The drainage pattern of the area shown can be identified as dendritic. In a dendritic pattern, the river and its tributaries resemble the branching of a tree, with each small tributary feeding into larger ones as they flow towards the main river. The pattern typically forms on relatively flat-lying sedimentary rock or uniform material, where the rivers and streams erode through the terrain in a uniform fashion. This is the most common type of drainage pattern and can be found in many regions around the world.
