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.
Have an idea about how it could be even better? Let me know in the comments or issues!
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 this mod work serverside only or does it have to be installed by clients too?
In reply to chrys_alus:
Works fine server-side only my tests. Please let me know if you have any issues.
Hello, 13!
Hope you are doing well, during these times due to the pandemic.
I have a question. Well, a long time ago you said that you would evaluate the possibility of making a last update for 1.12.2 (regarding the speed of the erosion - basically, making it to slow down). Thus, is this update still possible? :s
Thanks in advanced for the response!
In reply to pseudohuman93:
Hi! Thanks! I've been working on a different huge non-Minecraft project. Just now able to get back to existing projects. Yes, I still plan to make that update for 1.12.2. ETA unknown right now though.
If you remove this mod Inna world that is already generated what effect will that have? I like the idea of the mod but it is really messing up the terrain on my current terraforged world. Anywhere there is water it just eats away and is completely wrecking the river banks making huge holes into chasms. I like the water fall effect coming down the mountains but it seems like it erodes river banks too much and too fast.
In reply to redleg101:
I designed the effect configuration around the default world gen where this never happens. How can I reproduce this issue? Just use Terraforged? There are no permanent effects if you remove it. Water's ability to erode anything will stop. It will not undo any changes of course.
In reply to 13rac1:
Thanks. I'm not complaining about your work on this mod, its pretty awesome and I think it's a great addition to the game. I'm think that for terraforged I just need to change the settings to work better with the mod.
In reply to redleg101:
Oh! I didn't interpret that you were complaining. I want to fix this issue, if it is possible. Can you tell me the steps to reproduce the problem? Is it fresh Minecraft work with Terraforged and Water Erosion? Are there any other settings to adjust or change in Terraforged?
Maybe this has been asked before (and I guess I should just try it and see), but does this mod create current in existing rivers and streams that would allow a boat for example to float downstream on its own?
In reply to redleg101:
No, just erosion. It makes new streams/creeks and waterfalls by adding functionality to how water works. It will not add current to motionless rivers.
That would be difficult, because the game itself has no concept of what a "river" or "downstream" is internally. Everything is just blocks. You and I see the river in the blocks, but the game doesn't. Could be an interesting exercise to implement it, but I'd make it a separate mod.
could you please add deposition it would simulate real life it could destroy farmland but deposit gravel and sand
In reply to tytolll:
I'd like to, but how is still a big question. You and I can see where the gravel and sand should be deposited, but I'm not sure how to implement it correctly. See https://github.com/13rac1/Minecraft-Water-Erosion/issues/3

i understand if you can take your time we love your mod me and my friends
forge 1.16.2 version?
In reply to MrAws0m3:
Yes, it is planned. Edit: Released.
My 1.12.2 game and server is crashing. This is really frustrating as i have wanted to use this for a long time only for it to crash.
Yes i have checked the issues and seen the 1.12 crash thing and did the stuff on the thread and it is still crashing. Please help me fix this.
In reply to g1ngerrobot:
Does this mod alone cause the crash? You must test with only this mod. If the game crashes without any other mods, then please post your crash log as a new issue on Github. If the game works with this mod alone, then the problem is elsewhere. I recommend testing half, then testing half of the result, a binary search, to determine the problem mod.
it's a really nice mod, but I really wish there was a configuration or via datapack the possibility to change, remove or add the various transformations of block and change time of tranforming block (very similar to recipe of datapack)
In reply to AlleCraft:
It's on my todo list, but working on other projects right now https://github.com/13rac1/Minecraft-Water-Erosion/issues/1
