+# Amplified world generation without excessive flooded caves
+
+This datapack changes the noise parameters to remove flooded caves in amplified world generation.
+It achieves this by increasing the terrain density (= more stone/dirt) around y=46,
+which cuts off most surface water from the cave systems.
+It shouldn't make it harder to find caves since some seemingly ignore the inital density generation.

+## Removing all flooded caves
+
+It is also possible to remove normal flooded caves by decreasing the `fluid_level_floodedness` noise.
