Distributaries form when a river splits into multiple smaller channels as it approaches a delta or an area with low gradient. This splitting occurs due to sediment buildup, which reduces the river's capacity to carry its flow, causing it to branch out. Distributaries typically develop in regions where sediment deposition is significant, allowing the river to distribute its water across a wider area. Over time, these channels can evolve and change course due to ongoing sedimentation and shifting water flow patterns.
