The drainage patterns of a stream system (a network of streams and tributaries) depend largely on the topography on the land as well as the structure of the underlying bedrock. Areas subject to faulting often produce rectangular drainage patterns, while areas with folded topography (mountains) often have trellis drainage patterns. Volcanoes typically form radial drainage patterns. Dendritic drainage patterns are common in areas with non-porous, impermeable bedrock.
