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.

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)

It's on my todo list, but working on other projects right now https://github.com/13rac1/Minecraft-Water-Erosion/issues/1
Fabric 1.16.1, Water Erosion 1.1.1 cobblestone stairs when converted to mossy stairs lose their orientation.
In reply to Deximus_Maximus:
Ah ha! That's a bug. https://github.com/13rac1/Minecraft-Water-Erosion/issues/24
So I just tried out this mod in Fabric, with Fluid Physics as well, and Oh Boy! do they work well together!
In reply to Lokuzt:
Good to hear, I'll have to try out Fluid Physics.
In reply to 13rac1:
Let me know what you think about the combination! I really think it's great, and would love even some kind of mutual support between these 2 great mods. UwU
i think water has three type of change. one is moisture, second is grind, and 3th. wave.
so" water streams form" is change erosion.
moisture is water surround block and nature growing(or rust)
most slow change. so it has enough time
it need slow or not move stream
waters every surround is source or block(so no stream) than it
kin of [cobble stone is mossy] is moisture work
grind is water's stream(and it has some dusting) heat and blocken
need powerful stream i thing "falling stream is hit ground" point is better.
it kind of [gravel to sand]
wave is water is move and take from surround.
its better of streams corner point kind of water split point.
and also this erosion is only decade block (so remove blocks). I thng add some kind of un-erosion mechanic (kind of stack dirt)
this my idea is i think we need more control-able mechanic to play game.
and also "just one small water make all over the world removing able" is not good sound for me
In reply to kjrsysy:
I understand what you mean about the different types of change: moisture aka soaking, grinding aka friction, wave aka pressure/movement. I don't understand the feature requests though. Maybe you mean that source blocks, since they don't flow, should cause a slower rate of change?
Un-erosion is basically "convert to block on despawn" in this issue https://github.com/13rac1/Minecraft-Water-Erosion/issues/3
Water is infinite in Minecraft, so one water block can cover a huge area if placed at 256. There's no good way around that without huge changes to the water mechanics like creating a complete water cycle and adjusting the world generation to make use of it.
In reply to 13rac1:
I see your first feature video and ['none stream' water pools wall is removed] is strange. and think about better and control_able thing idea.
with better thing.
i say wave need speed. so ["stream make river" than it surround grind and "more nature" form], and ["nature pool's wall" is "ugly grind and broken"] is not having.
also control able mean player control farm more Optionally.
if cobblestone is [grind to gravel] and [moisture to mossy]
than if player want gravel, player need to build higher structure for powerful stream to grind,
and want mossy cobblestone than build wide (and dark?) pool to moisture point.
and last "just br-br-br-" mean
"water hit every block erosion and just remove(yes that time i'm not yet see about that issue) however it hit.
so it can make one water make whole hole to hit bedrock(even spend so much time). that's feel disaster"
kind of like this think.
so sorry about yet deep knowing.
+ i'm not good english. sorry about you feel strange meaning about my text, too
In reply to kjrsysy:
My goal is to implement erosion near to real life, but to still make sense within the world of Minecraft. There is no such thing as a stream, river, or lake as far as the game is concerned. Everything is just blocks.
> than if player want gravel, player need to build higher structure for powerful stream to grind,
There's no quick way to measure how far a stream is falling. I'd have to count up the number of falling water blocks above the current one. It is an interesting idea though.
> so it can make one water make whole hole to hit bedrock(even spend so much time). that's feel disaster"
This mod avoids that problem by not eroding Stone. Only the blocks listed in the description are eroded. Stone erodes in real life, but it would make a large mess in Minecraft.
> + i'm not good english. sorry about you feel strange meaning about my text, too
It's okay. I understand most of what you mean. Keep working at it!
hope this doesnt apply to player placed blocks? would mess up any man made waterfall/lake/pond I create
In reply to sovlv:
There is no (good/efficient) way to determine what is or is not a player-placed block. Your custom waterfall/lake/pond will not be affected if it follows the new rules. This mod creates far more in-game water features, so there's a chance you'll be satisfied with them as-is now. Try it out on a new world using a high random tick rate. Fly around and explore what is created, before running the mod on your existing worlds.
1 - Would be nice to have rain and thunder speeding up the water erosion, like 1,5x and 2,0x respectively.
2 - Do you know the Forge mod Streams? Is a famous one that creates awesome realistic flows to rivers and make them much more dynamic, but it's outdated to 1.12 since January, so I don't think a port to Fabric could be possible at least not anytime soon. Do you think it's possible to add the features from the said mod or is it asking too much? XD
3 - In the sample video, I found it strange to see a forested area being eroded, and even more with the standalone tree in the middle. Since it's very uncommon to have landslide on vegetated slopes, in real life, it'd be great to have a erosion rule for this. If the area is deforested, then it becomes possible. Would it be too hard to define and configure it?
In reply to Zethos_VII:
1. Yes, I like it https://github.com/13rac1/Minecraft-Water-Erosion/issues/23
2. Yes, I know of Streams. And yes, it would be a significant amount of work to convert to 1.14+. Perhaps the project creator will upgrade it in the future?
3. Yes, landslides are uncommon, but erosion still occurs in a forest. The problem with changing this is: how to define a forest? You and I can see it is a forest, but teaching the game to recognize forested vs deforested is complicated. I have biome type and access to the blocks using (x,y,z) locations. There's no other metadata about the areas and I cannot "just" do a three dimensional search of an area, because it will use too much CPU-time. This is actually a similar issue to why I haven't implemented "place the dissolved materials downstream", because: how to define downstream? There's whole block group/area classification system (machine learning almost) needed for it to work well. Best idea I've got right now is I could reduce erosion odds in the direction of a stack of wood blocks (See how I have to define it? Trees don't exist according to the game either ;) ) This would cause flows to turn away from trees more often.
4.
Ha! I like this question. My reasoning is, because the dry grass gets watered. A flood of water would more easily wash away the grass path, but these flows aren't floods. So, I went with the grass growing before being stripped away. Either way works, I picked one.
Hmm. I wish there were a Cracked&Mossy type. I'll consider the ordering change. It doesn't break anything.
Why would water change this? I'm not seeing the connection.
In reply to 13rac1:
1 - Sorry, it should have been rain and storm instead, then the 1,5x and 2x speed up makes sense. I'm Brazilian, so I mistranslated 😅
2 - I read some of his progress in the Minecraft Forum, but it's been so long that I'm not giving much faith on it.
3 - Yeah, is very difficult like i thought. At least the last idea was good enough!
4 - Ho ho... I understand now. The erosion is slower than the grass growing, so it makes sense. Then Mycelium must not be eroded? I thought Podzol was the closest to be its block decay, since there can grow any sapling other than just mushrooms before. As if the water washed away the land's exclusive "funginess" 🧐
Might be out of the scope of the mod, but ever considered some kind of evaporation mod to effectively counteract/complement some of this mod's features? Would be cool especially if it had compatibility with Serene Seasons.
I just think it's weird to let water have such a huge potential to change the landscape when there's no system to balance when the water exists in the first place.
In reply to SandwichHorror:
I've thought quite a bit about implementing a complete water cycle including finite water. I don't see how it can be implemented without significant changes to the world generation. I like the idea!
The rules have been carefully balanced to make sense (at to me!) within the existing Minecraft world "physics," The current when balance is that there often isn't a massive amount of water stored underground in the default world gen. I've flown hundreds of blocks searching out interesting new water features in some worlds. It's dependent on world gen, not a predefined balance system. Try it out, set a high random tick and go flying in creative mode. Aquifers tend to group. You'll still find many dry areas depending seed.
can you config the amount of erosion for a certain time
In reply to james9236:
That feature is on my todo list. https://github.com/13rac1/Minecraft-Water-Erosion/issues/1 No ETA yet.
