construction site of the dam on 15 May. It also held its first meeting on 6 June 2012 in Cairo.
The committee is expected to present its findings in nine months to the highest authorities of Sudan, Ethiopia and Egypt.
"Ethiopia has conducted numerous studies on the project, which unequivocally affirmed the benefits of the project to downstream countries," the Ethiopian Ministry of Foreign Affairs stated.
Ethiopia says the dam, being built with a $5 billion self-funded investment, will not affect the Nile River's water flow.
"The project will have the benefit of preventing floods and siltation in downstream countries for the flow of the water will be regulated throughout the year," Ethiopia says.
"It will also have added benefit of reducing evaporation as it is being built in less humid gorge."
The project is expected to start power production in two years and is expected to be completed by 2015.
