Study Notes
Dendritic Drainage
- Resembles a "tree" structure; branches spread out efficiently.
- Minimizes the total length of drainage paths, conserving energy.
Trellis Drainage
- Common in regions with dipping or folded topography.
- Characteristic of the nearly parallel mountain folds found in the eastern United States.
Radial Drainage
- Occurs when streams radiate from a central peak or dome, such as a volcano.
- Stream flow patterns are directed outward from a high point.
Parallel Drainage
- Associated with steep slopes, resulting in straight stream courses.
- Formed where geological conditions allow for uniform drainage patterns along the slope.
Rectangular Drainage
- Develops in faulted and jointed landscapes, creating right-angle turns in stream paths.
- The network of streams exhibits a rectangular arrangement due to geological features.
Annular Drainage
- Characterized by streams that follow a circular path around hills.
- Often occurs when a layer of less resistant rock is present, causing streams to erode in a circular fashion.
Deranged Drainage
- Found in glaciated regions, particularly in the Canadian Shield.
- Lacks a clear geometric pattern and features a chaotic arrangement of streams with no defined valleys.
