WaterPhysics
The WaterPhysics modification introduces realistic water physics into Minecraft with minimal impact on game performance.
Mod Features
Water in the game becomes a limited resource that follows the laws of gravity. Water sources can now move downward if there is free space beneath them. Water can also flow sideways when there is a water flow above the target area and diagonally under the same conditions.

Settings
For proper operation, it is recommended to set the game rule: /gamerule waterSourceConversion false
