wow stunning work and details there Becca the river walk is just stunning!!!

The ARS River Walk Base Set is now on STEX. Enjoy.

Still in development . . .

Is that a lock Becca? The doors and the sides look a little thin.  Thats a lot of water they are retaining.  Also, the doors need some way of opening, and somewhere to open them from.

Hi Becca! I agree with Shaun (Diggis) that the walls on the side are a bit thin. Even with the use of high strength concrete I think those walls can't handle the massive loads of the water in the lock. If you want to make the lock look realistic you should make the walls about three times as big

excellent work becca

[RebaLynnTS]

Thank you all for the comments and suggestions, I have taken them all into account with the redesign. I did want to mention that the doors are the type that are lowered straight down, and then back up. It was the best way to do a variable width lock. Eventually, there will be a second set with out walk ways that can be mixed and matched with the these, to build all kinds of combination's.

Do you have some images of this style?  It's not one I am familiar with (albiet I'm no expert, but living in London gives plenty of opportunity to see locks in action and I was thinking of modelling one) and I'm not sure how it would work as the water spilling over the top of the door would take the boat with it.

I would also be interested in seeing a pictur of a lock of this type. We used to have a boat on the canals in England I never saw one like this.

[RebaLynnTS]

This is where I got the idea from, however I have not been able to find a real life picture so far.

The water pressure acting on the bottom of the canal walls and lock gates is really huge.
Take a look at the side of the canal in your reference picture (under the word "ladder"), and you'll see how much wider it becomes further down.

Looking at your raised ARS I'd say the sides are far too narrow. They need to be quite a lot wider, especially further down.
The locks need to be of really strong framework construction (often they have steel plates only on one side).
The taller they are, the stronger the need to be...

Here's a picture from the Panama Canal. The thickness of this lock gate is some 8-10 ft:



In order to ease the closing and opening, the lock gate halves most often close like that, in a wedge.
In this case the hydraulic cylinders are pushing the gate halves towards each other.
Otherwise it would be a lot more difficult to get them to close watertight.

The lock gates in your picture don't seem to be any wider that the light poles...
I'd say they should be at least as wide as the walkways.
And the bottom of the canal sides should be even wider (unless they are dug into the ground)...

[RebaLynnTS]

The side walls of the raised river are 4 meters thick, just like the real thing. When I designed the project I used measurements from as many real world sources as I could find. As far as the Lock goes, I am doing a big remodel. I hope to have a new picture in a day or two. Sometimes I get in too much of a rush, and don't properly think things through, which, by the way, is why I am grateful for all the input.

I was already expecting that. In my hometown we have a lock that functions that way. Here some pictures. If you want some more pictures and details just ask. There's a bridge next to the lock so I don't mind taking some pictures of the structure

Here some shots I found on google. The lock is called the Beatrixsluis and is located in the city of Nieuwegein








And a detail of a door

[Diggis]

Correct me if I'm wrong Merijn (It has been known to happen, once.  I thought I was wrong, but I was mistaken  )  but those gates lift UP to let the barge through, not recede into the ground.  Going up allows the water to come out from the bottom of the lock meaning there is no flow on the top leaving the boat/barge to slowly lower without running over the top. 

[tag_one]

^^ Indeed. I thought Becca was planning to make that, I should had to read her post more carefully 
Reading has never been my strongest point

So to get it right; the door disappears in the ARS lock and than the barge goes trough it? Sounds a bit like that project in Venice to keep floodwater out of the city.

It is very much like that.

Diggis: If the water level is raised or lowered to the same height as that on the other side of the door, before the door is opened, then there should not be any flow when the doors are lowered (just some back wash, but that comes from both sides, and has little to no effect on the barge).

I chose this design (for this lock) because I wanted it to be variable width, and that worked best. On another note, I do plan to make other designs, but they will all be fixed width (1 or 2 tiles wide)

Correct, sorry I thought you were intending the water to spill over the top when the doors were lowered.  The locks I've seen have a door at the bottom of the gates to let the water through from the base into the next section.

[RebaLynnTS]

Well, I have learned one thing from all this. I will be sure to but in an explanation of how the lock works when I do the read me file

NOTICE: All ARS files have been updated. Currently the updated versions are only on the PLEX. I will be uploading them to the STEX no later than tomorrow night. Once done both sites will be current. ALL ARS Updates and new lots are now on STEX.

NO reploping will be needed.

Now I have a question. How can I set up one of my lots to supply income to the city, based on the size of it's population?

(I'll be researching this, and if I find the answer, will be sure to let you know.)

[RebaLynnTS]

The first set of the MSS has been revised and re-released on the STEX.
