drainage pattern

drainage pattern
   The configuration or arrangement, in plan view, of stream courses in an area, including gullies or first-order channelized flow areas, higher order tributaries, and main streams. Drainage pattern is related to local geologic materials and structure, geomorphologic features, and geomorphic history of an area.
   Major drainage pattern types include dendritic, trellis, artificial, etc. Also called drainage network. SW, GG, &
