Minecraft:River

Template:Infobox biome A river is a common aquatic Minecraft:biome that cuts through most land biomes. Rivers can serve as borders between various other biomes, and usually lead to Minecraft:oceans, although they are also able to form loops.

Generation

Rivers generate in land whenever the PV values are on their lowest; in the deepest part of valleys. River generation does not depend on temperature or humidity, meaning that they can cut through any type of land, but they are replaced by frozen rivers in the frozen temperature zones.

The shape of rivers is determined by the PV noise. They always twist around higher landmasses, sometimes they form loops that can be small enough to have no land inside.

Rivers do not generate in Minecraft:swamps or Minecraft:mangrove swamps, but their water bodies are often connected. The depth and width of a river strongly depends on the surrounding terrain; near Minecraft:oceans they are mostly wide, with some islands and flooded land biomes, further inland they often dry up with barely any water. Around Minecraft:mountains or elevated terrain, rivers form deep fjords with tall cliffs, and they abruptly end when the continentalness reaches the highest value. Here, no rivers generate and the valleys consist of elevated land biomes.

Rivers typically serve as a division between two different biomes, with one biome variant on one side, and a different variant on the other.

Description

A river biome on its own does not have many distinct features, most of its characteristics are created by the terrain generation or surrounding biomes. They are filled with still Minecraft:water up to the sea level, and the terrain below consists of default lakebed blocks, covered with Minecraft:seagrass. Specifically, it is separated into patches of Minecraft:dirt, Minecraft:clay, Minecraft:sand, and Minecraft:gravel.

When a river generates land, it is just covered by grass blocks with some patches of Minecraft:bushes. However, features from bordering biomes often leak into the river biome. This happens most notably with wooded badlands, where the grass allows many Minecraft:oak trees and leaf litter to generate. Due to the extended coastlines, Minecraft:firefly bushes and sugar cane are often found near rivers, although they are no more common than in other biomes.

No fully-passive Minecraft:mobs spawn within river biomes themselves, but they frequently wander into them from the surrounding biomes if they can spawn there. Minecraft:Drowned can spawn underwater, as can Minecraft:salmon and Minecraft:squid. Template:IN, no hostile mobs spawn above water.

Trivia

Rivers override Minecraft:canyons at or close to the surface level, causing the canyon to be abruptly cut off by a wall of stone. However, if the canyon is long enough, it may continue on the other side of the river.
- Canyons can generate underground in river biomes without being cut off.
