Consider the following statements regarding the hydraulic layout of the dockyard discovered at Lothal:
1. The basin was strategically connected via an inlet channel to the ancient flow of the Bhogavo River, allowing ships to enter during high tides.
2. The dockyard featured a specialized vertical sluice-gate system built of baked bricks to regulate water levels and keep ships afloat during low tides.
Which of the statements given above is/are correct?

Question

Accepted Answer

Both statements are correct. Lothal's dockyard is an engineering marvel. It is a trapezoidal basin made of kilned bricks. The inlet channel utilized tidal locks to safely float heavy cargo vessels inside, while an adjustable spillway functioned as a sluice gate to drain excess silt and lock operational water columns.
