Evaporation/Soil Absorb

[Zhou]

[Missing note added on 2023-12-05] Soil now absorbs water much faster from small water bodies.

Was gone Complain about this being a bug, but you added it to the patch notes.
I can understand the change because you want to Remove the Fluid dump trick.

However water just dissapears at the speed of light.
Before Update Roughly 22 Days.

1 x 1. - Within ~2.5 days
1 x 20 - Within 4 Days
3 x 3 - 10 days (almost on the dot)
3 x 20 - Within 17 Days
5 x 5 - Within 15 Days
5 x 20 - Within 19 Days (Almost same time as 9 x 9)
7 x 7 - 17 Days
7 x 20 - Within 20 Days
9 x 9 - Within 19 Days (Almost same time as 5 x 20)
9 x 20 - Within 20.5 Days
11 x 11 - Within 20 Days
11 x 20 - 21 Days

I did some more testing.
And if the canal isn't straight the same 3x20 But shaped like a W its gone in 9.5 days. https://i.gyazo.com/aafedb40dcde292d0a87c10ad039fb92.png

Depth doesnt seem to matter. a 3x3 1 dept or 2 dept. Every layer evaporated in 10 days.

I don't understand why theres such a big diference between 2 Bodies of water both 60 tiles. One is Sqaure and 1 isn't. and since most rivers have curve's they dissappear fast.

I started testing this because on the map i was playing before the last patch my system wouldn't run dry. i noticed my Consumption went up. and the River who on a 30day drought on Hard mode hardly ran out. Was almost dry.

Heres my final Opinion.
I think the nerf is a bit to big. The irrigation range combined with the Soil absorb.
The Fluid dump trick went from 1 Block of water(5 water) in 22 days.
To 9 Blocks of water in 10 days. (45water).
in the same 22 days you now need 99 water, making this 20x more water being consumed. Combine that together with Rivers are drying up faster because of the shape.
So less water can be pumped out of rivers.

I'll have to start a new map to see how deadly it is early game.

i'm glad someone can do the maths i just know in just a few days entire chunks of water are drying up and on my hard play through, i'm just not getting enough water to refill my reservoirs and they aren't much more than halfway now and decreasing. which is a losing game,

This was a stupid change. Now the fluid dump is completely useless.
Edit: With a recent mod, this is now not so much of an issue for me.
See my post below. And maybe not such a 'stupid' change but one I don't care for so much.

very good change in principle, this has certainly fixed water management being trivial. i'm sure it'll be fine with a couple balance tweaks here and there.

haven't played at 30 day drought yet but i have had the river (on diorama) dry up quite a lot in early game ~5-7 day droughts even with pumps paused which isn't unmanageable by any means but also doesn't quite feel intended either.

(kinda looks like the water at the start of the droughts is already lower than 0.5 from dams.)

I'm not sure if this is the same bug or a different one but I've got quite a few hours on this save. When I loaded up today my fluid dumps suddenly stopped working properly.

Now they only hydrate about two squares from the fluid dump instead of spreading out and hydrating the ground in the 15 block radius or whatever is normal.

I've tried several other saves and they all have the same issue.

My experiment is using mechanical fluid pump and check height
Since pump max height is 0.9, there will be slightly different

After 1 day fluid height => last day
1x1: 0.47 => 2.1 day
1x9: 0.61 => 3.1 day
2x2: 0.69 => 4.3 day
2x2+1x5: 0.66 => 3.8 day
3x3: 0.8 => 9 day
4x4: 0.82 => 11.2 day
5x5: 0.83 => 12.9 day
6x6: 0.84 => 15 day

so
1. 1 tile wide water canal will be absorb more even you have larger water pond
2. 3x3 seems best for reduce absorption rate and land efficiency

honestly, I like the extra challenge. hard mode wasn't actually that hard with the old water dumps. And it makes sense that water disappears faster giving that its being used to water trees and crops and such.

I think they are going to bring back some sort of irrigation tower, and for both factions, soon.

I think the speed of absorption/evaporation is also connected to how much soil surface area is touching the water tiles. This would explain why squares are the most efficient shapes for water reservoirs.

This would be quite unfortunate for me since I don't like square reservoirs, lol

[jamiechi]

TBMPL_WaterSourceControl mod allows one to change this back or to something else if you want.

Need update check?

If we cover a water reserve made with a dam with an impermeable surface, does this stop evaporation?

It does not.
