Question

Difference between dendritic and trellis drainage pattern

Answer 1

Trellis drainage patterns look similar to their namesake, the common gardentrellis. Trellis drainage develops in folded topography. Down-turned folds called synclines form valleys in which resides the main channel of the stream. The rectangular drainage pattern is found in regions that have undergone faulting.
