How do I get water flow on level flat map?

[MarkJohnson]

I am using the default flat map in map editor. I place a river on the border of the edge of the 25 tiles from top to bottom and chose the bottom corner as my starting tile.

I place water spawners at every tile intersection along the edge (6 spawners total) but the river doesn't flow and stays stagnant.

Is there an easy way to get water flowing?

set the water spawners capacity (height) different. Water will flow from a higher spawner to a lower one; spawners will act as a supply or drain in an attempt to get water to their height.

I'm pretty sure my sea bed was flat as it's a map I created myself. I think the water source flow setting needs to be fairly strong and the flow direction was determined by the sea level height the spawners are. So flow is from high to low.

I tried that already. It seems to change them all at once though so they all end up at the same height and flow. I think I started at 70 and gradually went down to 50 a few at a time.

Then I reset to sea level and they just seem to bounce back and forth to each other going nowhere.

Firstly, rivers are not flat.
So, I don't know what it is you're trying to build. Anyway, if you insist on building a flat channel and you want to use water spawners as your driving force, then you need a closed end for the source and open at the other. Use a full capacity spawner, depending on the width and depth of the channel.
The rest of the spawners you mention using, I assume are meant to be volume/surface level maintainers. That is their function. Do not expect them to be an impelling force. They only maintain the surface level. It is is also important to make sure that these should be set to very low capacity, around 0.10 or so.

That's what I ended up doing finally. I first took out all of the spawners except the edge one to force the flow. I ended up damming up that end as well to help force it down. I put the spawner at a full 1.0 max strength. I didn't know if that would feed all of the water pumps as the river got lower and lower as it reached the other side of the map.

I then added spawners, but they were messing with the flow and ended up putting .10 spawn points at every tile intersection. I'm not sure they are enough, but the flow is really fast like I wanted it.

How high should the flow be for a bunch of clumped together water pumps? Maybe I should just make it with two spawners per tile at .10 strength?

Only thing left to do it test I guess. Maybe I'll download extra landscaping tools and test on an existing city and see how well if flows.

p.s. how do I tell the strength of the spawners? I hover over them and they just show water level. right clicks removes them, left click places them.

That's your answer ;)

[MarkJohnson]

Well, I couldn't get anything out of extra landscaping tools.

I decided to just build on my map and see what happens. Well, water stops flowing from intake and sewage output. The spawners seem to stop the flow upstream as spawner not only spawns water, but it drains it as well. So it keeps the poo water stationary.

But downstream, the water flows very well and fast.

I tried removing all spawners except the top one and it pulls up the sewage water as it seems to try and level it. The sewage drain is 3 tiles away.

I just can't figure this flow out.

EDIT:

Here's the saved game if anyone wants to take a shot at it.

All I have done is raise the level of the water spawner near the water towers and lowered the level of water near the sewage.
I suspect flow strength could be improved by using bigger capacity water spawners, but I couldn't buy the tile for the other half of the river to try it out.

Rockfield given a river.
The existing 'river' on this map was no river at all. It was simply a flat broad channel from one end of the map to the other. Given the volume of water, it is a little unreasonable to expect one full capacity water spawner at the source to push it all to the other end of the map. I do not say push it downstream, because there is no downward.
So, in order to make this a river, I used the ELT mod's slope tool to create a gradient from the source, set to around 25m, all the way to the 0m at the exit point. This now makes it a river. The assistance of gravity helps the water flow downstream and is necessary in order to achieve this.
I also removed all of the supplementary water spawners so that I could better measure the efficiency of the source and let it run for enough time for the water system to settle in.
As you can see, it now flows strongly downstream as a river of this size should. The sewage outflow is easily being carried away downstream.

I forgot to add the water pumps back in the river so you could see my issue better.

@mbutton. I tried that method before a few times with different variations without success.

@Grap. The water flow was good at the starting tile, but was pretty well empty by the time it reached the exit on the other end of the map.

I forgot I set the sea level to 1m. I put it up to spawner level, but flow was horrid and just sucked up the sewage in no time. with or without spawners.

I never tried the slope tool. I thought I had to step it down manually. Maybe that will help getting past the spawners. It seems the pumps and sewage alter the flow too much and stop it completely.

I tried to look at other maps , but I can't find any way to measure water spawner's strength or level. It seems odd it's not in here somewhere. Maybe I just don't know where it's located.

Maybe I'll check out skyestorme's videos again. Maybe I missed something.

Here's the new save with water pumps instead of water towers.

I just tried your new map (with water towers), did exactly the same as before and again have a flow. The sewage has cleared all the way back to the bridge. It took maybe a couple of minutes (on x3 speed) before the arrows started appearing, but then the water cleared.

Did I post the wrong city? :(

I thought I posted the one with water pumps.

I just tried with the sloping and it seems to work a little better, (with no water spawners), but the river still reverses flow with only 4 water pumps.

I gotta run, going on Sunday family early dinner in an hour, so I have to get ready.

Thanks for your guys' help.

Sorry, my typo. Yes it was the map that had water pumps:
