define water divided what are the different patterns formed by the river with different river pattern
Answers
Water divide : An elevated area such as a mountain or an upland that separates two drainage basins is known as water divide. The four drainage patterns are as follows : (i) Dendritic-The dendritic patterns develop where the river channels follows the slope terrain. The stream with its tributaries resembles the branches of a tree, thus the name dendritic. (ii) Trellis-A river joined by its tributaries, at approximately right angles, develops a Trellis pattern. A Trellis drainage pattern develops where hard and soft rocks exist parallel to each other. (iii) Rectangular-A rectangular drainage pattern develops on a strongly-jointed rocky terrain. (iv) Radial-The radial pattern develops when streams flows in different directions from a central peak or dome-like structure.
