Which was the only Indus site with an artificial brick dockyard?

Question

What word describes an open artificial water channel, in the form of a gravity chute, that leads water from a diversion dam or weir?

Answer 1

Lothal was the port city of Indus Valley Civilization. It was located at Saragwala, Gujarat. The dockyard was located away from the main current to avoid deposition of silt. It is speculated that Lothal engineers studied tidal movements, and their effects on brick-built structures, since the walls are of kiln-burnt bricks.
