Explanation:
Trellis drainage pattern:
- A trellis drainage pattern is characterized by a river being joined by its tributaries at right angles.
- The main river flows in a straight line while its tributaries join it at perpendicular angles, resembling a grid or lattice.
- This pattern is typically formed in regions with alternating layers of hard and soft rock, where the main river follows the softer rock and the tributaries flow along the harder rock layers.
Characteristics of trellis drainage pattern:
- Main river flows in a straight line.
- Tributaries join the main river at right angles.
- Forms in regions with alternating layers of hard and soft rock.
- Resembles a grid or lattice structure.
Comparison with other drainage patterns:
- Dendritic drainage pattern: characterized by a branching network of tributaries joining the main river at acute angles, resembling the branches of a tree.
- Rectangular drainage pattern: characterized by tributaries joining the main river at right angles but without the straight main river channel.
- Radial drainage pattern: characterized by tributaries flowing outward from a central high point, like spokes on a wheel.
In conclusion, the trellis drainage pattern is distinct in its right-angled junction of tributaries with the main river, creating a grid-like network. This pattern is influenced by the geological structure of the region and is one of several drainage patterns found in nature.

Trellis Drainage Pattern: When a river is joined by its tributaries at almost right angles, it develops a trellis pattern. Trellis pattern develops where hard and soft rocks exist parallel to each other.
