The Egyptian geologist Abbas Sharaki explained that the area of the Renaissance Dam is made of hard rocks with many cracks, and therefore the leakage is expected in the dam lake area.
Sharaki said in an interview with RT: “There has been much talk in the recent period that there is a leak under the Renaissance Dam through satellite monitoring of an underground river from the bottom of the Renaissance Dam.”
He added: “The Renaissance Dam area is made up of hard rocks with many cracks as a result of the presence of the African groove that divides Ethiopia in two, and it is difficult to trace the groundwater by satellites that monitor the shape of the earth’s surface. This is done through field studies for more accurate data.”
He said: “The basaltic volcanic rocks that make up the volcanoes occupy most of the lands that are located in the Nile River basins within Ethiopia, and the highest hard rocks (igneous and metamorphic) and a few soft (sedimentary) rocks such as sandstone are located,” noting that “the Renaissance Dam area is low in relation to The Ethiopian plateau is a solid metamorphic rock, but it is cracked and suffers from a lot of decomposition by hot solutions that formed some economic minerals such as gold. Therefore, the Renaissance Dam lake will flood many mining areas.
He added: “The cracks are one of the reasons for the delay in the completion of the Renaissance Dam, as it is injected with concrete,” stressing that “water leakage through the cracks in the Renaissance Dam lake area is expected to be high, but it has not been measured so far.”
He said, “The leak here is not from under the dam body only, but through the cracks in the rocks surrounding the dam’s lake, which will reach an area of about 2,000 km2, and this does not mean that there is a river under the Renaissance Dam or caves, as some claim, because caves are formed only in rocks. Calcareous decomposition by groundwater, as is the case in Wadi Senour (Bani Suef) and Hercules Cave in Tangiers (Kingdom of Morocco), and what is in the area of the Renaissance Dam is many cracks and faults that can affect the safety of the dam, especially after it is filled with a full capacity of 74 billion m3 “.
He stressed that “the Ethiopian plateau has many geological problems, including the Renaissance Dam area, and the dam is exposed to many dangers, especially after filling, but this does not mean that we are running after any unscientific claim that weakens our credibility, even if it is upon us, but we follow what is issued by specialized experts. They have no political purpose.”
