Please read the whole description below and check out the images above before you comment with any problems. Thanks!

Welcome to Network Rivers, a set of networks designed to direct water through your maps and to look like realistic rivers.

I have always found creating rivers with the landscaping tools very difficult and the final results never look like real rivers. This is why I came up with the Network Rivers idea and why I've spent a long time messing around trying to make them usable and effective. The river networks can be tricky to use effectively but with trial-and-error can work well and look fantastic.

This pack has a 'City River' theme with concrete banks and mud flats that show when water levels drop recreating the rivers found in towns or cities. The rivers are found in the Water Structures menu.

What's in this Pack?
This pack contains ten rivers varying in width from 48 metres to 160 metres.

In addition, the rivers contain ferry routes in both directions.

How to lay down the rivers
(There are images above relating to the sections below.)

I highly recommend watching the tutorials and, at the very least, looking at the instructions for the 'Green Valley' or 'Rocky Mountain' river packs. The technique for these rivers can be different but they can still be used as an extension of the other packs.

1. Prepare the ground: Once you've identified the course of your river check that the source will be higher than the estuary. It's better if the slope is minimal for this pack as slow moving water looks more realistic in wide rivers. Then use the 'Slope Terrain' tool to make an even slope from top to bottom following the route of the river, including all the curves and bends.

2. Lay the river: Next it's time to plop the river along the ground you've sloped. I recommend using the 'Freeform' network tool to create realistic curves as the river descends.

3. Smooth the slope: Use the Move It 'Align Slope' tool to ensure that all the river nodes are gradually descending.

4. Correct the terrain: Use the 'Soften Terrain' landscaping tool to smooth out any sections that may have appeared after aligning the slope. I advise using this tool to make sure surrounding ground is not below the river height otherwise water may 'leak' out.

5. Add the water: Use the 'Water Tool' to create a water source set at the capacity of 0.01 and lower the water level quite low.

6. Control the flow: Once you get the flow at the top correct you will notice that the flow may be less as the river continues. The best way to control this is to add additional water sources where the flow needs a 'boost'. By typing in the flow setting between 0.001 and 0.005 (rather than using the slider) the flow can be subtly controlled.

7. Joining rivers: It can be difficult to join two rivers as the close nodes can get in each others way. If you delete the indicated nodes with Elektrix's Road Tools mod and lay the connection from the target river to the inlet it should be possible. Also delete the last-but-one node on the inlet to make the connection cleaner.

8. Wider river errors: Laying down the widest rivers (128m, 144m and 160m) can be tricky as adding to them often creates a "Too close to another canal!" error warning. If you use Elektrix's Road Tools mod to delete the last-but-one node you should be able to add more river. This is not an issue that I can resolve and, as far as I can tell, is caused by the nodes being relatively close to each other and the river being so wide. When low down and viewing from a narrow angle elements of the widest rivers may disappear. This visual glitch is a game issue.

9. Ferries: For ferries to work correctly the water level must be high enough. If a small amount of mud flat is showing then all should be OK but at lower water levels the ferries may stop until the water rises.

Please note that getting the flow right is more of an art than a science.

This pack contains:
1. NR City River 48m
2. NR City River 56m
3. NR City River 64m
4. NR City River 72m
5. NR City River 80m
6. NR City River 96m
7. NR City River 112m
8. NR City River 128m
9. NR City River 144m
10. NR City River 160m

River texture: 1024 x 1024
LOD: 256 x 256

I have aimed to keep the file sizes as small as possible. All the rivers share textures allowing the Loading Screen Mod to share them in game and therefore reducing the load on your computer.

All files in this pack use the same naming structure to speed up 'Find It' searches. All elements start with NR followed by the asset name.

I would like to thank podpodda for testing these rivers, giving such valuable feedback and providing such wonderful screenshots for the artwork.

Please try this pack out and let me know, in the comments below, if you have any problems or suggestions. I have endeavoured to make these rivers as useable and effective as possible but there may be errors and problems that need to be addressed.


If you really, really like my assets please consider making a donation. I'm unable to work because of ill health and do this because I love the positive feedback I get from so many people.

I have a question that is similar to that of steel_ratt. I am building a map in the map editor to build my city on and want to add several rivers using these assets, but like steel_ratt can't seem to get the water into the river. I have made a recording so you can see what I'm doing.

In my game the asset appears to look slightly different from how they look in the tutorial videos. It's almost as if they have two rims/banks instead of one. In the tutorial video's the river seems to blend into the terrain more.

A stretch, but can you add 32m- and 40m-wide ones?

Do these work in the map editor? I'm having a devil of a time making them work. It seems to be quite easy when playing the game. (I'm not talking about the lack of curving tools... move-it can take care of that. The rivers just don't seem to contain ANY flow without overflowing or being dry.)

Nice mod. Could you maybe add a new type of city rivers in the future, namely, ones with concrete banks sloped flatter than 45 degrees?

@Macwelshman .. This is awesome...thanks for all your river networks. Did you ever think of doing a L.A. River network? Keep up the great work...

@Macwelshman - what is the road mod you use for those beautiful cobblestones (11th pic with sailboat at top)

@IanLai None taken.

35 meter is for ship travel , so sounds reasonable . the canals also use for sewage . the water dump out can be large amount when i was 10k population . i did get flooding if i use the same canal for all sewage facility ,even the deepest canal

don't worry , i am not going to down vote people hard work just because i don't use it
just my personal feeling about the canal no offense

@IanLai The vanilla canals are ridiculously deep (35 metres). These rivers are based on realism.
Macwelshman  [author] Feb 12, 2020 @ 7:25am 
@IanLai The depth of the rivers is 7 metres in the centre and 3.5 metres on the banks. The side walls sit 0.5 metre above ground level. If the water level covers the mud banks by a metre then the centre will be 4.5 metres in depth. I don't think that is unreasonable.
