From ancient times to modern times, civilizations build dams of varying designs to divert water flow, irrigate lands and generate power supply. There is one in particular which has the reputation for fascinating historians and engineers that come across it. It is the 2000-year-old Grand Anicut...
At first glance, you may confuse a barrage and a dam. Both are built across large bodies of water to control the water level. However, they have very different construction processes and uses. We’ve put together some fast facts about the difference between a dam...
