Which type of river is characterized by a single channel?

A straight river is characterized by a single, continuous channel that flows in a relatively straight path. This type of river typically has a well-defined bank and minimal deviation from its course, resulting in a streamlined shape. The flow is often faster due to reduced turbulence and is less influenced by the surrounding landscape compared to other river types.

Meandering rivers, on the other hand, consist of a single channel that curves and bends, forming loops and bends as it flows across the landscape. They do not exhibit the linear characteristics of straight rivers. Braided rivers consist of multiple interwoven channels that separate and rejoin, creating a complex pattern of flow. Delta rivers form at the mouth of a river where it meets a body of water and sediment deposition creates a fan-shaped area, which can have multiple channels.

The distinguishing feature of straight rivers is their straightforward, single-channel flow, setting them apart from the other types mentioned.
