A newly discovered branch of the Nile River, named the ‘Ahramat,’ played a crucial role in the construction of 31 ancient Egyptian pyramids, including the Great Pyramid of Giza. Researchers utilized radar satellite imagery and other techniques to identify and map the remnants of the Ahramat branch, which was located near the pyramid sites and served as a waterway for transporting materials. The study sheds light on the logistical challenges faced by the ancient Egyptians and their innovative solutions for transporting heavy materials.
