USA HISTORY

Detailed explanation-1: -The impressive aqueduct system of the Incan empire functioned to irrigate agricultural terraces and bring fresh drinking water into the cities. The aqueducts, often build on the sides of mountains, collected water from the mountains for distribution elsewhere. The same aqueducts are still used extensively today.

Detailed explanation-2: -Inca and Aztec Aqueducts The Inca built an elaborate system of aqueducts, some of cut stone, which wound through hills and valleys to bring water from the mountains. One of the Inca aqueducts leading from the highlands down to the sea was 360 miles (579 kilometers) long and 13 feet (4 meters) deep.

Detailed explanation-3: -By cutting the canals out of one stone, lining canals with rock, and filling joints with clay, the Inca were able to reduce water loss due to seepage. The water from this stream provided water for sixteen fountains, lending an additional visual and auditory aspect to life in Machu Picchu.

Detailed explanation-4: -Yet the Incas, and the civilizations before them, coaxed harvests from the Andes’ sharp slopes and intermittent waterways. They developed resilient breeds of crops such as potatoes, quinoa and corn. They built cisterns and irrigation canals that snaked and angled down and around the mountains.
