Detailed explanation-1: -A pattern featuring a supporting structure of interwoven pieces of wood or metal (latticework) sometimes adorned with climbing vines or flowers.

Detailed explanation-2: -Trellis Drainage Pattern– In this type, the short subsequent streams meet the main stream at right angles. Through soft rocks differential erosion paves the way for tributaries. Examples include – old folded mountains of the Singhbhum (Chotanagpur Plateau).

Detailed explanation-3: -Trellis drainage patterns typically develop where sedimentary rocks have been folded or tilted, and then eroded to varying degrees depending on their resistance to erosion. The Rocky Mountains of BC and AB have some fine examples of trellis drainage.

Detailed explanation-4: -The Trellis drainage pattern develops in regions made up of alternate belts of hard and soft rocks. These rocks dip in the same directions and lie at right angles to the general slope, below which the main river flows.
