Question

When does a Trellis pattern develop?
  1. When the river channel follows the slope of the terrain.
  2. When a river joined by its tributaries at approximately right angles.
  3. When a pattern develops on a strongly jointed rocky terrain.
  4. When streams flow in different directions from a central peak or dome like structure.

  • Trellis drainage pattern
  • The geometry of a trellis drainage system is similar to that of a common garden trelliesused to grow vines.
  • As the river flows along a strike valley, smaller tributaries feed into it from the steep slopes on the sides of mountains.
  • These tributaries enter the main river at approximately 90 degree angle, causing a trellis-like appearance of the drainage system.
  • Trellis drainage is characteristic of folded mountains, such as the Appalachian mountains in North America and in the north part of Trinidad.
