The Panama Canal is amazing. If you ever get the chance to go, they have a great museum at Miraflores. I was lucky enough to do a training course at the Canal Authority Admin Building - it is both gorgeous and full of history. The canal pilots are also awesome. They have to train with scale model ships as well as simulators and take their jobs EXTREMELY seriously. I would have loved to speak with some of the canal operators too, but we were mostly focused on navigation. Thanks for filling in some of the gaps!

And then for small ship, high displacement locks, a gravity hydraulic lift lock is even more efficient. The Trent-Severn waterway in Ontario Canada has two of these lift locks, only wasting about a foot of water each trip. It works by having a hydraulic system in the shape of an ‘H’ with a stop valve in the middle with two piston rams on either side holding up a basin each. The water depth on top is greater (about a foot or so) than the bottom so when in it's open position, one basin is gaining water and the other is losing water. When it's time to switch, the valve in the center opens and the side on top, due to it having more weight from that extra foot of water, let's gravity take control. This goes until it reaches the bottom and the valve is closed. At this point, both basins open up, restarting the cycle, now on opposing rams.

The struggles of the workforce and deaths from Yellow fever and eventually the US Government getting the army to build it in the form it is today. If you can can find it it's well worth a watch.

I've lived for over five years on the English canals and locks are a major feature. My favourite is the Caen Hill flight of 16 locks at Devizes in Wiltshire. Each lock has a large side pound to enable it to work. The canal between locks is a pound anyway, but close together locks need extra help, and Caen Hill also has a pumping station at the bottom to assist at drier times.

Something else interesting to note, I learned when transiting the Panama Canal, when entering a lock, especially when you are panamax width and close to panamax depth, the propeller doesn't so much push you into the lock, as it acts as pump, pulling the water OUT of the lock, and allowing the ship to take up the volume displaced inside the lock. We would be at 1/2 ahead maneuvering, and be making about 1/2 of our Dead Slow Ahead speed as we entered. The other thing I learned that trip, if you don't keep an eye on the riding gang, they will flush chicken bones down the toilets and royally mess up the MSD tank!

In this email country, we have approximately 4,200 miles of inland waterways. A large majority of which are canals. I spent six years living in a 62’ narrowboat. Considering that many canals have to cross mountainous and hilly parts of the country, this involves the use of many locks, however the canals often bore through hills in tunnels or use othe means to effect a transit from one level to another. The Anderson Boat lift is one, there used to be an inclined pain at Foxton and in Scotland there is an ingenious counter-balanced wheel at Falkirk. Locks are also used on navigational rivers, which hol water back to create weirs, accompanying them to effect a change of water level.in a flowing river.

The graphics with your explanation made so much more sense. Very educational, thanks.

I have some experience in marine engineering, though not with locks. In any case, you can see the satellite imagery of the Panama Canal locks and other lock systems throughout the world that have high bidirectional traffic, particularly crossing inland. The north end of Panama is particularly clear that the two sets are for bidirectional traffic. In general, these situations tend to use two sets for each direction from what I can tell. Practically speaking, I imagine there would be water savings given having the two sets could continue that sequential set of ships passing through that allows the multiple-locks and the water-saving basin setup to keep the water savings going as demonstrated in the animations. Reversing traffic direction would likely require draining much of that water savings built up. This seems like one of those scenarios where I am sure the experts considered traffic consistency and a number of other factors put into a equation set or design spreadsheet of some sort. How much they save by having two sets, I couldn't say.

The St. Lawrence Seaway (Great lakes and St. Lawrence River) only has a single lock going around the Moses-Sounders Dam (which has 2 observation points, covid closed the one at the visitor center). Being on such a large river with relatively low traffic flows i imagine then can plan traffic to raise a ship and then lower a ship with the same water, effectively halving water usage on top of any other wayer saving methods employed. I also suspect that the whole system together counts as a ladder lock, just with many miles of river / lake / reservoir between them. (Technically we call the reservoir Lake St. Lawrence and I'm kinda fuzzy on where it ends and Lake Ontario begins especially since the Thousand Islands looks like a reverse river delta (they are made of rock though))

Small correction, the angle of the gates is to turn them from more of a horizontal beam into a compressive arch, but they don't prevent buckling. In fact, buckling is something that happens specifically due to compression. The compressive arch just makes for a much easier mechanical design. But even then, the gates are usually prismatic (rectangular) while the water pressure increases with depth. This means there's a rotation applied to the gate that makes everything complex again.
