Questions this course answers

What is the main purpose of a canal lock?

A lock changes the chamber's water level so a floating vessel can pass an elevation difference.

Why are water levels equalized before opening a gate?

A large level difference creates a strong pressure load that can make opening unsafe.

What makes the boat rise during filling?

The floating boat follows the rising water surface while remaining buoyant.

How does a conventional lock move water?

Water flows between pools because of their elevation difference; pumps are usually unnecessary.

What happens in a staircase of locks?

Multiple lock chambers divide a large climb or descent into manageable steps.
