Imagine a place where the mighty Nile River, the lifeblood of Egypt, is tamed and transformed. That's precisely where you'll find the Aswan High Dam, a monumental feat of engineering nestled in the southern reaches of Egypt.
Specifically, this colossal structure is situated near the city of Aswan, a good 800 kilometers (about 500 miles) south of the bustling capital, Cairo. It's not just a dam; it's a comprehensive water management hub, designed to harness the Nile's power for a multitude of purposes – from irrigating vast farmlands and generating crucial electricity to controlling devastating floods, facilitating navigation, and even boosting tourism and fisheries.
The dam itself is a massive earth-fill structure with a clay core, standing an impressive 111 meters (364 feet) tall. It's strategically placed about 7 kilometers upstream from the older Aswan Dam, within the backwater area of the reservoir it created. This reservoir, known as Lake Nasser (or Nubia Lake in Sudan), is a truly awe-inspiring artificial lake, stretching over 500 kilometers and holding an immense volume of water. It's this vast expanse of water, held back by the dam, that allows for the regulation of the Nile's flow, a critical function in a region that experiences dramatic seasonal variations in water levels and occasional droughts or extreme floods.
The geographical coordinates place it around North Latitude 23°58'13" and East Longitude 32°52'45". The valley where the dam was built is about 500 meters wide at the riverbed, with slopes that gradually widen as they rise, reaching about 3600 meters wide at 100 meters above the river. The bedrock beneath the dam is a mix of metamorphic and igneous rocks, with sedimentary layers further down. This geological setting was crucial for the dam's stability and construction.
So, when you think of the Aswan High Dam, picture it firmly rooted in the arid landscape of Upper Egypt, a testament to human ingenuity on the banks of one of the world's most legendary rivers, a place where the Nile's ancient journey is now guided by modern ambition.
