ACCORDANT AND DISCORDANT DRAINAGE PATTERN
Accordant drainage patterns. This is where the river and its tributaries flow according to the slope of the land the dendritic drainage pattern, annular, radial etc. on the other hand , discordant drainage pattern refers to a situation where there is no systematic relationship between the river and the underlying rock type and structure. Accordant drainage pattern Dendritic drainage pattern; dendritic comes from a Greek word Dendron which means tree like. This is a tree-like pattern of drainage in which tributaries’ coverage on the main stream from many direction and usually join the main river at acute angles i.e. less than 90 degrees. It develops in gently dipping areas which influence the speed of river flow. Conditions under which it develops It usually develops in areas of homogenous rocks with the same resistance to erosion e.g. granite It also develops in areas of gently sloping land It develops in areas of heavy precipitation or rainfall. All rivers and tributaries flow...
