Study Notes
Stream Order Classification
- A classification system identifies characteristics of creeks, streams, and rivers based on their size and location within a watershed.
- The system assigns numerical designations to streams, helping categorize their order.
Stream Order Definitions
- First Order: Represents the smallest, permanently flowing streams; they originate in headwaters.
- Second Order: Formed by the confluence of two first order streams; typically consist of small streams.
- Third Order: Created by the confluence of two second order streams; represents a larger stream entity.
- Fourth Order: Formed when two third order streams join together, indicating an increased flow and size.
- Fifth Order: Arises from the confluence of two fourth order streams; showcases further increase in stream complexity.
- Sixth Order: Emerges from the joining of two fifth order streams, representing even larger and more significant water bodies.
Stream Order Hierarchy
- When two streams of differing order join, the resulting stream adopts the higher order designation, reflecting the larger stream's characteristics.
