Water erodes the landscape creating streams and waterfalls producing gravel, sand, clay, and moss
Water escapes from lakes and aquifers. Dirt and sand wash away to deepen stream beds and cut river banks. Find Forest brooks and Mountain creeks in your explorations. Pass through a dry Desert valley one day and find it flooded the next. Supports Forge for 1.12+ and Fabric for 1.14+.
Erosion in Minecraft, just like real life, is a slow process. You must wait see to the effects or increase the random tick speed.
Goals
- Implement Water Erosion as though it were a default Minecraft feature to make worlds more dynamic.
- Provide a renewable source of Coarse Dirt, Sand, and Clay fitting into the stock game mechanics.
- Avoid breaking stock existing game play.
Features/Rules
- Water flowing over an edge erodes the block below.
- Water flowing into a block "saturates", then dissolves the "wall." Turns towards the closest air space.
- Water flow ends "saturate", then dissolve the block below to potentially continue the flow downhill.
- Water Sources dissolve blocks to the side in the direction of air spaces.
- Erodable blocks include sand, gravel, clay, farmland, dirt, grass, and, rarely, cobblestone.
- Erodable blocks have differing resistances to erosion depending on their density, but all erode over time.
- Blocks decay during erosion to weaker blocks before disappearing.
- Blocks decay upstream in stream beds.
- Cobblestone and Stone Bricks grow moss near water.
- Enable/disable Farmland erosion via config file (Forge for 1.14+ only for now)
Decay hierarchy:
- Cobblestone -> Mossy Cobblestone -> Gravel
- Stone Bricks -> Mossy Stone Bricks -> Gravel
- Grass Path -> Grass -> Dirt -> Coarse Dirt -> Gravel
- Gravel -> Sand -> Clay(rarely) -> Air/Water.

Media
Installation
Fabric versions
Download the current release water-erosion-x.x.x-fabric-x.x.x.jar and add to your installation.
Forge versions
The Forge version for Minecraft 1.12.2 is a Coremod containing an embedded copy of the org.spongepowered.asm.launch.MixinTweaker library. It does NOT require MixinBootstrap.
The Forge versions for Minecraft 1.14.4+ require MixinBootstrap. Download the current release water-erosion-x.x.x-forge-x.x.x.jar, then download the MixinBootstrap-1.0.0.jar. Put both files in your MinecraftForge Mod folder.
TODO features
- Optionally drop items of eroded blocks
- Configurable Erosion odds and types - Slow, Medium(default), Fast, Custom - Version 1.1.2 for Forge 1.14+ adds a config file to enable/disable Farmland erosion. 1.2.0 will contain more options.
Technical Notes
This "core mod" adds code to the Water block randomTick() functions using the Mixin framework. randomTick() is only called by the Minecraft runtime for a 128 block radius around the player, so the odds of erosion occurring are set fairly high.
Tutorial
Sand can be generated from gravel with a simple machine
Test Areas
Create each world, teleport to the specified location, and, optionally, change the randomTickSpeed setting to speed up the process. Note: You must wait upwards of 30 real minutes to see the effects if you do not change the randomTickSpeed, such as in a survival world.

does the most recent version work with fabric 1.15.2?
In reply to explodingdigger:
There six supported combinations of Minecraft version and Mod System: Three forge, three fabric. Both water-erosion-1.15.2-fabric-1.0.1.jar and water-erosion-1.15.2-fabric-1.1.0-alpha3.jar will work for Fabric 1.15.2. There will be one more alpha before the release of 1.1.0, functionality is subject to change.
There are a couple of behaviours I'd like to see.
Water deposits erroded material where it meets still water. River deltas form.
Water weakens nearby fragile blocks like sand, gravel and dirt causing them to slump into any adjacent voids. You may be able to piggyback the hydration code for farmland for this rather than everything collapsing immediately.
In reply to DrFraudAu:
> Water deposits erroded material where it meets still water. River deltas form.
I've been thinking about river deltas since I was first designing this mod. I don't have a good idea about how to make them without significant CPU costs. Best idea right now is eroded blocks dropping items, letting the item movement code handle their location, then, on despawn, converting items back into blocks. Everything else I think of requires an efficient block to block path search down the flow to find the static water. Do you have any better ideas about how this could work?
> Water weakens nearby fragile blocks like sand, gravel and dirt causing them to slump into any adjacent voids. You may be able to piggyback the hydration code for farmland for this rather than everything collapsing immediately.
This is effectively what already happens when source blocks break to the side when a void is found in that direction. Additionally, I plan to implement wall breaks flowing towards voids instead of simply straight. What you are asking though includes those, but adds the void search to all water blocks. I'll create a todo issue describing this.
In reply to 13rac1:
In my second point I'm not asking for block breaking/removal but rather block collapsing/moving into a lower empty space either below or one block diagonally below randomly once it becomes waterlogged. This could occur several blocks away from liquid water due to water soaking through the soil similar to how farmland is irrigated.
I envision saturated earthen walls collapsing near the water flow rather than within the flow, much like a sand hole collapsing at the beach as the sand becomes damp. This would also cause earthen overhangs to fall if they become damp.
Vanilla rain triggers a splash effect on blocks exposed to the sky. A check could conceiveably be inserted to the call for rain splash to determine if the exposed block is suspended and trigger a collapse instead.
In reply to DrFraudAu:
Oh I see. Making all erodable blocks act more like sand and gravel when saturated, which would include clay, farmland, dirt, grass, and cobblestone. Makes me think: Perhaps the source wall breaks could push blocks like a piston does, except moving them to the sides to create stream banks.
In reply to 13rac1:
There have been several mods that implemented collapse physics but few have done it as a reaction to water.
Examples include; Enviromine and Fragile Blocks.
To my knowledge none of these have been updated past 1.12 and many, like Enviromine, have been abandoned. There may be an oportunity to look over their code form ideas.
Without more information, this mod just seems like a map griefer to me, even if it can look cool sometimes. So I'll ask, when does it stop? What exactly are the conditions for water to erode? Does flowing water have to hit a dead end for it to work? How far does it go? As someone who likes to make towns, villages, and other immersive builds in both survival and creative, this seems interesting, but there needs to be a limit. If it just keeps eroding non-stop, then it's really just destroying your map, realistic or not.
Also, is this only changing water behavior? I tried a mod a while ago that adds a similar result to your erosion called Streams. This mod added rivers and streams that actually flow at different elevations. However, they accomplished this by adding "new water blocks". This is an issue for people who use shaders like myself, because then you have a beautiful looking world rendered with shaders, but the water "blocks" added by the streams mod would not have shaders applied to them, and the result is really ugly...
I am interested in using your mod, but I just need some of these questions cleared up before I try it out.
In reply to JENOVA_Absolute:
The specific rules for erosion are in the description. I haven't explained the rules for V1.1.0+ block decay yet. I will update the description when I finalize them.
Erosion occurs at edges, dead ends, and hilltop lakes when downward flow is possible.
Seven blocks at the same height, just like normal water. I have not changed any stock water flow functionality.
Yes. Water blocks now can remove blocks under, to the side, or in front in the case of level 7 flows.
This is a mixin "coremod" adding to stock water. I don't want to create new water blocks and update world gen to create them. The goal is to create something which could be in the stock game as a default mechanic. The worlds of Minecraft are too static.
That is not the goal, but griefers will grief. Do not install where there are griefers or just accept the world is temporary. ;) Please try it out in a new separate world and let me know what you think.
In reply to 13rac1:
I know that "griefing" isn't the goal of the mod. It was just someone like myself who is obsessed with perfection as I build could only see it as such. Thank you for answering the questions I asked. I will try this out, since I know it should be compatible with shaders now, and see how I can work with it. The idea is unique. Whether I end up liking it or not, I won't deny it's a good mod.
I found this mod while searching Latest Updated mods for 1.12, but I can't see a 1.12 file under Files? (the tab itself)
In reply to inkdear:
Just an alpha so far, so it's not shown at first on the main Files tab. You have to view all https://www.curseforge.com/minecraft/mc-mods/water-erosion/files/2887102
really really cool, but i'd argue against making still water erode things
not only it doesnt make much sense, but an ocean would be the "laggiest" thing ever
In reply to GeekJokes_GJ:
Thanks! Still water must erode to make more streams and waterfalls than exist in the generated landscapes by default. The theory I'm going with is: Water on a hill will leak through the side and end up draining, after significant time this leak will create a stream. Minecraft is a low resolution version of reality. I'm just continuing the theme. FWIW I'm already skipping oceans with an early return:
if (pos.getY() <= world.getSeaLevel()) {
return;
}
Rad as hell. Since you've released a 1.12 port, would it be possible for you to look at compatibility with water from the Streams mod? Or maybe to make that a more flexible/universal request, a configuration option to add the functionality to user specified fluids?
In reply to Shampoohyay:
Thanks! Interesting! I'll have to check it out further. I'm supporting 1.12.2 now, but I hope keep major work to new versions. Blocktags are evaluated and used in 1.14+, anything tagged as leaves or sand will erode. A similar interface could be implemented for water.
there should be a config file so we can set which blocks are able to get eroded and which ones aren't
In reply to dietfreedom:
Yes, it was the first issue the todo list: https://github.com/13rac1/Minecraft-Water-Erosion/issues/1 Though, not by priority.
In reply to 13rac1:
also maybe adding a way to adjust how far water flows outward? that would help more with the man-made gorge i'm making
In reply to dietfreedom:
Do you mean more than seven blocks? I haven't changed the water flow mechanics at all. Probably would want to do that in a separate mod though.
