1. Dendritic Pattern:
This type of drainage pattern appears like a tree with many branches. It is formed when a consequent river receives a number of tributary streams, such that the streams join the main stream at a fairly acute angle of about 45°. This drainage pattern is produced in area that has homogenous rocks.
2. Trellis Pattern:
This drainage pattern is usually characterized by river capture. It occurs as a result of alternate layers of hard and soft rocks thus making the tributaries to flow parallel to the main river at almost right angle direction.
3. Radial Pattern:
This occurs where streams flows in different directions from the watershed like the spoke of a wheel. It is usually found on volcanic cone, which is only slightly denuded.
4. Centripetal Pattern:
This occurs when streams from surrounding highlands flow inwardly into a central depression of lake.
5. Annular Pattern:
This pattern of drainage can be found on naturally dissected dunes that have alternative beds of strong and weak rocks encircling them.
6. Rectangular Pattern:
This is where the main river is joined by all its tributaries at a right angle direction.
