I cannot for the life of me understand how they work on a canal for example. Please dumb it down as much as possible
In: Engineering
water always flows downhill (unless you pump it back up).
A lock is two sets of doors that either block or allow water flow from the higher side to the lower side. by closing the lower doors, the water level inside the lock rises (with any boats inside) until it meets the water level of the higher side.
to lower the water level inside the lock, a smaller drain opens to allow water out until level with the lower side.
Practical engineering has a great and simple video (with models!) [https://www.youtube.com/watch?v=SBvclVcesEE](https://www.youtube.com/watch?v=SBvclVcesEE)
